Today we'll MMG - 3 the greenhouse thermometer, for example, talk about greenhouse thermometer in what position is more appropriate. Model: MMG - 3 types: maximum and minimum thermometer, greenhouse structure: the thermometer can flip eaves, elliptic button material: beige ABS shell temperature range: - 40 - 50 c, red and black single calibration accuracy: + / - 1 c such a greenhouse thermometer, if directly in the sun, to measure the surface temperature of the thermometer, because sunlight surface thermometer is heated, the temperature is generally higher than the surrounding temperature, the measurement of the thermometer features determines the measurement results of this case is a temperature rather than the surrounding air temperature on the surface of the thermometer. Poorly ventilated place because heat is inadequate, the air temperature can only reflect the status of local temperature, and temperature have the obvious difference. So greenhouse thermometer should be in a cool ventilated place, so as to ensure that the measured temperature of the surrounding.
