Portable Gas Leak Detector install base HT61 — Methane sensor, 10% FS range, handheld

The install base HT61 is a portable gas leak detector designed specifically for methane detection with a 10% FS measurement range. This handheld, battery-powered instrument offers rapid response to changes in methane concentration and is intended for use in residential, commercial and light industrial environments. Its compact size and straightforward controls make it suitable for routine maintenance checks, safety inspections and emergency leak localization where quick, on-the-spot readings are required.

Advantages

The HT61 provides a focused methane sensing capability within a 10% FS range, delivering fast audible and visual alerts to help operators identify leaks quickly. Battery operation and a handheld form factor allow for portable use in confined spaces and across multiple sites without dependence on mains power. The device features simple user controls and an ergonomic design for extended handheld use during inspections and response tasks.

Suitable for

• Locating methane leaks in domestic gas installations and appliance connections
• Routine safety inspections in commercial buildings and retail facilities
• Maintenance checks and leak surveys in light industrial sites and workshops
• Emergency response and rapid on-site leak verification

Key specifications

• Target gas: Methane (CH4)
• Measurement range: 10% of full scale (FS)
• Form factor: Handheld, portable
• Power: Battery-powered for field use
• Outputs: Audible and visual alarm indicators for rapid detection
• Typical use environment: Residential, commercial, light industrial

How to use

Power the unit with the appropriate batteries and verify operational readiness according to the built-in power and status indicators. Move the probe or sensor tip slowly along joints, fittings and appliance connections where methane may escape, paying particular attention to hidden pipework and valve assemblies. Observe the display and alarm outputs; when the device signals elevated methane levels, mark the location and take appropriate isolation or ventilation measures. Follow local safety procedures for ventilating the area and notifying qualified personnel when a confirmed leak is present.

Usage recommendations

Perform a functional check before each inspection, allow the sensor to stabilise after powering on, and replace batteries or service the sensor according to the manufacturer’s maintenance schedule. Avoid using the detector in atmospheres outside its specified temperature and humidity ranges and keep the sensor clean and free from contamination to ensure accurate response to methane. For confined-space work or major leaks, combine detector readings with appropriate safety equipment and trained personnel.
