Hitech Instruments GIR 5000 3 Gas Landfill Monitoring System (Wall Mount)

Landfill gas and Bio gas is produced by the bio-degradation of waste. Landfill gas is produced from general waste buried in the ground; and bio-gas from plant and animal waste products contained in a sealed digester tank.

Both gases comprise mainly methane (CH4) and carbon dioxide (CO2). The methane component is either burnt as a fuel or flared off as waste.

Our landfill gas / Bio gas analysers maximise the extraction of energy and ensure it is safe to burn without explosion - (the explosion problem occurs if air, i.e. oxygen, infiltrates the gas).

• Measures oxygen, methane and carbon dioxide
• Alarms for all measurements and sample flow
• 4 to 20mA outputs for all measurements
• Optional safety alarm and shut-down system

 

The GIR5000 is a gas analyser unit for measuring the concentrations of oxygen and methane in landfill gas and biogas. As an option, the concentration of carbon dioxide can also be monitored.

 

 

Hitech Instruments K1550  Thermal Conductivity Gas Analyser (Panel Mount)

Hitech's Ammonia analyser and toxic analyser range uses either thermal conductivity (K range) electrochemical (T range) or flammable gas sensor (F range) to produce highly accurate results. The sensors used by this gas analyser range are extremely stable, as well as being highly reliable and accurate. The sensor technology chosen is determined by the application. They are available in a range of packages to suit all requirements from robust portables to fixed installations.

•           Gases measured include hydrogen, carbon dioxide and argon
•           Hazardous area sensor option
•           4 to 20mA isolated output
•           Two user-configurable alarms
•           Programmable alarms and analogue output
•           Maintenance free sensor

 

Hitech Instruments G1010 Galvanic Oxygen Analyzer (Panel Mount)

• Exceptional dynamic range
• Single point calibration
• Microprocessor-controlled
• Programmable alarms and analogue output
• Hazardous-area models available

The G1010 oxygen analyzer uses a galvanic oxygen cell to measure oxygen over an exceptional dynamic range of 100% to 0.1ppm (parts per million) in a variety of gases. The instruments are microprocessor- 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 of 0 to 5v or 4 to 20mA is available 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.
