Digital Thermohygrometer with Probe

Digital max-min thermo-hygrometer with temperature probe. The thermo-hygrometer measures temperature and humidity at the device's location and has a 3-meter probe to measure temperature at a distant point. Measures from -30 to 70 °C, records maximum and minimum temperatures, 3-meter long probe to measure temperature in two areas far from the crop. Measures from 25% to 90% humidity, records the maximum and minimum humidity in the crop. Operates on 1.5-volt batteries. It is usually placed at the base of the pot, away from fans, humidifiers, and heaters, to provide the most homogeneous measurement possible, without being altered by air currents or the high temperature of the light source.
