 This self-powered, multi-channel data logger effortlessly and accurately logs and records temperature and relative humidity data and can be easily expanded to monitor additional parameters, such as indoor air quality, simply by connecting a wide range of off the shelf sensors.

 
A first in the industry, the ACR SRX2 introduces two-stage alarming (Warning and Critical) to alert users of situations that might be headed to critical status before actually reaching that critical point.
 
Two-stage alarming gives the user the ability to set both high and low alarm thresholds on two separate channels and send notifications of conditions as they change or progress towards a critical end point. For example, the SRX2 can notify the user that the temperature of a fridge is beginning to fail (Warning) before the temperature change can affect the stored product (Critical). The SRX2 is the perfect solution for critical process monitoring.
