Gastec MA-2510 Hand Held Flammable Gas Detector - Portable LEL

Description

Gastec MA-2510 Hand Held Flammable Gas Detector – Portable LEL Operational safety begins with accurate detection. The Gastec MA-2510 Hand Held Flammable Gas Detector employs a sophisticated catalytic combustion-type contact sensor to identify various flammable gases other than methane. By drawing air samples through its integrated diaphragm pump, the device provides real-time monitoring of gas levels, ensuring that personnel are alerted to hazardous conditions long before they reach critical limits.

The device is designed for heavy-duty industrial use, featuring a robust housing that is certified explosion-proof. Users can switch between dual measurement ranges, 0 – 25% LEL and 0 – 100% LEL, allowing for both precise low-level leak detection and general concentration monitoring. Although this specific model has been discontinued, its legacy of reliability continues to make it a benchmark for analog flammable gas detection technology.

Features

Manual Operation: Requires no batteries or power source. It utilizes a precision hand-operated piston pump to draw a consistent air sample through a chemical detector tube, ensuring readiness in any environment.
Detector Tube Precision: Works with Gastec’s dedicated #251 detector tube for flammable gas (LEL) to provide selective and quantitative measurement of combustible gases like methane, propane, and other hydrocarbons.
Direct LEL Readout: The concentration of flammable gases in the sample air is displayed as a percentage of the Lower Explosive Limit (%LEL) via a distinct color stain length on the calibrated tube, offering clear and immediate visual results.
Intrinsically Safe Design: Being completely non-electronic, the detector is inherently safe for use in potentially explosive atmospheres without risk of spark ignition.
Lightweight and Durable: Housed in a robust plastic case with an integrated pump and tube tip breaker, it is highly portable, easy to carry, and resistant to field conditions.
Fast and Simple Operation: Provides results within 1–2 minutes, enabling rapid decision-making for leak detection, confined space entry checks, and emergency assessments.

Applications

Gas Leak Detection and Pinpointing: Ideal for checking suspected leaks in natural gas pipelines, LPG installations, industrial gas lines, and residential gas appliances.
Pre-Entry Confined Space Testing: Essential for atmospheric testing before entering tanks, sewers, manholes, silos, and other confined spaces where flammable gases may accumulate.
Industrial Safety Inspections: Used in refineries, chemical plants, manufacturing facilities, and mining operations for routine safety audits and hazard assessments.
Emergency Response and Incident Investigation: Provides first responders with a quick way to evaluate flammable gas levels during emergencies, spills, or accidents involving combustible materials.
Utility and Maintenance Work: Trusted by plumbers, HVAC technicians, and facility engineers to verify gas-free conditions before performing repairs or installations near fuel systems.
