Gas Leak Detector for Methane and Propane
Checking carbon monoxide levels is as easy as pushing just one button with the Extech C010. This meter can measure CO levels up to 1,000 ppm with a resolution of 1 ppm and ±5% or ±10 ppm basic accuracy (whichever is greater). The CO10 sounds an alarm starting at 35 ppm that increases in speed at higher concentrations of CO. Above 200 ppm, the alarm will sound continuously. Additional features include a backlight on the display that can be used in low light areas, max hold, data hold, and auto-power-off. The meter comes complete with a 9-volt battery, protective holster, and case.
The Extech CO100 is a desktop indoor air quality CO2monitor that measures carbon dioxide concentrations (CO₂) from 0 to 9,999 ppm, air temperature from -5°C to 50°C (23°F to 122°F), and humidity from 0.1 to 90% RH. It comes with a user programmable visible and audible CO2 warning alarm. The meter has a maximum/minimum CO2 value recall function. The CO100 is complete with a maintenance free NDIR (non-dispersive infrared) CO2 sensor and a universal AC adaptor.
Check CO levels up to 999ppm with the push of a button using Model CO15. An audible alarm indicator will continuously beep starting at 25ppm (preset warning level - value can be adjusted) and the display will flash until the CO level goes down to normal range. A backlight on the display can be used for low light areas. The meter comes complete with batteries, wrist strap, and pouch.
CO210 is a Desktop Indoor Air Quality CO2 Monitor/Datalogger. Measurement ranges are 0 to 9,999 ppm (CO₂), 14 to 140°F (-10 to 60°C) for Air Temperature and 0.1 to 99.9% for Relative Humidity. It features Minimum/Maximum CO2 value recall, Year/Month/Date/Time display, and an Automatic Baseline Calibration (minimum CO2 level over 7.5 days) or manual calibration in fresh air. Comes with AC adapter and user manual.
The Extech CO220 air quality CO2 monitor measures carbon dioxide, air temperature, and humidity. The CO220 also calculates dew point and wet bulb. Use in conference rooms, schools, greenhouses, factories, hotels, hospitals, and any place where high levels of carbon dioxide are generated. It calculates statistical weighted averages of TWA (8 hour Time Weighted Average) and STEL (15 minute Short Term Exposure Limit). Maintenance free NDIR (non-dispersive infrared) CO2 sensor. It can manually store/recall 99 readings. Complete with AC adaptor.
The Extech CO260 monitors indoor air quality for carbon monoxide (CO) and carbon dioxide (CO₂) levels. In high concentrations these gases can affect the health and well-being of people and pets. Monitor CO₂ levels in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines, and anywhere that high levels of carbon dioxide may be generated. The CO260 also measures air temperature/relative humidity and calculates dew point/wet bulb temperatures. It can datalog manually up to 99 readings with internal memory or continously up to 32K readings with included software.

Multi-spectrum IR flame detector specifically designed to detect both hydrocarbon AND hydrogen flames — hydrogen flames are nearly invisible and emit primarily in the UV (poor for IR-only detectors), so most IR detectors miss them. The 975HR's specialized IR sensor mix catches hydrogen-flame radiation that the 975MR misses. Critical for hydrogen-production plants, refineries with hydrogen reformers, fuel-cell manufacturing, and any process where hydrogen is present alongside hydrocarbons. SIL 2 prior-use FMEDA.
Multi-spectrum IR flame detector with QuadSense IR3 technology — analyzes the multi-spectral signals of hydrocarbon gas or liquid fires using four separate IR sensors. Detects a 1 ft² (0.1 m²) gasoline pan fire at 300 ft (90 m) — among the longest detection ranges in the 975 family. Best for outdoor large-area coverage (LNG terminals, petrochemical units, offshore platforms) where a single detector replaces multiple shorter-range UV/IR detectors. SIL 2 prior-use FMEDA.
Ultra-fast UV/IR flame detector — detects fire in under 20 milliseconds using a unique dual sensor with selectable UV and IR channels. The fastest detector in the 975 family — built for explosion-suppression and rapid-response fire-control loops where a 100 ms standard detector is too slow (munitions, propellant manufacturing, high-pressure hydrogen storage, fuel-mix piping). UV and IR channels can be used separately or combined for application-specific false-alarm rejection. SIL 2 prior-use FMEDA.
Dual-spectrum UV/IR flame detector — senses radiant energy in both the short-wave UV and short-wave IR portions of the spectrum simultaneously, providing high false-alarm immunity (welding, lightning, sunlight reflection) while detecting hydrocarbon-based fuel and gas fires. The workhorse 975 variant for general process / refining / petrochemical fire detection. SIL 2 prior-use FMEDA. Variable-area coverage from a single detector reduces installed sensor count vs. older single-spectrum detectors.
Smart sensor module that pairs with the Rosemount 928 Wireless Gas Monitor — tool-less hot-swappable design lets a technician replace the sensor module in the field without breaking the wireless connection or recalibrating. Available for H₂S, CO, O₂, and combination gases. Each 628 ships pre-calibrated and includes a quick-connect IP filter. Best when an installed 928 base needs to swap from one gas type to another (e.g., switching a perimeter monitor from H₂S to CO during seasonal process changes).
WirelessHART-powered gas monitor — detects H₂S, CO, and O₂ depletion in remote applications previously too costly to monitor with wired sensors. Pairs with the Rosemount 628 Universal Gas Sensor (tool-less hot-swappable smart sensor module). Eliminates conduit and trenching — typical install is 30 minutes vs. days for wired equivalents. SmartPower battery; 5-year operating life under typical update rates. IP66 with the Ingress Protection filter on the 628. Best for tank-farm leak monitoring, perimeter-fence early warning, and confined-space pre-entry surveillance.
