|K33700 Existent Gum Evaporation Bath & Data Acquisition Software|
Gum formed during fuel storage can deposit on induction system surfaces, intake valves, stems and guides. To test for gum content, a 50mL sample is evaporated in an aluminum block bath for a specified period under controlled conditions of temperature and flow of air (aviation and motor gasolines) or steam (aircraft turbine fuel).
Features and Benefits

|K33700 Existent Gum Evaporation Bath|
|Evaporates aircraft turbine fuel and motor and aviation gasoline samples under controlled conditions in accordance with ASTM specifications. Consists of a high temperature evaporation bath with 100mL test beakers and, for aircraft turbine fuels, a steam generator and steam superheater.
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. 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 overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information.
Model K33800 with Built-in SuperheaterSix-unit bath with a built-in thermostatically controlled superheater which delivers dried steam to the bath inlet for steam-jet method testing of aircraft turbine fuels. Has digital-indicating solid state bath temperature control with digital setpoint and display.

|K33700-SFW Existent Gum Software|
|Existent Gum Software
retrieves temperature data in real-time and performs data analysis for
up to 6 samples at one time. The data analysis also includes accounting
for the tare beaker as well as calculations for residue and gum content
for both washed and unwashed gums. Direct communication with the Koehler
analytical balance eliminates weighing errors by recording values directly
from the balance with a simple click of the mouse. The sophisticated Windows®-based
software package features an easy-to-navigate operation, a straightforward
user interface, minimal draw on Windows® memory resources, automatic
real-time data acquisition via RS232 connection, and a timer / stopwatch
feature for general laboratory use. The "test intelligent" software
simplifies the testing process by providing sequential test prompts for
assisting the operator with each step of the test procedure. The active
zoom, pan, and trace feature allows the ability to change axes and the
magnification of any sector of the pressure or temperature graphs to view
data in greater detail. The final test data is exported with graphs and
test parameters either directly to Microsoft® Excel, in ASCII file
format for use with LIMS or any other spreadsheet programs, or directly
to a printer with a test report according to ISO guidelines. Test data
is saved in a database format for determining test averages, standard
deviations, and ASTM test repeatability for aviation turbine fuels, aviation
gasolines, motor gasolines washed and unwashed. The software package requires
no PC hardware installation and includes the software installation CD
and computer connection cables.
