Combat occasional risks posed by flammable gases
A low-cost alternative to specialist devices which are certified for use in explosive atmospheres, Flamsafe-4/20 is an uncertified detector suitable for "everyday" environments
Custodian CDL can be specified with sensors for flammable gas, oxygen and one or two toxic gases.
Flammable gas sensors can be calibrated for methane, propane, butane or pentane, while users wishing to minimise maintenance can opt for a long-life oxygen sensor lasting two years.
Sensors for all common toxic gases are available, including carbon monoxide, hydrogen sulphide, sulphur dioxide, ammonia and chlorine.
A high-contrast, backlit display automatically scrolls between readings for each gas channel.
Peak levels are displayed on request, and time-weighted averages for toxic gases can be recalled.
If a hazard is detected, a wailing siren (85dBA at 1m) is triggered along with ultrabright flashing LEDs visible over a 270-degree angle.
Alarms are reset by pressing the operating button, which is oversized to allow easy use with thick gloves.
To ensure the monitor is regularly calibrated, a "calibration due" prewarning showing the number of days remaining appears on every startup within 30 days of the next calibration date.
Automatic zeroing on startup is also available as an option.
Designed for harsh conditions, Custodian CDL is ingress protected to IP66, has a shatterproof Triax casing and is supplied with an impact-resistant rubber boot.
Despite its ruggedness it weighs only 500g, making it easy to carry or wear for a complete shift.
The monitor and its removable battery pack, which is secured by a steel "click-lock", are both certified intrinsically safe, allowing the pack to be changed in hazardous areas if required.
Unlike nickel cadmium batteries, the nickel metal hydride pack can be trickle-charged and recharged at any point without damage.
A full charge powers the instrument for at least 12 hours. Request a free brochure from Crowcon Detection Instruments ...
