Best Moisture Meter for Plants Buying Guide?

The first step in mold prevention. Yes, that's right, a moisture meter lets you check for suspicious water stains with ease. Consider these top factors when buying a moisture meter.

What is a Moisture Meter? 

Otherwise referred to as a moisture detector, this is a portable measuring device that you use to evaluate the content of a sample. Usually, these devices have large displays that indicate the moisture values as percentages, with some classifying whether a sample has high or levels of moisture.

What is Moisture Meter Used For?

These are highly dynamic tools that you can use to evaluate the water content of various samples by using electrical resistance. More so, these meters are often applicable for multiple applications and to ensure that organic items such as food, wood, oils, and even plants have adequate moisture.

How is Moisture Measured?

The moisture content in the percentage of the amount of moisture that comes from a sample after heating through a unique electrical current. Most digital moisture meters come with predefined settings, which makes it easy to get readings. 

Can a Moisture Meter Detect Mould?

Mould is a regular concern when working with wooden products. Thus, forested areas and places with lots of trees must be monitored daily to prevent the development of fungi. The moisture meters work well to prevent fungal growth and its spread on wooden surfaces. Any moisture content readings that move above 20% will cause mold spores to develop. 

Things to Consider

  • Ensure that the meter has adequate power before you perform readings

  • Ensure that you place the sample on a flat platform

  • Ensure that you remove all moisture and residue from the surface of the sample

  • When using the pins, ensure that they are all correctly installed to provide accurate readings

How to Calibrate a Moisture Meter

The calibration process for a moisture meter depends on the specific type of moisture meter you are using. That said, the pinless types are easy to calibrate, suing a unique calibration block kit that you can order from the brand company. For additional information on calibrating moisture meters, check the instructions guide on your meter guide.

Best Moisture Meter Features

These are gardening devices that have many different design features and functionalities. You have to consider all these factors when getting the best moisture meter for your needs:

Ease of Use Features

The best moisture meter should come with features that make it simple to use, regardless of the garden or farm setting you have available. It should be accurate and easy to read, especially when you have several houseplants. You should not have to remember the plants you watered, and you just check the moisture meter accordingly. 

There are various key features to consider when it comes to ease of use. They include:

  • Large dial – a large dial makes it easy to calibrate the device to suit your needs. The dial should also be ergonomic to make it easy to use 

  • LCD functionality – the device should have an LCD screen for easy viewing, and hold function which lets you freeze a reading

  • Auto shut down and low battery indicator – the auto shut down helps to conserve battery power. More so, the low battery indicator shows you when its time to recharge.


Aside from measuring the moisture levels of plants, the moisture meter should be dynamic enough to suit other applications. For instance, the meter should be suitable for use in the lawn, farm, yard, and even for potted plants. It is also essential to use for some delicate plants, which are sensitive to issues such as under-watering.

Probe Sensor Quality

The ideal probe sensor for a plant should be able to measure water at the root level. It is perhaps one of the most critical components of the moisture meter. Be careful when choosing a meter, because some brands are known for producing devices with frail probes. Furthermore, it should also be suitable for use with big potted plants. The probe should also penetrate most types of plants with ease. The last thing you want is a weak probe sensor that fails to cut through your tomato plants for moisture measurements. 

Heavy Duty and Waterproof Design

The moisture meter should also be durable enough to withstand anything that you throw at it. This is especially true because most gardening projects require durable tools for the purpose. Evaluate aspects of the meter, such as the design construction and the ability to withstand such problems as high impact falls. Even more, you want a waterproof moisture meter, mainly because you have to make moisture measurements in between plants.


Managing the overall health and development of your garden plants is crucial to the quality of yield you should expect. There are various minute details, that can easily take your yield quality to the next level. With resources such as the best moisture meter for plants, you can be sure of a convenient tool for making moisture measurements.
