Leading gas sensing solutions supplier in China!

Note:

①The measuring range within 20-2000sccm is available and regular measuring ranges such as 20,

30, 50, 100, 200, 500, 1000, 1200, 2000sccm.Customized fee will be charged for other ranges.

②sccm means standard-state cubic centimeter per minute. Standard-state: gas temperature is

0℃ and pressure is 101.325 kPa.

③The testing environment is room temperature and clear air.

④The pressure range of 0.8 MPa can be customized.

⑤The temperature compensation is for the tem. range of 0-50℃ and the compensation

performance can’t be ensured beyond the temperature range.

Calculation for Airflow

Actual flow=full scale * (sensor actual output voltage-zero output voltage) / (full scale output

voltage-zero output voltage)

For example: the sensor full scale is 1000 sccm, the sensor zero output voltage is 1V and full scale

output voltage is 5V, and the actual output is 2.5V.

So, the actual flow=1000sccm * (2.5V - 1V)/(5V- 1V) = 375sccm

Naming Rule

F1 0 1 2 - □- □- □

Cautions

1. Prohibit to use it in strong corrosive gas, toxic gas, explosive gas environment.

2. If measured gas medium contains dirt, the sensor’s lifespan will be shorten. We suggest users equip

the sensor flow inlet with 5 micrometer precise filter.

3. The sensitivity of the product will reduce or be damaged if it contacts to water.

4. The wrong connecting of power supply will damage the internal circuit.
