Description :

The instrument is designed and made for Detection of Copper Corrosion from Petroleum Products by the Copper Strip Tarnish Test and ASTM D130 Standard Test Method for Detection of Copper Corrosion from Petroleum Products by Copper Strip Tarnish Test. It is suitable to determine the corrosiveness to copper of aviation gasoline, aviation turbine fuels, automotive gasoline, tractor fuels, washing solvent, kerosene distillate, lubricating oil, and other petroleum products. The instrument has functions of temperature controlling, automatic timing and alarming.
　　
Main technical features:

1. It adopts LCD temperature controller, heater and electric stirrer to form the constant bath. The temperature in bath     is uniform. The temperature controller has timing function. It can control the test time and automatically timing.         There will be alarm when finished.
2. The instrument has four sample holes. One bomb or three tubes can be put in each hole to be determined. The test     efficiency is high.
3. Standard color board can meet requirements of test method.
