Application scope of temperature measuring partner: industrial production temperature measurement, mold temperature measurement, steel chemical industry, glass, ceramic field, electricity, mechanical temperature measurement, heating, ventilation and air conditioning temperature measurement. When measuring boiling liquids, do not let smoke or boiling water vapor come into contact with the temperature sensing area, and keep the measurement angle at about 45-60. Insert the K-type thermocouple plug into the thermocouple socket of the instrument according to the positive and negative polarity marks. The thermocouple probe contacts the measured object. The screen displays the K-type thermocouple temperature. Using high-quality sensors, accurate measurement of sudden temperature differences makes the response more sensitive. Laser point and positioning quickly locks the measurement range and the measurement value is more accurate. The ratio of accurate positioning measurement, measurement distance and measurement target diameter is D:S=50:1. Determine the surface temperature of an object by measuring the energy reflected from the surface.
