Multi-Gas Portable Detectors
T4, T4x, Gas-Pro, Tetra 3 and DuoIQ detectors for flammable gas, oxygen, H2S, CO and more.
The T4 detects the four most common gas hazards — carbon monoxide, hydrogen sulphide, flammable gases and oxygen depletion — in one rugged unit, drop tested to 4 m and sealed to IP65 and IP67, with a battery life of more than 18 hours. Its TWA Resume function keeps toxic exposure calculated correctly across a shift even if the detector is switched off for a break. The Zone 0 approved T4x adds MPS flammable and long-life oxygen sensor options, which remove the risk of sensor poisoning and extend runtime beyond 35 hours.
Gas-Pro monitors up to five gases with a top-mount display, an optional internal pump and a dedicated pre-entry check mode for confined spaces. Specialist versions cover harder duties: Gas-Pro IR measures hydrocarbons by infrared, even in low-oxygen atmospheres; Gas-Pro PID detects hundreds of volatile organic compounds; and Gas-Pro TK uses a dual-range infrared sensor that auto-ranges between %LEL and %volume for inerted tanks. Tetra 3 is a compact diffusion detector with an extended gas range, and DuoIQ is a dual-gas monitor with modular sensors and Bluetooth connectivity.
