Gas Indicators and Alarm Systems
Toxic, Combustible and Oxygen Gas Detection with Two-Level Alarm
Model: PE 400
Gas Detectors for Industrial and Confined-Space Safety
Detects combustible, flammable and toxic gases and oxygen depletion. Suited to tanks, pits, vessels, storage bins and oil and gas sites, and for checking air before entry. Gas and range are configured to your requirement.
Enquiring? Share the gas to be detected, measuring range, mains or battery
operation and whether you need data logging, and we will configure the detector around them.

Frequently Asked Questions
It can be configured for oxygen, CO, CO2, SO2, H2S, hydrogen, chlorine, ozone, phosphine, bromine, hydrazine, hydrogen fluoride, propane, CNG/PNG/LPG/natural gas and petrol vapour. The range and resolution are preset for the gas you choose.
Electrochemical, catalytic, infrared and other sensor types are available. The sensor is selected to suit the gas and the application.
Two alarm set points are provided, each with LED indication.
Both options are available: mains operated or with a rechargeable battery.
Accuracy is within ±2%. Detection is by diffusion or suction, depending on the application.
Yes. Data logging is available as an option.
Typical uses are oil and gas sites, tanks, pits, vessels and storage bins. They are used in confined spaces without continuous occupancy and to check for toxic gas before people enter.
