The arc ignition is accomplished with a high-performance ignition coil and two electrodes inside the measuring
chamber close to the surface of the sample.
No gas bottle, no wear out of ignition wire.
Automatic recognition of the flash point:
For the automatic recognition of a flash a new method has been developed. Since the measuring chamber is
completely closed, a pressure increase due to the hot flame inside the chamber can always be assumed. The pressure
increase depends strongly on the size of the flame that originates the big benefit of being able to adjust the automatic
flash detector to the flame size.
Simulation of standard closed cup test methods:
Programming the same test conditions like initial temperature, heating rate and ignition steps and adjusting the value
of introduced air (programmable), MINIFLASH FP(H) VISION can be adjusted to give values close to various standard
methods using a closed cup.
The simulation of open cup methods cannot be expected since these methods suffer from evaporation of the
flammable components.
MINIFLASH FP(H) VISION operates fully automatically. Only the sample has to be filled manually into the sample cup.
MINIFLASH FP(H) VISION is a compact instrument with the illuminated touch-screen display on top of the front panel.
The display leads you through all functions and programming possibilities.
The oven is installed inside the instrument and contains all necessary items for the automatic flash point detection. It
is made out of a circular brass disc of a diameter of 50 mm (approx. 2").
The thermoelectric modules are located above the block. The cooling of the hot side of the elements is done with two
high performance electrical fans. These fans draw in the air from the rear side, so please do not close the air feed on
the back panel.
In the temperature-controlled brass disc two electrodes for the high voltage arc are installed. Do not bend the two
pins to keep the distance in proper length of 2 mm.
To measure the sample temperature, a thermocouple sensor (NiCr-Ni in stainless steel) of 1 mm in diameter is
emerging approx. 14 mm (0.5 ") from the heating block. This sensor is sensitive against bending, so please be careful
not to bend the sensor.
The pressure measurement is outside the hot oven and is connected to the inside of the chamber with a 2 mm
stainless steel cannula and a plastic tubing.
The surface from the oven outside the heat shield should be clean to give a good heat contact to the sample cup. This
surface should be cleaned regularly with tissue paper and some solvent.
