Flow Sample System GDS 305

We also supply the GDS 305 sequential gas sampling system. This model has 1-48 sample points and can monitor up to four gases. The GDS 305 operates by sequentially extracting gas samples for a timed period by a central control unit via fixed sample lines. Gas levels readouts are provided by the central unit for monitoring purposes. The central unit has two alarm trip points per line and provides a range of signal outputs for annunciator and control functions. Please visit our website for detailed product specifications.

Labels can be created by customers and sent to our design team who will amend and process labels.

Please visit our website for details of artwork costings.

Test Equipment

Our Sensor Check Gas Kit features a calibration kit - regulator with a fixed flow 1 litre/minute), tube (3M length), test gas applicator cap and test gas bung plus carry case. The gas list includes flammable gases (test gas cylinder methane, propane, butane, pentane, acetylene, hydrogen), refrigerant gases (test gas cylinder R22, R134a, R152a), and toxic gases (carbon monoxide, carbon dioxide, hydrogen sulphide, sulpher dioxide, ammonia, nitric oxide, nitrogen dioxide, ethylene oxide, hydrogen chloride, chlorine), and test gas cylinder nitrogen and oxygen in N2.

Status I Indicator Panel

This model provides a wide range of warning and alarm applications with a combined audible and ‘text selectable’ illuminated window indication. The audible alarm can be silences at any time while the visual alarm continues to flash until the alarm condition has been cleared. The Status I Indicator Panel features safe, caution, gas and fault indicators. It has a maximum power per signal input 1 watt, protection IP65, a mutable 98 db at 30cm sounder, permanent sounder mute-option, remote mute terminals and more.

Status II Indicator Panel

The Status II Indicator Panel is a remote alarm unit that hosts a range of warning and alarm applications for effective use. The audible sounder is at 98 db at 30cm and can be muted at any time. If the sounder isn't muted it automatically mutes itself by default after a five minute period of continuous operation and the visual alarm window will stay illuminated until the alarm has been cleared. The Status II Indicator Panel is easy to install and is protected to IP65 standards.

Field Service

We provide a contract maintenance and repair service to ensure that you get the very best from your products. All products, no matter how high the quality, will need servicing or repairs at some stage and for equipment such as ours it is important that systems are maintained regularly to enable safe, effective use.
