Two measurement errors of outdoor metal thermometers

Have already visited: 12209/23/2020  

1. High temperature range

The temperature range of the outdoor metal thermometer is 200~650℃, and the allowable error is about 1% of the scale range. In fact, this is wrong, because this metal plate is made of a spiral thermal conductivity sensor, which is prone to fatigue at a high temperature of 650°C and has a large temperature difference. Therefore, when the temperature exceeds 550°C, a thermocouple should be considered to solve this problem. problem.

2. Low temperature range

It is clearly pointed out in the relevant information that the temperature range of the outdoor metal thermometer is 200~650℃ (this is incorrect), and the low temperature can be measured to -40℃. In fact, this is not much, because the temperature calibration of outdoor metal thermometers is usually -20°C.
