Analytical Technology Launches AutoTest D12 Gas Monitor for Accurate Toxic and Combustible Gas Detection in Water Industry

Posted: Wednesday 17th December 2008

Specialist electrochemical sensor manufacturer Analytical Technology announces the availability of its D12 2-wire loop powered Toxic/Combustible Gas Detector, a unique sensor which can provide the water and wastewater treatment industry with accurate and reliable readings of over 30 gas concentrations.

The monitor is unique because every day the sensor is verified with a gas sample produced on demand. This AutoTest feature removes the need for manual checking and gives the D12 the lowest cost of ownership of any gas detector.

Water and wastewater treatment processes regularly require the use of toxic gases and chemicals which need constant monitoring and detection to ensure safety in the plant environment. The D12 Toxic / Combustible Gas Detector can efficiently monitor gas quantities within the installation area using smart electrochemical gas diffusion sensors. The innovative device is easily installed, operated and maintained, with clear menu-driven set up pages and a large LCD numerical display so gas values can be easily read along with alarm indication.

The D12 utilises Analytical Technology’s Smart sensors. All calibration and AutoTest data is held within the memory of the sensor. If a new sensor is needed it arrives ready calibrated and all that is needed is to plug it in: the D12 does the rest.

The Auto Test self-checking sensor system generates a small sample of gas every 24 hours to verify operation, ensuring accurate response checks. The detector uses an electrochemical sensor for toxic gases and a catalytic bead for combustible gases, which offer accuracy levels of ±10% of value. The monitor can be used in hazardous conditions, including outdoors and in high winds, while still giving reliable data.

Operation of the monitor is non-intrusive and calibration, alarm, set up options and data view are all accessible via a magnetic tool and can also be done remotely using a bench transmitter. The generators store run time information, such as sensor condition, gas type, range and calibration data using an internal logger, which can be accessed at anytime on the display. Data can be downloaded using the MOBUS™ protocol and is also compatible with HART™ communication output.
