H7508A Humidity/Temperature Sensor

 

General

The H7508A Humidity/Temperature Sensor combines a capacitance-type relative humidity sensor and a Balco 500-ohm temperature sensor, mounted in one case.

The H7508A Sensor is used with the MicroniK 100, Excel DDC or DELTA 5600.

 

Features

• Extreme sensitivity
• High accuracy
• Wide range relative humidity sensing
• Stable characteristics
• Perforated cover for maximum air circulation and protection
