Product Description

High Sensitivity Bimetallic strip Truflex P675R

(Common Name: Truflex P675R, Chace 7500,Telcon200, Kanthal 1200)
Bimetallic 5J20110 holds very high thermal sensitivity and higher resistivity,but the modulus of elasticity and allowable stress is lower,it can improve the sensitivity of the instrument,decrease the size and increase the force.
