Koehler Instrument K33780 / K33781 Petroleum Gum Residue Tester

Product Description
The Koehler K33780 Existent Gum Evaporation Bath is a three-unit bath without built-in super-heater. All controls are housed in the bath cabinet. It evaporates aircraft turbine fuel and motor and aviation gasoline samples under controlled conditions in accordance with ASTM specifications. Tester consists of a high temperature evaporation bath with 100mL test beakers. For aircraft turbine fuels, a steam generator and steam super-heater would also need to be ordered - request pricing on this model.

Electrically heated baths for determining existent gum in aircraft turbine fuels by steam-jet evaporation and in motor and aviation gasolines by air-jet evaporation. Fully insulated, aluminum block design assures safe, efficient high temperature operation. Tester is equipped with air/steam pressure regulator with gauge and a flowmeter for adjusting air flow per ASTM specifications. Stainless steel jets deliver air or steam flow to the test wells through removable brass conical adapters. Microprocessor PID control provides quick temperature stabilization without overshoot, and the bath is protected by an over-temperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and set-point temperature values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options.
Maximum Temperature: 475°F (246°C)
Temperature Control Stability: ±1°F (±0.5°C)
Bath Configuration: Machined aluminum block with multiple cartridge heaters
Heater Range: 0-1500W
