Outside Air Humidity Sensors with Temperature Transmitters feature closed cell foam to seal the probe insertion hole, mounting tabs for easy installation and etched Teflon leadwires to withstand high humidity and condensation. They comes with ±2%RH accuracy and an interchangeable 4 to 20mA or 0 to 5V humidity output or a 0 to 10V humidity output. The Temperature Transmitter has a 4 to 20mA output.  The units come with a watertight polycarbonate BAPI-Box IP66/NEMA 4 rated enclosure.

Humidity control is an important aspect of any climate control system. Therefore, humidity sensors must be both accurate and dependable. BAPI’s humidity transmitters are calibrated at 10 points from 10 to 90% RH for accuracy, eliminating field calibration. The Outside Air Units are also extremely dependable, featuring two of the most watertight enclosures available today. The BAPI-Box and BAPI-Box 2 are made of UV-resistant polycarbonate and carry an IP66 rating. The BAPI-Box is only available for units with a temperature transmitter and a humidity transmitter.
