Alphasense Hydrogen Sulfide sensors operate using well-known fuel cell technology. The H2S-A series sensors are designed for continuous use between -30C and +50C, making H2S-A1 ideal for Oil and Gas/Petrochemical applications in adverse climatic conditions.
The H2S-A offers our leak free guarantee and good, reliable detection performance. The leakproof housing is moulded in colour coded plastic for ease of identification.
Our unique ATAV test and validation system enables us to perform customised testing to customer requirements. A record of each sensor's performance is stored in our database, accessible via the sensor barcode, available as hard copy evidence and as a powerful diagnostic tool.

Alphasense Hydrogen Sulfide Miniature sensors operate using well known fuel-cell technology. The Alphasense H2S-D series offers our unique leak-free guarantee and superior detection performance all in a diameter of 14.5mm. Only its size is reduced, not its performance or guaranteed life. The leakproof housing is colour coded for ease of identification.
As with all other Alphasense sensors, the use of stabilisation racks to continuously monitor every sensor during initial conditioning ensures that only sensors operating within specification are passed to the companies unique ATAV (Alphasense Test and Validation) system. This also enables us to perform customised testing to customer requirements. The key operating characteristics for every sensor are recorded against the sensor serial number, which is bar coded onto the sensor. This data can be released at the time of despatch so that full traceability is maintained.

SENSOR FEATURES:
- Sensor designed to reliably detect H2S at concentrations from 1-100 ppm.
- Rugged sensor undamaged by exposure to temperature and humidity extremes.
- Fast response and complete recovery after H2S exposure.
- Large, stable, easy to measure resistance change on exposure to H2S.
- Preliminary studies indicate sensor response is stable (does not go to sleep).

MILLENNIUM ELECTROCHEMICAL TOXIC GAS DETECTOR
Net Safety's toxic gas detector, the Millennium, delivers safety, security and performance - protection you can trust! Using the latest in electrochemical sensor technology, the Millennium continuously monitors your site for a wide range of toxic gas types. The Millennium is fast and accurate and requires only periodic calibration and maintenance.
Enclosed in a compact and explosion-proof housing, the Millennium features a power disconnect switch to simplify maintenance, a clearly visible scrolling LED display for calibration and configuration and meter jacks for easy current loop monitoring. The Millennium has both an internal push button and external magnetic switch for either intrusive or non-intrusive calibration and configuration.
The Millennium is designed for 12 or 24 VDC systems and is available with analog, relay and digital output configurations as well as a Low Power option- just let us know your requirements!
Net Safety has once again designed a simple yet precise toxic gas detector, engineered to the highest standards for performance and quality, and ideally suited to withstand the challenges imposed by high-risk industrial applications.
A full range of gases and custom configurations are available (ppm ranges etc.). Please consult our Sales Department.

The S4100T Intelligent Sensor is a highly reliable, self-contained, microprocessor-controlled hydrogen sulphide transmitter with integral 3 digit readout. It is designed to measure and display concentrations of H2S in the 0-20 ppm, 0-50 ppm or 0-100 ppm range, but will continue to display concentrations up to 120% FSD. The sensing element may be incorporated in the transmitter housing or remotely mounted at distances of 600 meters. The sensor employs thin film metal oxide semiconductor (TFMOS) technology as the measuring principle.
