Elitech GSP-6 Temperature and Humidity Data Logger Recorder 16000 Points Refrigeration Cold Chain

Measures temperature and humidity accurately. Supplied cords are about 1.5 m long which were sufficient for me. Device has a magnetic back which can stick to any metallic surface. It can store many readings and present it in graphical format. I purchased it to measure the temperature in my refrigerator. However then I bought cordless device instead of this depending on my specific need.

Design is good, I have kept it outside our fridge and put the temperature probe inside the main compartment. It does record the temperature accurately. I have kept the humidity sensor outside to measure room humidity. There is another wire with a sensor, I am not sure why it is provided. The data logger connects to the desktop and you can configure it for the frequency of data logging etc. It is quite difficult to get it to restart recording since the user interface is not very descriptive. Reporting is okay.
