Good value and comparable with more expensive units,
Verified Purchase(What is this?)
This review is from: IVSOŽ Indoor Outdoor Digital Thermometer With 2 Sensors (Electronics)
Received this unit very promptly - no AAA battery included hence 4 stars. To test it I put it in an unheated bedroom and left for 2 hours with the door shut so air temperature would be stable and draft free. A Maplin unit costing twice as much showed a temperature of 15.1 C, a mercury filled Brannan Max / Min showed 15 C and this unit showed 14.9 C internal and 15.2 C external. Putting the probe into our freezer gave a minus 20.2 C whilst the Bosch readout for the freezer said 18 C. However the small circular freezer thermometer which I had always thought to be inaccurate was reading minus 20 C. As far as I am concerned this seems to be accurate enough and I will be ordering a second unit for the greenhouse propagator.
