"Simple to use interface –digitally computer control of all instrument functions Standard ASTM D5001 test sequence pre-loaded into ABT microprocessor controller – operator fits cleaned specimens, adds fuel sample & presses the ‘Start Test’ button. Automatic control of test sequence-no operator-included variability in test results. Automatic flow controllers for moist and dry air-no operator input required to control the humidity and flow rate of the conditioned air. PC based data logging of Motor speed, test duration, fuel temperature, air temperature, humidity recorded during the test & a summary printed out confirming that all parameters were within the specified limits. Interchangeable humidity & temperature probes-humidity and temperature measurement does not need to be re-calibrated-simply replace the combined relative humidity and temperature probe with an exchange pre-calibrated unit. Heating & Cooling System through Peltier Heating & Cooling System Digital Microscope with Image Acquisition System & software PC based data acquisition & analyze system of motor speed, test duration, fuel temperature, air temperature, humidity.
