Economy Wall Humidity Sensors
HEW

HEW Economy Series humidity transmitters offer an array of humidity control solutions at an affordable price. The thin-film capacitive sensor elements provide high accuracy and performance. The wall mounted HEW models feature an attractive, yet discreet housing, with simple installation. All Economy models come with a standard one-year warranty.

Reduce Installation Costs with Combination Sensors
• Monitor humidity and temperature with a single device
• Semiconductor, temperature transmitter, or popular thermistor/RTD sensors available
• Housing is low-profile...perfect for schools, museums, etc.
