An economy-priced alternative to fully automatic flash-point testers on one hand and a remarkable ease in operation compared to manual instruments on the other hand.

15 Test Methods stored in the PMP 4:

9 standardized methods according to ASTM D 93 meth. A & B & C and ISO 2719 method A & B; each for high or low viscosity samples.

2 RAPID heating programs, which allow examination of samples with a very high flash-point in a time saving and more economic manner. The sample will be heated at a rate of 8 K/min until 30 K below the Estimated Flash-Point when the heating rate is reduced to the standard rate of 5 to 6 K/min.

2 SEARCH modes for quick determination of the expected flash-point of truly unknown samples. The sample is heated with 8.5 K/min and the igniter is automatically applied every 5 K.

2 USER programs very useful because the operator is able to adapt the instrument to his individual requirements. It is possible to set up a special bitumen test where the instrument does not re-cool to ambient temperature but to only +180°C. This saves time and energy.

PMP 4 stores the last 4 program settings under a sample name. This is most convenient if similar products are examined. Just by striking a key, recall the suitable setting from this program library and the apparatus will be prepared for the next test.

Barometric Pressure Correction
The PMP 4 has a built-in pressure sensor which measures the barometric pressure at the place where the flash tests are performed (e.g. in a fume hood and not anywhere in the laboratory). With the cursor on the flash-point temperature, activate ENTER and the corrected flash-point temperature will be indicated.

Easy to manipulate

• Select one of the 15 pre-programmed test methods and enter the Estimated Flash-Point.
  
• Fill the sample into the test cup and insert the temperature probe.
  
• Shift the Test Head into test position, and, if necessary, ignite test flame
  
• Strike RUN-key.

The apparatus now controls the warming up of the sample and also automatically applies the test flame as prescribed by the standard. The operator can fully concentrate himself to the observation of a flash.

Actuating the STOP key terminates the test and the flash-point can be noted from the display

The PMP 4 covers an operating span from approx. +40°C to +360°C (approx. +104°F to +680°F).

If the samples are pre-cooled externally, flash-points can be measured even down to about
+20°C (+68°F).

The reading accuracy will be 0.1 Kelvin.

For reasons of safety, the PMP 4 has an Excess Temperature Protection which will switch off the instrument 20 Kelvin above the previously entered estimated flash-point.
