The post Crowcon Detective+ Multi Gas Monitor appeared first on Adex.
]]>Rugged and robust, Detective+ features either fixed or folding legs and a protective frame that allows stacking for easier storage.
Available with an optional internal pump for sampling versatility, alarms are announced with an extremely loud sounder, while multiple beacons ensure 360 degree visibility.
Detective+ may now also be equipped with infra-red (IR) sensors, providing either CO2 detection, or allowing higher levels of flammable gas monitoring. IR sensors also provide immunity to the poisoning effects which standard flammable gas sensors can suffer from. This extends sensor life and further increases measurement confidence in tough applications such as water treatment plants and certain chemical or hydrocarbon processing facilities. Detective+ can be specified with a wide range of sensors, including hydrogen, to monitor a wide range of gases which pose a variety of threats.

- Auto-ranges switch between %vol and %LEL measurement, so always operating to the correct parameter.
- Measures gas in high %vol as well as %LEL concentration, which single IR sensors can’t
- Isn’t inhibited by high hydrocarbon concentrations unlike catalytic bead sensor
Gas-Pro TK keeps you up-to-the moment with oxygen concentrations in the tank; telling you when the oxygen levels are;
- Low enough to load and store fuel safely;
- High enough for safe tank entry.
Tanks can be sampled quickly from their top, middle or base, due to an integrated pump which draws samples through a line up to 30m long.
Offering detection of up to five gases in a compact and rugged solution, Gas-Pro TK has an easy-to-read top mount display, combining ease of use and user focused features. At 340g, it is light enough to clip to your belt or overalls, so it easy for the technician to keep with them during their working day.
Personal protection monitor
Gas-Pro TK is an extension of the Gas-Pro range. Therefore, in addition to its superb tank check capabilities, it also offers the full personal gas detection and confined space pre-entry check functionalities provided by other Gas-Pro detectors.

]]>The post Crowcon Gas-Pro IR Multi Gas Detector appeared first on Adex.
]]>The infrared measurement gives improved reliability and measures gas in two different wavelengths: one that absorbs gas and the other does not. With little chance of being poisoned, the Gas-Pro IR personal multi gas detector is inherently safer and saves the need of regular and expensive pellistor replacement when used in likely contaminated environments.
The Gas-Pro personal multi gas detectors are known for their simple use and functionality as well as easy testing and calibration. The Gas-Pro IR now completes the Gas-Pro range and gives greater flexibility for sensor selection in this 5-gas multigas detector.
IR Technology
Infrared emitters within the sensor each generate beams of IR light . Each beam is of equal intensity and is deflected by a mirror within the sensor on to a photo-receiver, which measures the level of IR received. The “measuring” beam, with a frequency of around 3.3μm, is absorbed by hydrocarbon gas molecules, so the beam intensity is reduced . The “reference” beam (around 3.0μm) is not absorbed, so arrives at the receiver at full strength.
The %LEL of gas present is determined by the difference in intensity between the beams measured by the photo-receiver.
IR sensors are reliable in some environments that can cause pellistor-based sensors to function incorrectly or in some cases fail:
- In some industrial environments, pellistors are at risk of being poisoned or inhibited. This leaves worker on their shift unprotected. IR sensors are not susceptible so significantly enhance safety in these conditions.
- Exposure to high levels of flammable gas can cause “sooting” of pellistors, reducing their sensitivity and potentially leading to failure Pellistors require oxygen to function. However, IR sensors can be relied on in applications such as fuel storage tanks where there is little or no oxygen, due to flushing with inert gas prior to maintenance or which still contain high levels of fuel vapours.
- The fail-safe nature of IR sensors, which automatically alert you to any fault, provides an additional layer of safety.
Gas-Pro IR measures in %LEL and has been certified for use in hazardous areas as defined by both ATEX/IECEx and UL.

Gases and Ranges
Ranges and alarms vary by country and application; these can be configured as required. Each channel can have two instantaneous alarms. Toxic channels also have TWA alarms. Flammable gas calibration is available for methane, propane, butane, pentane, hydrogen and ethylene as standard.
| Gas | Range | Typical Alarms |
| Flammable | 0-100% LEL | 20% LEL |
| Oxygen (O2) | 0-25% | 19/23.5% volume |
| Hydrogen Sulphide (H2S) | 0-100ppm | 5ppm |
| Carbon Monoxide (CO) | 1-500ppm | 30ppm |
| Sulphur Dioxide (SO2) | 0-20ppm | 1ppm |
| Ozone (O3) | 0-1ppm | 0.1ppm |
| Ammonia (NH2) | 0-100ppm | 25ppm |
| *Carbon Dioxide (CO2) | 0-5% | 0.5 % volume |
| Carbon Monoxide (CO) H2 compensated | 0-500ppm | 30ppm |
| Hydrogen Cyanide (HCN) | 0-30ppm | 10ppm |
* T3 is available in a safe area CO2 version offering 0-5% carbon dioxide measurement.
The CO2 sensor replaces the flammable option and can be supplied with oxygen and toxic sensors.
