Hazardous Gas Analysers – ACCURRA-Hz

Our ACCURRA-Hz is a Hazardous Area Certified Analyser suitable for the toughest applications such as- Chemical Processes, Combustion Process, Pharmaceuticals, Petrochemical & Refinery Processes and Blanketing etc. the list is endless.

The Analyser ACCURRA-Hz gives excellent Linearity, Accuracy and Repeatability. The sample handling system for this analyser is specifically designed as per your process requirement to maximise performance.

Some of the most widely used measurements are:
Oxygen 0-100 ppm, 0-25 %, 0-100 %
Carbon Di-Oxide 0 5000 ppm, 0-100 %
Methane 0-100 %
Hydrogen Sulphide 0-100 ppm
Carbon Monoxide 0-1000 ppm, 0-100%
Hydrogen 0-1000 ppm

We can give few measurements in transmitter – INFINITY-Tx such as percentage Oxygen, Trace Hydrogen Sulphide etc.

The Transmitter– INFINITY-Tx is the simplest but the most powerful of Gas Analysis device and its installation and commissioning totally hassle free. It works on two wires and has a local display. It is certified for Hazardous area use and rated as IP66. It can be directly mounted on pipe line.

The re-transmission 4-20 mA output can be remotely connected to your DCS or data logger.
