Have one on both my Fridge and Freezer to monitor internal temperature. Alarm sounds if temp gets too high. Monitors both high and low temps. Great little monitor.
Great for an outside temperature for my truck
A150Q Min/Max Digital Thermometer with High/Low Alarm
The Tech Instrumentation A150Q min/max thermometer with alarm is a popular choice for monitoring refrigerators & freezers, terrariums, outdoor temperature in cars, computer equipment and many other applications. A high and low alarm can be set if desired. While in an alarm condition, the A150Q Min/Max Digital Thermometer beeps for 5 seconds out of every minute. If the unit returns to a non alarm condition, the unit stops beeping. The min/max memory can be used to see the highest and lowest recorded temperatures since the memory was last cleared.
Displays ambient & remote temperature (switch between one and the other)
Min/max temperature memory
High/low audible temperature alarm
Room & remote (outdoor) sensor temperature switch
