Product Code: DH-1/50
The DH-1 duct humidistat delivers accurate electronic control of humidity levels in HVAC ventilation ducts. Capable of switching loads of up to 10A at 250V AC, it is ideally suited to the control of ventilation, humidification and dehumidification equipment; such as extract fans, boost controls, override controls, alarms, etc.
The DH-1 is calibration-free and accurate to within 3% RH. The high-accuracy humidity sensor is housed in a robust, corrosion-proof 50mm* probe, delivering consistent accuracy and maintenance free** operation.
The DH-1 regulates to a fully adjustable relative humidity set-point between 5% and 95% and a relative humidity hysteresis (differential) which is fully adjustable between 1% and 10%.
* Maintenance free in clean airflow. Any accumulation of dust or debris on the protective mesh filter may be removed by vacuuming.
**Please note this product is now supplied with a black probe.
Variants:
24 Volt (/24V)
Powered by 24 volt (AC or DC) supply.
