产品概述

  Water proof(Aluminum alloy box) thermocouple adopts φ2～φ8 armored thermocouple. Armored components are directly connected to the agent to the measured medium, with quick heat response.


  The fixing device is a fixed thread, used to measure the temperature of various substances

Graduations: K, E, J, T, Pt100, Pt500, Pt1000, Cu50, Cu100.
