Extreme Accuracy Class: The "xw" designation signifies the highest tier of sensor performance. With temperature tolerances as tight as ±0.1°C and humidity accuracy of ±1.5%, the HTP.xw is the world's most accurate digital humidity/temperature sensor of its kind.
Barometric Pressure Monitoring: Beyond climate control, the HTP.xw tracks atmospheric pressure to typical ±0.5mb accuracy. This is useful for weather tracking, VPD calculations, and monitoring altitude-sensitive equipment.
Water-Resistant Durability: Like its sibling the HT.w, this unit features a sensor membrane and O-ring seals, built to withstand condensation, high humidity, and accidental splashes – safe for wine cellars, greenhouses, and humidors.
Data Redundancy: The device holds close to a month of history on-board. If you step away or your internet goes down, the HTP.xw keeps logging. The moment you reconnect, it seamlessly pushes the missing data to your app.
