Specifications

1.Built-in pump can inhale gas ten meters away
2.audible and visual alarm
3.Big screen , character display, instantaneous valu

Feature:

PG-M4+ gas detector can detect one, two, three, or four kinds of gases (that’s two-in-one, three-in-one, four-in-one). It uses sensors for oxygen, combustible gas or toxic gas.

PG-M4+ gas detector has built-in pump.

PG-M4+ gas detector has large LCD screen, audible and visual alarm hint. It can detect dangerous gas in complex work environment and alert people in time.
