Rubber test apparatus GHT 915/917

Simple and safe quality control for jet fuels and gasoline

Herzog's rubber test apparatus is designed to measure evaporation residue in jet fuels, engine gasoline and other volatile distillates according to ASTM D 381, ISO 6246, EN 5 and IP 131 test methods. Model HGT 915 uses air evaporation, while model HGT 917 offers air or vapour evaporation versatility. Both models are able to analyse three 100 ml samples simultaneously. Results indicate the induction system build-up probability and suction valves jam potential.

Block temperature is factory set for a temperature of about 162 °C in air evaporation units and 232 °C in vapour evaporation units. Evaporation air or vapour temperature is controlled by pressure regulation. Model 917 includes an integrated vapour super heater, as well as an integrated actuator which allows to switch from air evaporation to vapour evaporation, as necessary.

Features

  • Three easily accessible test stations
  • Choice for air and air or vapour evaporation.
  • Aluminium heater block with electronic thermal control Integrated vapour super heater (only HGT 917).
  • Includes beaker, shielded thermometer and precision pressure gauge
