I.Purpose 

• GD-2430 Engine Coolant Freezing Point Testing Equipment  is designed and made as per the National Standard GB/T2430 "Test Methods for Freezing Point of Jet Fuels", and Industry Standard of Petrochemical SH/T0090 "Test Methods for Freezing Point of Engine Coolant".

•  If select different configurations, the Multipurpose Equipment Freezing Point Determination Apparatus can be used to determine freezing point of jet fuels, engine coolant and engine concentrate.

• GD-2430 Engine Coolant Freezing Point Testing Equipment is a multifunctional instrument.

II.Main characteristics       

1.  Incorporate style desktop, the structure is compact, sculpt is beautiful.
