The HAHD Series has been discontinued and has been replaced by the HAHSDT Series.
The HAHD series uses a highly accurate and reliable thermoset polymer based capacitance humidity sensor and state-of-the-art digital linearization and temperature compensated circuitry to monitor humidity levels. The sensor is encapsulated in a 228.60 mm (9”) long by 12.7 mm (0.5”) diameter 304 S/S probe. An 60 micron HDPE filter protects the sensor for contaminants. A variety of enclosures are available. Various integrated high accuracy temperature sensors are also available.
