Electronic Humidity Sensor
Description
AGM’s Electronic Humidity Sensor (EHS) delivers extended humidity monitoring and indication for sensitive equipment in the most extreme storage conditions. Developed in conjunction with the U.S. Army for long-term munitions storage, the EHS logs data hourly and will deliver over 20 years of memory and battery life.
The EHS displays its status via a single colored light when prompted either by directed infrared light or by touching the sensor. A green light indicates an acceptable humidity level, while a red light indicates a potential problem to be investigated further.
The EHS is programmable for user-specific thresholds for relative humidity or Parts Per Million (PPM) of moisture. For redundancy, the EHS incorporates a standard color changing humidity indication card.
Key Features Include:
- 20-year battery life
- Hourly data logging with memory for 20 years
- Data can be downloaded from the sensor to Excel via infrared without removal from the container
- Compact size – fits into a standard 1” hole
- Rugged design
- Backup passive color-change humidity indication card
