Online Gas Detection System (V- 810)

This system has a wall mount case incorporating indicator units and an alarm unit of the V Series/V2 Series

Outline

V-810 gas detector is compact system of well(panel) mount type with combines indicator units, an alarm unit, and various gas detector heads of the V series
Detectors combustible gases, toxic semiconductor manufacturing gases, and oxygen(oxygen deficiency) and gives an alarm signal when the gas concentration goes over a set value (or under a set value for oxygen deficiency), so as to prevent disasters such as gas explosion, poisoning and oxygen deficiency
VB- 810 incorporates a backup power supply unit

Features

Compact design.
Standard cases for 3/6/9/12/15/18/21 points are available
Wide variety of input power sources
Can be equipped with a Zener barrier
2-stage alarm is also available
Combination of the V series/V2 series unit allow detection of and alarm for various gases
