One-touch monitor, four-gas protection
Multi-channel personal gas monitor combines sophisticated data management features with the simplicity of operation normally found in basic one-gas instruments
A new multi-channel personal gas monitor from Crowcon combines sophisticated data management features with the simplicity of operation normally found in basic one-gas instruments Although controlled by only one button, Custodian CDL features datalogging, data transfer to a PC and automatic calibration reminders, while offering a wide choice of sensors to provide simultaneous protection from up to four gas hazards

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, back-lit 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 one metre) is triggered along with ultra-bright flashing LEDs visible over a 270deg 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' pre-warning showing the number of days remaining appears on every start-up within 30 days of the next calibration date.
Automatic zeroing on start-up 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 ...
