Product Overview

The HW2 Series of humidity sensors for living space is a exible multisensor platform for use with BAS controllers

designed to accept 4 to 20mA, 0 to 5Vdc or 0 to 10Vdc outputs. HW2 Series sensors are available with three user

interface options: touchscreen, LCD with three buttons and blank. Humidity and temperature sensors are included

with all HW2 Series sensors.

* Replaceable 1% with NIST certicate, 2% with NIST certicate and 2% elements available.

** Available in HW2XA2G only.

*** Available in HW2XA2R only.
