Portable O2 Detector low ppm measurementatex-explosion-image

Low ppm range detection and measurement of O2 (gas), in confined space, gas samples, Ex proof certified, with Large LCD Display, alarm, vibration, battery operated, light weight
Model: SG Series

Handheld type, battery operated Portable O2 ppm Detector for low concentration ppm range measurement of oxygen in ambient air or confined space.

Oxygen is not only life sustaining gas but also support fire. Many times, it is required to maintain very low concentration or no oxygen in the target area. Hence, it is necessary to detect and measure oxygen level in ppm terms, rather than % vol range.

SG series portable O2 detector is light weight, battery operated handheld device. The detector is ideal instrument for quick low ppm oxygen detection in range of 100 ppm or 2000 ppm. It is equipped with large LCD display for measurement readout. It also has alarm with sound and flashing light, vibration for alert.
