1. Application
WRN-230D, WRN-430D modelsMulti-point thermometer(Multi point thermistor, multi-point thermocouple) is suitable for production sites where temperature gradients are not significant and multiple positions or locations need to be measured simultaneously. As a temperature sensor, multi-point thermometers are usually used in conjunction with display regulators, recorders, and electronic regulators to directly measure the temperature of liquid, vapor, gas media, and solid surfaces in various production processes ranging from 0 ℃ to 1300 ℃. Widely used in large fertilizer synthesis towers, storage tanks, and other devices.
