Instrument structure and components

The overall structure of the instrument is as follows:

1 Touch screen: 8-inch 800 * 600 true color touch screen

2 Lifting mechanism

3 Fire sweeping mechanism

4 L-type armored platinum resistor

5 Ignition platinum wire

6 Test cup

7 Printer

Instrument rear view

1 Serial communication port, RS 232 Level

2 Fan outlet

3 Electric furnace fan outlet

4 Power cord

5 Safety seat

6 Power switch

 Lifting mechanism

l Stepper motor drive, automatic control mechanism lifting.

1.Flash point detection system

l The ignition wire of platinum alloy is controlled by the program of small voltage and high current.

l The fire sweeping mechanism is driven by a stepping motor and swept through the test cup in a straight line.

l The flash fire detection sensor adopts optical sensitive sensor to detect the flash point in a non-contact manner.

2.Sample temperature sensor

l The sample temperature sensor adopts armored L-type PT100 to measure the temperature of the sample in the test cup.

l When adjusting the height of the sensor, loosen the nut fixing the temperature sensor. Adjust the position exactly at that time and then tighten it.

3.Heating system

l AC 220V voltage supply, two 300W heating rods (two are available, installed to the instrument), 0-600w can be adjusted continuously.

l The other two heating rods can be switched in the system settings.

l The heating system has a high-power cooling fan, which can set the cooling temperature of the hot bath in the method setting.

4.Fire fighting device

    The instrument is equipped with fire extinguishing cover. Only when the detection of ignition point is over, the sample starts to burn. At this time, the lifting mechanism rises, and the fire cover is driven by the stepping motor to extinguish the burning sample cover.

5.Barometer

In the instrument cabinet, electronic barometer is used.

6.Printer

In front of the instrument, a thermal micro printer is used, and the printing paper must be thermal printing paper.

III. Install

l The automatic open flash point tester should be installed in the laboratory with good ventilation device or in the laboratory or fume hood close to the fume hood, so as to timely eliminate the toxic gas in the measurement process, and ensure the safety and non-toxic of the operator.

l Insert the power cord of the instrument into the power socket behind the body, and the other end into the 220V AC power socket.Power on to work.

l The grounding is required to be good, and the power supply shall meet the needs of the instrument.
