Long Probe Stem and Sheath
In order to get the most accurate measurement, remember that the heat of your compost will be much different in the middle than it is on top.

Most people have a particular measurement unit that they prefer. Whether you like reading temperatures in Celsius or Farenheight, you should have the ability to do both. A high-quality compost thermometer will come with dual-scale measurement so that everybody can read in the unit that they prefer the most.
Waterproof and Anti-Fog Lens

Some of the best compost thermometers come includes with specific instructions on both how to use the thermometer and how to properly compost. If you are new to composting or using a compost thermometer, this will come in handy.
Things to Consider Before Buying a Compost Thermometer
Compost thermometers can be the hardest gardening tools to search for. This is perhaps due to the limited knowledge on how to use them, and the features characterizing the best product.
That said, what should you really consider when searching for a compost thermometer? Here are the four main features to look for.
The standard temperature readings vary from different regions or continents. Whereas other counties use degrees Celsius as their standard, others prefer their readings in Fahrenheit.
A good example being that those living in America will like their readings in Fahrenheit while those in the UK will want a thermometer measuring in degrees Celsius. Different thermometers provide varying readings. However, it is prudent to consider a dual scale thermometer, offering readings in both measurements.
Compost temperatures are usually taken from the center of the compost heap/pile. Therefore, you would want a thermometer that reaches the center of the heap, without breakage or kinking.
Therefore, consider a thermometer with a long and thick probe. This will ascertain that you make accurate measurements, whilst ensuring that the stem doesn’t break easily when being used.
Compost piles never lack moisture. Besides, you could be leaving your thermometer in the compost pile for quite a long period. Therefore, it is of immense importance that you get a rust-resistant thermometer. It should also be sealed tightly to prevent water leaking to the dial.
Nearly all high-end compost thermometers come with three classifications of temperature range, i.e., the steady, active and hot zones. This makes it easier to monitor the temperature levels of your compost heap. Additionally, small temperature increments, of up to 2 degrees Celsius makes it easy to detect even the slightest changes in temperature.
When and How Often Should You Turn?
Many gardeners prefer turning the heap after each burst of heat. Others prefer turning based on the number of days. However, this isn’t a scientific approach to making a good quality compost heap.
So to say, compost should be turned when the temperatures reach between 140 degrees to 150 degrees. It should be left until it achieves this temperature again, probably after 5 to 7 days.
What Makes the Pile Heat Up?
Perhaps this is the most interesting question of the day. The contents of your compost heap heat up due to the actions of Microbes. The heat generated through the microbe’s metabolic activities such as eating, excreting and multiplying is responsible for such heat.
Bacteria is the common microbe responsible for this, but fungi and large soil organisms can also be found. The increasing intensity of microbe activity is the reason behind increasing temperature levels with different stages.
Ready To Buy The Best Compost Thermometer?
To ensure that your compost pile matures effectively, you must consider using a compost thermometer. However, not any thermometer can ascertain this, but the best can.
As mentioned, readings obtained from this instrument guides on the various changes and additions made to the heap.
Among the changes includes when to turn, when to open up, when to add water and when the heap is ready. Note that proper monitoring of this is a receipt for a high-quality compost heap result.
As mentioned the best thermometer ought to be made from the strongest material, have appropriate probe length and favorable measuring units. This will make it easy to read and monitor temperature changes in your heap.
