The values I can definitely on boiling water confirmed to be very good, because I possess not a calibrated measuring device is anything other than these water measurement speculation, my room temperature thermometer shows only minimal deviations from about 0.3 ° to this China meter, the question remains which discrepancies, has targeted objects could the data agree felt but that's of course no expert testimony, the fact is that the values at the same location are the same even with repeated measures.
Poor the China Thermometer is if I measure outside in the garden, the air temperature, there are to my mercury thermostat 4-6 degrees difference and that's pretty accurate.
If objects are measured in small distances seems this part to be really good.
The meter is practical and simple, the measurement width of minus 50 - plus 380 ° is of course far too high, with professional equipment, these can be adjusted or closer together, which is quite striking in any area I think.
Overall, I am nevertheless surprised, but when I hear that are heating so hydraulically balanced for the money really ok - or a heat efficiency of a house is to be measured then I can only smile and references rather be here by fluke, Flir or testo that Equipment cost is not for nothing that quickly 50-100fache
