The Gasman is a portable single gas detector designed for reliability and impact resistance in harsh environments. Its construction ensures exceptional durability and shock resistance, with an IP65 protection rating. The Gasman supports a wide range of detectable gases and offers six combustible gas calibration options. Featuring a loud alarm and bright visual indicators, it is ideally suited for industries such as oil and gas, chemical, steel plants, wastewater treatment, and public water supply.
Features a scratch-resistant polycarbonate casing with excellent anti-electromagnetic interference (EMI) properties, ensuring reliable operation and safety in harsh environments.
Rated IP65 for protection against dust and low-pressure water jets.
Constructed using a synthetic rubber overmolding process for enhanced durability.
Multi-Stage Alarm Systems
A 95-decibel audible alarm, combined with a two-stage instantaneous alarm system and TWA (Time-Weighted Average) alerts for toxic gas exposure, ensures prompt evacuation in hazardous situations.
A red/blue visual alarm and a built-in vibration alarm provide clear warnings even in high-noise environments.
Detection Capabilities & Power Configuration
Suitable for detecting flammable gases, oxygen, and toxic gases.
Rechargeable lithium-ion batteries are compatible with detectors for all gas types.
Non-rechargeable batteries are approved for use only in toxic gas and oxygen detectors.
Operation & Display
Real-time display of TWA concentration and peak (STEL) values (selectable).
Smart, user-replaceable sensor modules.
One-button operation for simplicity and ease of use.
A backlit LED screen clearly displays instrument status for easy reading.
Ergonomic Design
Ultra-lightweight design.
