Home / FH-Series Air Velocity, Temperature, & Humidity Sensor
Airflow sensor for measuring non-directional air velocity, temperature, and humidity.


Robust Air Velocity & Air Temperature Sensor

The FH-Series is a platform of non-directional air velocity, temperature, and humidity sensors optimized for demanding applications including laboratory, HVAC, high-performance electronics, and more. With both digital and analog outputs, which can be used simultaneously, the FH-Series sets a new standard in flexible design integration and airflow control.
Special airflow sensor coating for longevity in corrosive environments.

Conformal-Coated Electronics

Robust, UV-tolerant, splash-proof enclosure for use in corrosive or alkaline environments.
Choice of air velocity range, supply voltage,  mechanical length, and output communication style.
Analog & Digital Communication
Supports 0-5V, 0-10V, and digital UART or I²C communication outputs
Universal Supply Voltage
Suitable for applications where DC supply voltages are encountered.

Innovative "Outside the Duct" Installation

Single hole for mounting sensor assembly, without the need for screws or hands inside the duct
