What to consider when buying the Best hay moisture tester? 

There are so many factors you should take into consideration before making a hay moisture tester. It might be in what environment you are going to examine moisture, either in loose hay in the windrow, baled hay prepped storage, or one upon baling. It is recommended to find out your top requirements first before spending hours browsing the Internet in a sea of available products. We hope the guide below can be of some help.

1. Need a device for windrow or baled hay?

Determine whether you are in need of a device to test moisture in the windrow or of baled hay as there might be differences between them.

If there is loose hay in the windrow, it is best to buy a device that has a meter that employs an electrode with a disc-shaped prod. Why so? Because there are numerous open holes of air in the loose hay, and the multiple pin-points of a probe such as the Delmhorst F2000 can fix.

Whereas, hay bales are compatible with a long, reinforced prod as it can reach the interior of the bale to generate a result of moisture conditions deep inside of the bale. The length of the prod should be at least ½ to 2/3 the thickness of the hay bales.

2. Construction of the meter’s casing

Even the most rugged farming tools and equipment might not last long under the harsh conditions in the field. Hence, it is advised to be mindful of what equipment you plan to bring out there. When comparing hay meters, don’t forget to check the casing whether it is heavy and strong or light and poorly-made.

As the internal components of the moisture tester are quite sensitive, hence only secure meter cases can be a good shield for them in front of the rigors of farming work and avoid related damages.

3. The meter’s moisture range

A hay moisture tester should be able to measure moisture across the recommended range for your particular type of hay bale with 100% level of accuracy.

The optimum moisture content of a hay bale is affected by the type of forage and bale density, however, you might find the most common ranges as below:

  • Small square bales: 18-20% MC
  • Large square bales: 12-16%
  • Round bales: 15% MC

No matter what type of tester you would like to purchase, please make sure that its meter can detect moisture over a range of 8% to 30% MC exactly and get accurate readings of actual measurements rather than just a result showing that the hay is under or below the % MC range.

4. For baler-mounted testers, check the continuous mode

If you have to check the hay moisture while you are baling, without an appropriate meter, you might have to leave the cab of your tractor a lot. The meter you need to search for is one with a continuous mode to measure hay in a baler. Then you don’t have to go anywhere and just keep your eyes on the moisture conditions of your hay bales.

5. The meter’s calibration

Even the best moisture tester might not be able to work well after years. To make sure that the results you receive are correct, you should follow the simple and convenient below to check the meter’s calibration.

For a hay meter, you can use either a Moisture Content Standard (MSC) or a built-in calibration check. An MCS is a tool whose function is to provide a specific reading value when linked to a moisture sensor probe. If the reading result is not the same as the value, then it is possible the meter is off-calibration and needs a fix.

Built-in checks have the same functions as an MCS, but there is no need to have an external device which is a moisture sensor probe.

6. The warranty

You should find the warranty written in a way that is simple and understandable. They also state clearly what is and isn’t included, covered, and how repairs or replacements will be dealt with. That means the manufacturer understands its product and knows that their product is of high quality.

In contrast, if you find the warranties doublespeak with a lot of exemptions for daily use, there is a high chance you might not receive the expected service and support as promised.

Another way to help you find the best supplier is to look for other customers’ reviews, find out how the manufacturers have handled warranty service. By this, you can have a bigger picture of the company’s service and support and the quality of the product itself.

7. Description of usage or training course

It is not difficult to differentiate between a good manufacturer and an excellent manufacturer. That is how they provide customers with instructions. While a good toolmaker might write very detailed and comprehensive online product manuals, an excellent manufacturer might even produce a tutorial or even a training course on how to use the product to make sure you have no difficulties with it at the beginning.

You can go to their website to find out online manuals, brochures, videos, or training courses offered by moisture meter manufacturers. Knowing whether it is easy or difficult to use a piece of equipment can also affect your decision.

How to test moisture in hay bales? 

There are several ways to test a hay bale moisture before putting it into the silo. And each approach has its own advantages and disadvantages.

1. By hand

This is considered one of the oldest methods to assess the moisture content and quality of their produce. Its convenience is that you don’t have to use any tool but your own hands.

With this method, farmers take a handful of hay out of the bale, twist or rub them together in their hands. When they open their hands, they will see how dry or moisture the hay is and whether the hay can hold its shape or not. However, this is not a perfect option. Why?

  • You need to accumulate experience in order to be able to feel the hay by hand and give a correct reading of the bale’s moisture content.
  • And even if you are an experienced farmer, the random bundle cannot represent the whole bale. And most farmers often test the surface sample rather than the core hay in the bale and it is always affected by the weather.

However, if what you want is just a general assessment of the bale, it can give you a very quick guess.

2. By oven drying test

There are a number of different oven-dry tests using a different kind of oven/heating element, including convection ovens, microwave ovens, and even in-field testing apparatuses.

However, it doesn’t matter which kind of oven you are testing, the process to find out the moisture content is quite the same:

  1. Weighing the hay sample before drying.
  2. Drying the hay (this task can take 20-40 minutes, subject to the drying method and overall moisture of the hay). Sometimes you might need to keep drying the hay until the weight is fixed.
  3. Weigh the dry hay to have the “dry weight.”
  4. Divide the dry weight by the wet weight, and convert it to a percent number. Subtract this number from 100 to have the moisture percentage.

If you prioritize accuracy, this is what you are looking for. However, the inconvenience is that sometimes it can take you hours or even days to assess the moisture. For example, if you use the convection oven drying method, it might take you 24 hours to dry out the hale at 165°F. Yet with an already baked hale, you don’t have to worry about the time except when it is rainy. Then your previous assessment will be no use.

Plus, in case you want to have a reliable result for your hay bales, you might want to take a large enough sample size. It is recommended to take samples from different bales, which is not practical at all, especially when you have to make a lot of hay bales within a short time.

3. By moisture tester

test moisture in hay bales

If the two methods mentioned above do have disadvantages related to time and accuracy. I am confident to say there is another testing method that can solve such problems. It can produce the exact results quickly: hay moisture probes.

There are many options for you to choose and they can be all rugged and reliable devices, from baler-mounted units that can check moisture while the hay is being baled to portable units that farmers can bring them along and randomly check moisture content in hay bales before storage.

The process is simple. You put the probe in the hay bale, switch it on and the device will do the assessment for you. There are many moisture testers that can generate results within seconds.

In a nutshell,

What purpose and what type of hay you’re planning to test? The answer to this question affects you a lot on buying the best hay moisture tester for your farm.

If you’re finding a common tester for hay bale, our top choice for you will be the first pick – Agratronix HT-Pro. For a windrow hay moisture tester, don’t hesitate to buy the third one in our list from the best-rated Agratronix brand.

The best baler-mounted hay moisture tester will go to the Agratronix BHT-2 model. Though the price is sky-rocketed, its function will please you once used. Still want something for a low cost? TK100 tester is waiting for you on the market, dear.
