Product Description
AVTECH Digital Temperature & Humidity Sensor – 50 ft RJ-11 Cable, Plug-and-Play for Room Alert Monitors
This used AVTECH Digital Temperature & Humidity Sensor is designed for monitoring ambient indoor temperature and humidity in server rooms, data centers, laboratories, and other critical facilities . When connected to a compatible Room Alert environmental monitor, this sensor provides real-time readings for temperature, humidity, heat index, and dew point .
The sensor features a small probe (approximately 2″ long) with a blue cap that contains 24 air holes for accurate airflow around the sensing components . The 50 ft RJ-11 cable allows flexible placement of the sensor away from the monitoring unit, making it ideal for remote monitoring applications .
Condition Note: This unit is untested and sold as-is. This listing is for the sensor only; no Room Alert monitor is included.
