The HT-1805 Four in One Gas Detector is a portable multi-gas monitor designed to detect hydrogen sulfide (H₂S), carbon monoxide (CO), oxygen (O₂), and combustible gases. It provides simultaneous monitoring of four gas hazards in a compact handheld instrument, making it suitable for industrial safety, confined-space assessment, maintenance, utilities, oil & gas and other hazardous-environment applications.

3. Detailed Product Description

Product Overview

The HT-1805 4-in-1 Gas Detector combines four gas-monitoring functions into a single portable instrument. It is designed to provide real-time monitoring of H₂S, CO, O₂ and combustible gas (EX) concentrations.

The instrument is intended for applications where personnel need to check atmospheric conditions before or during work in potentially hazardous environments. Audible, visual and vibration alarms alert the operator when gas concentrations reach configured alarm levels.

Its portable design allows the detector to be carried by workers during inspection, maintenance and confined-space activities.

7. Product Benefits

Four-Gas Monitoring

The HT-1805 combines monitoring of H₂S, CO, O₂ and combustible gas in one portable instrument.

Multi-Hazard Detection

Monitoring several atmospheric hazards simultaneously reduces the need to carry separate instruments for each gas.

Multiple Alarm Modes

Audible, visual and vibration alerts provide different ways of notifying the operator when an alarm condition is reached.

Portable Operation

The compact handheld format is suitable for personnel carrying the detector during inspection and maintenance activities.

Digital Display

Gas readings and instrument status can be viewed directly on the LCD.

Data Logging

The data-logging function can support documentation and review of measured gas conditions where enabled by the supplied configuration.

Rechargeable Power

Rechargeable battery operation reduces the need for frequent disposable battery replacement.
