Existent Gum Tester
-ASTM D381
-Determine aviation fuels,aviation gasoline and motor gasoline

Existent Gum Tester Model: SLH -8019B

Summary
This instrument is designed and made as per standards GB/T 8019-2008 Standard test method for gum content in fuels by jet evaporation and ASTM D381. It can be used to determine the existent gum content of aviation fuels by steam vaporizing medium.
Equipping with an air compressor, this instrument can also be used to determine the existent gum content of aviation gasolines and motor gasolines by air vaporizing medium.

I. Main technical features
1. It equips a specially designed heating bath.The gas circuit is designed reasonably and the effect of
evaporation is good.
2. The material of working bench is stainless steel. It has 3 sample wells. A pressure gauge shows the
flow rate when steam vaporizing medium is used. A ball float type flowmeter shows the flow rate
when air vaporizing medium is used. It can determine 3 samples at a time.
3. The instrument is desktop structure. Simple design and easy to operate.
