Review on Supco TA22 Temperature Digital Display by Jesse Azuse

Works great! I use it to monitor the temperature in a small server closet to make sure the temperature doesn't skyrocket and damage the servers. I love the fact that it runs on AC as I didn't want to be constantly looking for a device that had to change batteries. The volume of the alarm clock is appropriate for my room (corridor on the nurses' floor in the hospital), when it rings, everyone in the corridor can hear it. The only thing not listed in the description is the ability to set an alarm to go off immediately when the temperature limit is reached, or you can have an hour delay to reset the time when the temperature falls below the set limit falls. This helps with small temperature fluctuations that can reach the trip point but are not a real problem.
