KI-33700 Existent Gum Evaporation Bath & Data Acquisition Software |
| Test Method 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 • Conforming to ASTM D381 and related specifications • Choice of three-unit and six-unit models • Available with built-in steam superheater • Microprocessor programmable high accuracy temperature control • Built-in pressure regulators and air flowmeters |

KI-33700 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 PSSC representative for information. Model KI-33800 with Built-in Superheater–Six-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. Model KI-33700–Six-unit bath without built-in superheater. Controls are housed in a separate cabinet connected to the bath by multi-conductor cable. Model KI-33780–Three-unit bath without built-in superheater. All controls are housed in the bath cabinet.

KI-33700-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. Computer Requirements PC Processor: Intel® Pentium II or similar (minimum) Processor Speed: 500 MHz or higher Operating System: Windows ® 98 SE, 2000, NT, ME, XP Memory (RAM): 64 Mb RAM (128 Mb RAM recommended) Hard Disk Space: 15 Mb free space (minimum) Communication Ports: one or two RS232 ports Other Software: Microsoft ® Excel (97 or above) For a complete demonstration of the Existent Gum Software Package and its capabilities, please download a copy of the demo version (5.6MB file). After installing the demo software, you will be prompted to quickly register the demo with Koehler via email. Click here to download the software demo. |
