Surface Duct Mount Humidity Transmitter

The HE-6700 sensors provide humidity and temperature sensing inside ducts and rooftop economizers. They are suitable for use with Johnson Controls direct mount Economizer controllers. The All-Polymer humidity element senses over the entire range of 0 to 100% RH, resisting corrosion and is housed in a plastic enclosure that is easy to install. These sensors are factory calibrated to NIST standards.
The ±2% models ship with NIST certificates of conformance to validate use in demanding HVAC applications.
Temperature and humidity information from the HE-67xx can be used to precisely calculate enthalpy, playing an important part in determining an energy-efficient and cost-effective economization strategy. Duct humidity is an important factor in the overall quality of indoor air. The HE-67xx allows you to monitor and compare duct humidity with levels recommended inASHRAE ventilation standards.
