Digital thermo-hygrometer with probe

Cornwall Electronics' Digital Thermo-Hygrometer with Probe brings together two essential measurement tools for grow room management.

this instrument, in fact, is very useful for simultaneously recording the minimum and maximum values of temperature and humidity, detected with the probe during a given period of time.

Humidity and temperature are two key parameters to check when starting a cannabis grow. The environment in which the plants grow, in fact, must not be too dry or too humid. The digital temperature and humidity meter with probe is excellent for monitoring any sudden changes that could compromise the correct development of plants in indoor cultivation .

This meter features a large LCD display that allows you to quickly read the time/date, temperature, and relative humidity. In addition, it is equipped with a very useful memory function that allows you to keep the last recorded values.

Operating mode of the digital thermo-hygrometer with probe

The thermohygrometer is a very simple tool to use, even for those who are not experts. This is thanks to an easy-to-read digital display and very intuitive operating keys:

• IN/OUT key to change display;
• C/F key to change from Celsius to Fahrenheit;
• CLEAR key to erase the memory;
• MAX/MIN key to view maximum and minimum levels of temperature and humidity;
• When the humidity level is lower than 40% it will read DRY;
• When the humidity exceeds 70% it will read WET;
• With humidity between 40% and 70% and the temperature between 20°C and 25°C it will read COMFORT.

Warnings and advice

This tool is indispensable for measuring the exact values of humidity and temperature of a crop, and it is even more useful if you are growing inside a heated mini greenhouse.

In this regard, it should be remembered that the maximum temperature must never exceed 27°C (with the lights on) and must never be lower than 16°C (with the lights off). While the ideal humidity should be between 60-70%, in the growth phase of the plants, and between 40-60% during the flowering phase.

For effective use of the digital thermo-hygrometer , it is advisable to position the probe directly in the middle of the crop: in this way there is no risk of altering the temperature measurement.
