Best Moisture Meter Buying Guide
Moisture meter has many features, specifications types, and characteristics. So if you get confused about making the decision to buy the right moisture meter for your work it is normal.
But if you do not get confused I think you are a moisture meter expert and you have clear knowledge about the characteristics of different types of a moisture meter and you know what you need. In that case, you do not have to read this section. You can jump to the next section to see the best moisture meters available in the market.
You should gain a clear idea about the following parameters before buying moisture meter:
10 Things You Need to Remember While Buying a Moisture Meter
There are mainly two types of moisture meter – one is pin type moisture meter and the other is pinless moisture meter.
The pin type moisture meter has a pair of probes that plunge into the test object and calculates the moisture level of that place. They give more accurate result but their downside is that you have to plunge pins into the materials to get the reading.
The pinless moisture meter uses a high-frequency electromagnetic wave to detect the moisture level in the test object. You do not have to make any tiny hole in the test material if you use a pinless moisture meter. They are more expensive than the pinless moisture meter.
For some test objects making tiny holes is not a big deal but for some object, you may not want to make any hole on its surface. In that case, what will you do? Will you buy two types of moisture meter?
Well, some moisture meters come with both features of pinless and pin type moisture meter. You can buy this type of moisture meter if you need both types.
You will not get a 100% accurate result from any kind of moisture meter – no matter how expensive it is or if it is made by the world-famous moisture meter manufacturer. It is impossible to manufacture a moisture meter that will give a 100% accurate result.
The lower the error rate the better the quality of a moisture meter. It is wise to choose a moisture meter that is accurate to within 0.1% to 1%.
3. Test Material
Most moisture meters work best for wood, concrete, and other building material.
4. Warranty and Guarantee Period
It is wise to check the warranty and guarantee period before buying a moisture meter from a particular seller. Also, do not forget to check the quality of their customer service.
Some moisture meter comes with an LED display and some LCD display. Though analog and digital LED is also available, LED and LCD are more common than these two. It is totally up to you which one you will like to choose.
You also should pay attention to the size of the screen and the resolution because the clarity and accuracy of the overall readings highly depend on these two parameters.
6. Audible Feature
Some moisture meters have audible features. If you have to use your moisture meter in darkness or awkward situation where it is difficult to see the screen this feature will come to your help.
Some moisture meters can save the readings for using later as references. It may not possible to carry a pen and writing pad everywhere.
8. Ergonomic Shape
If the moisture meter does not have an ergonomic shape you may feel it difficult to use it. So check whether it has a convenient grip to hold it comfortably or not.
9. Weight and size
A lightweight and small or medium size moisture meter is convenient to carry anywhere you want.
10. Battery Life
Moisture meters run over the power of the battery. If your moisture meter has a long battery life and good power-saving feature it will serve you for a long time.
The service you get from a moisture meter does not always depend on the quality of the moisture meter. It also depends on the way you are using it.
Calibration is the most important work to be done to get an accurate result from a moisture meter that we often ignore and get a result with a high percentage of error. If your moisture meter needs calibration and you have started to work without calibrating, then do not blame the moisture meter after getting an erotic result.
A moisture meter is a sensitive device. So it is needed to use with great care. Every time you use your pin type moisture meter do not forget to wipe the pins after using with a dry and soft rag and always cover the pins with a cap to protect these from dust and dirt. Pinless moisture meters also need to protect from dust and dirt.
Frequently Asked Questions
Q: How does moisture meter work?
Ans: The pin type moisture meters use resistance technology to measure the moisture level in a material.
On the other hand, pin fewer moisture meters use electromagnetic wave technology to measure the moisture level in a material.
Q: Can I detect mold with a moisture meter?
Ans: Technically speaking, yes, you can detect mold with a moisture meter.
Q: Which one is better – moisture meter or the manual moisture content calculation?
Ans: Well, both have certain advantages and disadvantages. It depends on the situation and your priority. Calculating moisture content manually takes more time and work but using a moisture meter you can do the task within less than a minute.
Q: Which one gives a more accurate result – a pinless moisture meter or a pin type moisture meter?
Ans: Generally, a pin type moisture meter gives more accurate result than a pinless moisture meter.
Q: How to calibrate a moisture meter?
Ans: You can calibrate a moisture meter by following 3 simple instructions step by step. Firstly, you have to place the probes of the moisture meter on the moisture content standard’s metal contacts. Secondly, you have turned the power on and thirdly, you have to check the reading & compare to value given in instructions.
Now check whether the reading matches with moisture content standard (MCS) set for. If it matches then the calibration is complete but if it does not match then the calibration is not done.
