The Hygrothermo Pro from Garden HighPro is a professional digital thermometer and hygrometer designed for accurate monitoring of temperature and humidity in indoor cultivation environments, thanks to its reliable Japanese electronic components, which ensure precise measurements. Just like the brand’s Hygrothermo Premium and Hygrothermo Medium, the device features a large backlit display that clearly shows temperature and humidity readings, along with recorded daily minimum and maximum values. The green backlight activates only during readings, allowing growers to check environmental conditions without stressing plants with continuous light. A 1.5‑metre external temperature probe allows measurements at canopy level or inside specific areas of the grow space while monitoring ambient conditions simultaneously. With a temperature range of 0–50°C and a humidity range of 25–90% RH, the Hygrothermo Pro provides dependable climate control monitoring for indoor controlled environments.
