Gas detector

Single gas detector XDB-XX

First, single gas detector features:

1, the use of lattice liquid crystal display, directly display the measured gas concentration.

2, this instrument is a safety equipment, explosion-proof mark Exib I, can be used in flammable and explosive dangerous environment.

3, the alarm point can be set according to user requirements, with high alarm point, low alarm point, TWA alarm point, STEL alarm point.

4, with 2 bright alarm lights. 1 charging indicator,

5, the use of rechargeable battery, after each charge, continuous working time is more than 300 hours.

6. Crocodile type back clip is adopted to effectively prevent the instrument from falling. Also equipped with a leather case.

Note:

1, the above detection range of units “ × 10-6” Equivalent to the International Unit of measurement (ppm). For example: (0 to 100)× 10-6”  Equal to (0 ~ 100)ppm.

2, the above table only lists the usual range of gas measurement, if you need other ranges, can be customized.

3, no listed units default to 1× 10-6.
