Portable/Pocket Gas Detector (PG Series)
The Portable Gas Detector is a small, handheld device that displays the concentration of respective gas/gases on and LCD backlit screen in %V/V or %LEL or PPM units.
The detectors are designed with two different sensing methods, viz.,
? Diffusion type sensing: Depends on air flow
? Suction type sensing: Draws the sample of the air to the sensors via gas sampling hose.
The portable multi-gas detector are capable of sensing single or multiple gases (2, 4 and 8 gases) simultaneously. The Electrochemical/Catalytic/Pellister/NDIR/PID gas sensors used in PG series generally gives a detection accuracy of ?2% over full scale.
These pocket detectors are well equipped with a password protection facility, buzzer cum vibrator for quick alerts and configurable alarms with two independent set points. An optional data logging of 50000 records with USB interface are add-ons given with this product.
The PG series can be used as a personalised safety equipment for providing localised monitoring and alert. It is widely used by safety managers for performing Process Hazard Analysis (PHA) to identify, comprehend and mitigate the potential risks present at a particular work site. The purpose of handheld gas detectors also includes testing an atmosphere in a confined space before entry for tracing leaks or to give an early warning of the presence of flammable gas/vapour, checking oxygen deficiency when work needs to be carried out in a hazardous area.
