Thermometers
Multi-point thermometer

1.Application
(多点热电阻、多点热电偶)适用于生产现场存在温度梯度不显著,须同时测量多个位置或位置的多处测量。 The WRN-230D and WRN-430D multi-point thermometers (multi-point thermal resistance, multi-point thermocouple) are suitable for production sites where the temperature gradient is not significant, and multiple locations or multiple locations must be measured simultaneously. As a sensor for measuring temperature, multi-point thermometers are usually used in conjunction with display regulators, recorders, and electronic regulators to directly measure liquid, steam, gaseous media and solids in the range of 0 ° C to 1300 ° C in various production processes. Surface temperature. Multi-point thermometers are widely used in chemical fertilizer synthesis towers, storage tanks and other devices. zzyfwh.com
