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.

I'm a refrigeration tech that is just got into the field and this a great starter product it's cheap and works great
I'm buying a replacement because I use it in my truck and it works well. Because there's no metal to attach the magnet to, I lay it in the little coin compartment above my left knee. I pick it up to read it, so the wire gets flexed a lot where it enters the housing. The insulation wore off and the wire shorted out, so I get a reading of HH.H for the outside temps. I'll probably reinforce the wire on the new one with tape or silicone caulk.
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
