Features & Benefits

  • SMALL SAMPLE: Test can be run with a small quantity of sample (0.15 to 1.5g for small vials, 3.0g for medium vials and 5.0g for large vials, depending on carbon residue content).


  • EASY OPERATION: Test automatically proceeds exactly as prescribed by simply pushing the START switch. Pressure controller (2nd stage regulator) and solenoid valve supply constant pressure. No fine tuning is required after test starts. The buzzer sounds intermittently for 10 seconds when the process is finished.


  • EQUIPPED WITH GAS FLOW METER: With the N2Gas flow meter and needle valve fitted on the front panel, process parameters can be easily checked and calibrated.


  • VINYL LAMINATED TRAP: The condensate trap is equipped on the front of the tester. Thanks to this, the condensate volume is easy to confirm and the trap easily attaches and detaches. Trap jar is vinyl laminated for the safety.


  • EXCELLENT REPEATABILITY/REPRODUCIBILITY: Repeatability and reproducibility are excellent. Since the electronic temperature control is far more precise compared to that of Conradson method’s.
