ASTM D381 Existent Gum

ASTM D381 Existent Gum  is  very importer in the  laboratory equipment .This instrument is designed and made as per standards GB/T 8019 Standard test method for gum content in fuels by jet evaporation and ASTM D381 Standard test method for gum content in fuels by jet evaporation.

GD-8019A ASTM D381 Existing Chewing Gum Content Device and Gum Content Tester in Jet Fuel Evaporation

Introduction:
GD-8019A ASTM D381 Existing chewing gum content device is designed and made in accordance with the standard GB/T 8019 Standard Test Method for Gum Content in Fuel Jet Evaporation and ASTM D381 Standard Test Method for Gum Content in Jet Fuel Evaporation. It is suitable for determining the presence of the content of aviation gum in gasoline and engine gasoline (not suitable for determining in the presence of chewing gum content of aviation fuel in engines)

I. Main technical features :
1. ASTM d381 chewing gum tester provides specially designed heating bath. Gas circuits are reasonably designed and the evaporation effect is good.
2. The material of the work bench is stainless steel. It has 5 sample holes. Each jet flow can be adjusted and controlled by an independent flowmeter. It can do 1~4 decisions at the same time.
3. Chewing gum content desktop structure test. Simple design and easy to operate. It equips the air compressor to make it meet the standard requirements.
4. Each puncture tester equips a unique flowmeter. It can properly control the hot air flow rate from each test hole.
