high quality Molten Steel Thermodetector(WK-200A) made in China

ⅠMain Features & Applicable Ranges There are four graduations for user selection. This instrument can be matched with not only fast thermocouple for quick and accurate temperature measurement, but also industrial thermocouple to for continuous temperature measurement. With microprocessor as its core, this instrument conducts automatic calibration of null point, scale span and cold junction temperature for artificial circuit; Accurate reference source and software processing technology are applied to ensure the accuracy and reliability of the instrument; Double integral A / D converter is applied to enhance anti-interference. The casting thermometer is the optimal instrument for metallurgy, nonferrous metals, machinery and other industries, for it can operate automatically and reliably for a long term in severe environment and high temperature.
