Simtronics is pleased to announce the put on the market of the GD1, a new generation of open path detector.
The GD1 innovates by creating a new standard of toxic gas detection. At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain, and fog. The laser scans single absorption lines where there is no interference from other gases. This new technology constitutes an important progress with exceptional performances and a extreme reduced maintenance.
Unlike traditional methods for detecting H2S (MOS or EC cell), the GD1 needs no recalibration and can replace multiple standard detectors to cover the same risk. Compared to traditional detectors the GD1 offers:
• Faster detection
• Reduced maintenance
• A life calibration
• Fast acting
The GD1 is also available with a dual output gas configuration, Methane and Hydrogen Sulphide.
Supplied with worldwide hazardous area approvals. Suitable for use in SIL 2 systems.
With its level of detection lower than 5ppm and it is faster response time (T90 < 5 sec) the GD1 is ideal to ensure the personnel safety on petrochemical installations onshore or offshore or for the sites of treatment of waster water.
Furthermore, the GD1 offers real cost savings, using a single transmitter / receiver pair, the detector covers distances of up to 100 metres. Installation and maintenance costs are reduced as fewer devices are needed to cover the same risk as several point detectors.
As with all Simtronics’ products, the GD1 is designed for early detection of hazardous events. It’s built to work safely in extreme areas and withstand the hardest environments onshore and offshore.

The Model S4000CH Intelligent Sensor is a microprocessor- based transmitter designed for use with General Monitors' catalytic bead sensors. The unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas. It is designed to monitor combustible gases and vapors within the lower explosive limit (LEL) and provide status indication and alarm outputs. Complies with ANSI/ISA 12.13.01-2000 performance requirements for combustible gas detectors.

The gas measuring systems for explosive gases and vapors made by J. Dittrich Elektronic determine the concentration of explosive gases and vapors in air in an ambient temperature from -10 to +50° C.
A pellistor or semiconductor sensor detects methane (CH4), hydrogen (H2), propane (C3H8), alcohol and benzine; additional hydrocarbons on request.
The calibration is carried out with the aid of the respective test gas by means of a potentiometer; however, a certain amount of cross-sensitivity of the sensor with regard to the other substances always remains.
Low-cost infrared measuring system for methane
Since the cross-sensitivity of the sensors gives rise to problems when monitoring methane, J. Dittrich Elektronic developed a new infrared measuring system which detects specifically methane quicker, more accurately and at less cost than conventional infrared systems.

The effectiveness of SIMTRONICS remote detectors (accuracy, fast response time and high reliability) guarantees the ultimate protection against the risks associated with gases in industrial environments.
The housings are given a special surface treatment to improve their resistance to corrosion (stainless steel or aluminium housings).
The measurement process is based on OXYCOL™ low temperature catalytic oxidation, enabling detection of all combustible gases and gives the detector an extremely long lifetime.
All the explosimeters are equipped with :
• An exclusive system of alarm verification in case of scale overrun,
• A linear response,
• A high stability,
• A very short response time.
The interchangeable and removable cartridges (as well as the support independent from the electronic box) make the remote detector easy to use and maintain.

Gas detection : O2, H2S, NH3, CO, NO, NO2, H2, SO2, Cl2, HCl, HCN…
The modern technologies used offer a high resistance to the humidity and temperature compensation as well as stability over time. In order to meet every requirement, SIMRAD Optronics ICARE proposes two different detection technologies :
• Electrochemical cells enabling a wide detection range and excellent selectivity.
• Semi-conductor cells providing extended detector lifetime.
The interchangeable and removable cartridge along with the wall mounting,
independent from the electronic housing, make this detector particularly simple to use.
• NH3 detection, low temperature
To meet needs of cold chains, a low temperature version enables detection down to -40°C.

The LumaSense Photoacoustic Field Gas-Monitor Innova - 1412 is a highly accurate, reliable and stable quantitative gas monitor. Its measurement principle is based on the photoacoustic infra-red detection method. This means that the 1412 can measure almost any gas that absorbs infra-red light.
Appropriate optical filters (up to 5 + water vapor) are installed in the 1412's filter carousel so that it can selectively measure the concentration of up to 5 component gases and water vapor in any air sample. Further, the instrument can compensate for interference between the measured gases, using the unique Cross-compensation feature. The 1412's detection limit is gas-dependent but typically in the 10-² ppm region.
