YJJ PGM-2500 Portable Four-One Wireless Gas Detector Used For Gas Monitoring Hazardous Environments

Features:

PGM-2500 is a four-in-one portable gas detector under the QRAE 3 series of the American company Hua Rui. It is not a traditional analyzer. It comes in two versions: pump suction type and diffusion type. The core function is to simultaneously detect various gas concentrations to ensure personnel safety. It is widely applicable to industrial and fire safety scenarios. The following is the detailed parameter and usage introduction of it: Core parameters

Main application
This detector, with its portability, multi-gas synchronous detection and wireless transmission advantages, is mainly used for personnel safety protection in hazardous environments. Specific scenarios are as follows:
Petroleum, petrochemical and chemical fields: During oil extraction, refining and chemical production processes, there are easily leaked combustible gases, hydrogen sulfide and other toxic gases. The detector can monitor the concentration in real time, and give an alarm when the concentration exceeds the limit, avoiding explosion and poisoning accidents; it is also suitable for gas detection before confined space operations to ensure the safety of workers entering enclosed equipment, underground pipelines, etc.
Firefighting and emergency response: At fire scenes, "toxic twin gases" such as carbon monoxide and hydrogen cyanide are often produced. This device can quickly detect the concentration of such gases, providing a safety warning for firefighters; in emergency rescue, it can also be used for gas detection at leakage accident sites to assist in formulating rescue plans.
Industrial and environmental protection fields: In production processes of metallurgy, pharmaceuticals and other factories, there may be gas leakage risks, which can be used for daily safety monitoring in workshops; in environmental protection scenarios, it can sample and detect the gas concentration around contaminated sites and exhaust outlets, assisting in environmental quality assessment and pollution control.
Other scenarios: In scenarios such as telecommunications well operations, gas pipeline maintenance, etc., it can detect the oxygen content in the working environment (to prevent oxygen deficiency) and the concentration of combustible gases in advance, avoiding accidents during operations; it is also suitable for daily monitoring of gas concentration in places with sensitive gas concentration requirements such as gas stations and laboratories.
