HGT 915 & 917: Gum Test / Thiết bị phân tích hàm lượng nhựa

The Herzog Gum Test Apparatus is designed to measure evaporation residue in aviation fuels, motor

gasolines, and other volatile distillates in accordance with ASTM D 381, ISO 6246, EN 5 and IP 131 test

methods. The HGT 915 uses air evaporation, while the HGT 917 offers the versatility of either air or

steam evaporation. Both models are capable of testing three 100 ml samples simultaneously. Results

indicate the likelihood of induction system deposits and potential sticking of intake valves. Block

temperature is factory set for a temperature of approximately 162oC in air evaporation units and 232oC in

steam evaporation units. The temperature of the evaporation air or steam is controlled by pressure

regulation. Model 917 includes an integral steam super heater as well as a built-in switch which permits

Change over from air to steam evaporation when required.
