Remote Alarm RH / Temperature Monitor by Sper Scientific Review

Average Reviews:

(More customer reviews)Not a bad product. The upper temp range is limited to 158F which was lower than I really wanted, so I had to position the sensor so the temperature was within range. These specifications were not documented here. The documentation shipped with the product is in broken english, but workable. The manual as well as user interface implies you can set either a low or high alarm, but it appears you must set both or the alarm sounds. Thus, after a bit of frustration, I was able to get this product doing what I needed. I am using it to warn me if my outdoor wood boiler runs out of wood or stops making heat for any other reason. I taped the sensor on the return pipe in the basement, and mounted the box above a light switch. I like that it has a replacable battery and that the cord is long enough - around 5ft.

Freezer Temperature Controller Review

Average Reviews:

(More customer reviews)Since my chest freezer dials only allowed for temperatures of freezing and below, or 50 and above, I had no way of keeping my kegs cold enough to where I like my beer (35-40 degrees).
But this device has been outstanding. To limit the frequency of which it turns on, I placed the thermometer in a glass/bottle of water. That way, when the liquid gets to cold, that's when the thermostat kicks in and turns the freezer back on until the liquid is at the desired temp. Also saves the compressor so it's not kicking on as much.
