Versatility
The user of the PMA 4 is not bound to the standardized test methods only but can adapt the instrument to individual requirements.

Reliable and Precise
The operator has the choice to either apply a gas flame or an electrical igniter.
The gas flame is controlled and if blown off automatically re-lit.
The PMA 4 measures the barometric pressure during the flash and makes an automatic correction.
The temperature indication can be checked using a special probe verification program, in conjunction with a special test lid and a certified thermometer.

Time Saving and Economical to Operate
For samples with a high flash-point the RAPID-heating program heats at an accelerated rate of 8.5 K/min, until 30 K below the expected flash-point, when the heating rate is reduced to the standardized rate of 5 to 6 K/min.
The SEARCH program enables a quick determination of fully unknown samples. The PMA 4 heats the sample at 8.5 K/min and the igniter is automatically applied every 5 K.

Operational Safety
The PMA 4 is equipped with multiple sensors which monitor the proper functioning of this instrument.
One sensor continually checks the performance of the electric igniter. Outside of control limits a warning is displayed.
If gases burn outside the sample cup, it will be detected and signaled to prevent an accident or damage.

PC-Software "FPPnet" (Windows®):
A control & analysis program for easy handling, data storage and program transfer. Providing online display of sample & heater block temperature, gradient (also in an XY-diagram) and test status. Easy to read tableau indicating: sample no., sample name, °C/°F, expected flash point, program, status, found flash point, corrected flash point, corrected rounded flash point. Test results are stored together with all program and device parameters in one file. The simultaneous connection of different petrotest® flash point devices is possible. To simplify the device management they can be named individually.
With the sample changer the software is able to use the result of the previous test as the estimated flashpoint for the next test automatically (important for unknown samples).

pPM - Cup
This is a special test insert with a volume of approx. 15 ml (Milli-Test-Insert).
Although this cup does not comply with the official standards, experiments have shown that in many cases and even with a sample volume of only 2 ml, good reproducibility and test results can be achieved which agree well with those measuring strictly according to the standards.

Fire Extinguisher
The PMA 4 is available with a fire extinguishing option, too.
It requires external Nitrogen- or Carbon Dioxide supply.

Automatic Sample Changer
As an exceptionally time and cost saving alternative,
the PMA 4 is available with an automatic sample changing device.
This carrousel can carrying a maximum of 12 test cups.
