S+S On-wall Hygrostats - AHT-30W-U LCD

Discover the cutting-edge S+S On-wall Hygrostats - AHT-30W-U LCD from a renowned manufacturer, S+S Regeltechnik GmbH. This electronic surface-mount hygrostat and/or thermostat, the HYGRASREG® AHT-30, features continuous and two switching outputs, adjustable switching thresholds, and a display for real-time humidity and/or temperature readings (accuracy class ±2.0% RH). It allows for setting target values corresponding to relative humidity and/or temperature.

Features and Benefits

Designed for precise control and monitoring of relative humidity (dehumidification/humidification) and/or temperature (heating and cooling), the AHT-30 is ideal for applications in laboratories, production areas, climate chambers, swimming pools, greenhouses, and more. It efficiently handles the regulation of dehumidification devices, heating systems, and cooling systems with a digital, long-term stable sensor ensuring accurate humidity/temperature measurement in clean, non-polluted air.
