产品概述

 Non-fixed water-proof thermocouple and resistor adopts φ3～φ8 armored thermocouple and resistor. Armored components are directly connected to measured  medium, with quick heat response. It adopts smaller water-proof box, compact and easy to install and adjust, used to measure the temperature of various substances


 Graduations:  K、E、J、T、Pt100、Cu50。
