WZP assembly type thermalresistance

Brief Description

The WZP-431 assembly typeresistance thermometer is used with displayer, recorder and electrical adjustercompletely. It can measure the temperature of liquid, vapor, gas and thesurface of solid from -200℃ to 420℃directly. Per national regulation, we have manufactured PT100 platinumresistance thermometer in line of IEC international standard graduation andCU50 copper resistance in line of professional graduation since 1987.
