  • Introduction
  • Specifications
Our factory is a professional thermometer factory with 30 years history of production, strong design strength and exquisite manufacturing technology. In 1983, our factory has been designated by the former Ministry of Machinery Industry to provide completed thermometers for 300,000, 600,000 kilowatts generator sets and auxiliary equipment
With the continuous development of China's electric power industry, we urgent need a variety of thermal resistance and thermocouple which suitable for power plants to replace imported products.
In order to catch up with the international advanced level and save foreign exchange, our factory successively introduced professional manufacturing technology and equipment from abroad. On the basis of the original product, we accept design institutes and user’s advice and reference to the United States EBASCO to redesign products. We add new models and satisfy the requirement of domestic or imported 300,000, 60 kilowatt generator set, as well as other units. We provide excellent quality products to satisfy market.

Thermocouple Insulation resistance:
Testing voltage: DC500V。
Atmospheric condition:temperature 15~35℃,RH 45%,atmospheric pressure 86~106Kpa。
For longer than 1 meter thermocouple:Rr·L≥100MΩm  L>1m
Rr-insulated resistance under normal temperature( MΩ);
L- The length of the thermocouple (M)
For the length equal to or less than 1 meter thermocouple, its temperature insulation resistance value should be no less than 100 MΩ.
Thermal Resistance Insulation Resistance:
