Standard Heating Pipe Constant Temperature Calibrator

Overview
PT-WT-3 standard heating pipe constant temperature calibrator adopts the JJG161 Verification Regulation of Standard Mercury-in-Glass Thermometers and JJG 130 Verification Regulation of Liquid-in-Glass Thermometers for working. Appropriate for calibrating and regulating various kinds of thermometers and sensors. Also it can replace oil groove and salt bath as constant temperature bath. The instrument’s measuring scope ranges from 200℃ to 400℃.
This instrument passed the technical verification of the People's Liberation Army General Logistics Department, and won the third prize of scientific and technological achievements, Liaoning province quality measurement test institute positioned the product as quality guarantee products, and obtained the national patent in 1997
