Oxygen Deficiency MonitorsA wide range of monitors designed for ease of installation and continuous monitoring even in the event of a mains failure. We offer a number of different repeater panels covering every scenario from single monitor to 64 channel requirements. Wessington can offer a full design and installation service for every type of system. The system is modular in design to allow easy build up of different modules to suit every requirement. Systems can also be expanded on site retrospectively if requirements should change. Oxygen deficiency monitors should not be used for the detection of carbon dioxide gas.Personal MonitorsGasPod A personal, compact and extremely robust personal oxygen monitor, with two year long life sensor and large clear LCD display, for continuous monitoring of oxygen concentrations in surrounding air. The GasPod offers dual protection for the user from the potential hazard of oxygen deficiency in the presence of nitrogen, argon and helium together with monitoring of oxygen enrichment. Applications T he GasPod personal oxygen monitor provides four alarm settings for both oxygen defi ciency and enrichment monitoring. The monitor continuously checks the concentration of oxygen in the surrounding air and provides both visual and audible alarms should the detected concentration of oxygen fall below the pre-set low alarms or above the pre-set high alarm levels. The monitor contains a long life two year oxygen sensor and battery pack that provide a continuous two year operation.NB Oxygen deficiency monitors must not be used for the detection of carbon dioxide gas. Key features > Confidence heartbeat & service indication on LCD display with large clear indication for maximum user visibility > Simple automated push button calibration in fresh air > Different audible, visual and vibration indications for two primary warning alarms and two critical alarm settings > Rugged highly visible enclosure and durable clip to allow user to attach the GasPod securely to garments > Loud audible alarm for maximum volume > No requirement for charging. Two year sensor/battery pack which cannot be switched off protecting the user at all times > Live readings with no sample interval for rapid alarm response times > Oxygen concentration reading suppressed in alarm condition to avoid user interpretation of safe levels (continuous reading available upon request) Equipment/Service Options Certified test gases for precise checking of alarm levels Annual calibration service with certified test gases and documentation Monitor exchange service available to ensure continuity of user protection with no loss of cover during service times Technical Specification Details Dimensions H80 x W45 x D33 mm Weight 200gm approx Alarm Indications LCD Audible Alarm 82 dBA at 10cm Vibrate at 18% Read-out LCD display to 0.01 Calibration test By push button adjustment in fresh air Alarms High Alarm (22.5%)* Critical High Alarm (24%)* Low Alarm (19%)* Critical Low Alarm (18%)* * Alarm levels are factory pre-set and may be varied according to industry best practice levels. Accessories
Service and Support Design and installation We can advise on how to integrate your existing equipment and/or design systems to suit specific requirements and maximise safety and reliability. Calibration It is recommended that all products are calibrated at least every 12 months, either on site or in the factory. Maintenance and refurbishment A maintenance check is advised every 12 months. We can offer a choice of maintenance contracts and will refurbish/upgrade any product, regardless of age or condition.

QFM-330
SIMPLE BATTERY POWERED MODULAR SYSTEM FOR CONTINUOUS MONITORING OF OXYGEN CONCENTRATIONS WITH NO NECESSITY FOR MAINS CONNECTION
DESCRIPTION
The Q-330 Oxygen Monitor and Alarm System combines
simple, reliable operation with ease of installation, providing a low cost
solution for oxygen monitoring. It continuously monitors the concentration of
the oxygen in the air surrounding its sensor and provides both visual and
audible alarms when the monitored concentration falls below pre-set levels. The Q-330 system is designed to be completely modular
with the basic building being the QFM-330 monitor. This unit incorporates a
sensor which is placed at an appropriate sensing point by simply screwing to
the wall (NO ADDITIONAL POWER SUPPLY IS NEEDED). The QFM-330 also includes
audible and visual alarms and by simply plugging in additional modules to the
base unit, a number of additional facilities are available. The alarm can be
repeated at a remote site; a digital display of the oxygen concentration can
be added and a switching unit for connection of fans, valves or other alarm
systems can be provided simply by selecting the appropriate additional
modules. A computer connection can also be included. The repeater units are
all battery powered, with the exception of a further mains powered module
which incorporates a boosted klaxon and warning beacon, for use in
particularly noisy operating environments. Additional modules can be added to
the system when initially installed, or at a later date without need for
modification of the basic unit. Any number of base sensing units can be fitted at any
site to allow for the need for multiple sensing. The Q-330 by selective use of
appropriate modules can provide a low cost solution to every scenario from a
simple single monitor to a large monitoring system spread over a number of
rooms requiring many monitors and alarms.
OPERATION
Two independent alarm levels are pre-set on the base
unit. These provide a ‘Low Alarm’ at 19% and a ‘Critically Low’ alarm
should levels fall still further to 18%. Audible alarms are 85dBa at 30cm for
all battery operated units. Long life oxygen sensors are employed which will
provide twelve months operation in normal use. A replacement sensor pack can be
supplied by post without the need to return the unit each year and additional
modules can be added, if required, without any modifications to the existing
system.
