Gas leak detector LOGO-Tools CD-100 (RIDGID), handheld combustible gas detector

The LOGO-Tools CD-100 (RIDGID) is a handheld combustible gas leak detector designed to locate flammable gas leaks quickly and reliably. This portable probe-style instrument senses the presence of combustible gases near pipelines, fittings, valves and appliances and provides audible and visual alerts to help the operator identify leak sources during inspection and maintenance tasks. The CD-100 is intended for field use in HVAC, gas fitting, maintenance and emergency response situations where rapid detection of leaking hydrocarbons or natural gas is required.

Advantages

The detector combines a sensitive sensor element with a compact probe for access to confined spaces and typical utility connections. Its handheld format and intuitive controls enable single-person operation and fast sweep testing around joints and seals. Audible and visual indicators give immediate feedback on gas concentration trends, supporting targeted inspections and reducing the time needed to find leaks. The unit is battery-powered for portable use and built for routine field handling.

Suitable for

• Detecting leaks on natural gas and other combustible gas pipelines
• Inspection of domestic and commercial gas appliances and fittings
• HVAC service and maintenance where gas detection is required
• Emergency response and safety checks following odour reports

Key specifications

• Handheld probe-style instrument for point detection
• Sensitivity suitable for locating combustible hydrocarbon gases and methane
• Audible alarm and visual indicator for concentration trends
• Battery-powered operation for portable field use
• Compact, lightweight design for access to tight areas

How to use

Switch on the unit and allow the sensor to stabilise as indicated by the manufacturer’s warm-up procedure. Move the probe slowly along pipe runs, around joints, valves and appliance connections while observing the visual indicator and listening for audible alerts. When the detector indicates elevated gas levels, hold the probe steady to confirm the reading and trace the direction of the strongest signal to locate the leak source. Power off the instrument after use and replace batteries as recommended.

Usage recommendations

For reliable detection, perform a sensor warm-up before measurements, keep the probe clean and avoid rapid sweeping motions that can mask localized leaks. Use the detector in well-ventilated conditions when possible and follow applicable safety procedures when a leak is suspected. Regular functional checks and battery replacement ensure consistent performance during inspections.
