G1010 Mark II Series Oxygen analyzers

 

Applications
 

Air separation plants
Nitrogen purged soldering systems
Cylinder gas quality
Food packaging and storing
Purge gas monitoring
Landfill gas monitoring
Glove boxes
Workplace air monitoring
Medical monitoring

 

The oxygen analyzers in the G1010 Series use galvanic cell primary elements and can measure oxygen concentrations from 100% to 0.1ppm (parts per million) in a variety of gases. The instruments are micro-processor-controlled and provide exceptional performance and versatility.

A large multi-digit, auto-ranging LCD shows the concentration and user-adjustable parameters.

Two alarm channels, user-programmable to be high, low or off, each provide one set of volt-free changeover contacts, and can be set to any concentration within the span of the instrument.

A user programmable analogue output can be set to one of several ranges. A choice of 0 to 5v or 4 to 20mA is provided at the time of ordering.

Several versions of sensor are available, enabling the analyzer to operate at optimum performance in a diverse range of applications. These include a sensor suitable for operating in the presence of high concentrations of mildly acidic gases such as carbon dioxide and hydrogen sulphide.

Remote sensor versions are available that allow the separation of the control/ display module and sensor by up to several hundred metres. Depending on the distance and concentration being measured, the sensor is either connected directly to the display module or via an integral two-wire transmitter.

Because the sensor conforms to the ‘simple apparatus’ category as defined by European standard EN 50020, remote sensors may be located in a hazardous area. A suitable zener barrier or galvanic isolator must be inserted between the sensor assembly and the control/display module.

Three other analyzers are derived from the G1010:  The bench-top G210 is a mains powered analyzer which can be equipped with a variety of sampling systems and accessories including a pump, filter and flow control.

The wall-mounting G610 is packaged in an IP65 enclosure allowing it to be located in almost any industrial situation.

The fully portable G810 is fitted with a sample pump as standard and can operate for over 12 hours on its rechargeable battery pack. Specification sheet HPS130 gives full details
