Gas Detection 7 Toxic Gas Detector for Small Hydrogen Leak Detection
The TS4000H Gas Detector from General Monitors (USA) continuously monitors for hydrogen. It features a precision electrochemical hydrogen sensor that has a T90 response of under 30 seconds and minimal zero shift across its operating environmental conditions. Furthermore, it is unaffected by short-term (≤ 2.5 min) exposure to hydrogen concentrations up to 50% LEL. The TS4000H Detector features a sophisticated design with many advanced functions, including 4-20 mA output, 8 amp relays, HART or Modbuscommunications, and a 3-digit LED display that displays gas concentrations in ppm. The system also displays fault codes for troubleshooting and provides complete status to the ControlRoom.
All of the electronics are contained within an explosion-proof housing so that gas sensor information can be processed at the sensor site. The gas sensor may be remote mounted up to 2000 feet (610 meters) away from the electronics.
The interface module’s galvanically-isolated, intrinsically-safe design also supports sensor field replacement without special tools or hot work permits. The TS4000H detector is easy to install and calibrates by activating a magneticswitch and applying gas.
Process engineers who need to protect people, equipment, and the environment will find the TS4000H hydrogen sensor well suited for a broad range of industries where hydrogen gas leaks are a hazard. For worldwide application, the detector complies with ATEX, CSA, CE, GOST, and is certified for use in SIL 2 environments. In addition to monitoring for low hydrogen levels, the TS4000H can be configured to detect a variety of other toxic gases including; ammonia, carbon monoxide, chlorine and sulphur dioxide.

CL:AIRE Research Bulletin Validates Benefits of
Continuous Ground- Gas Monitoring
The benefits of continuous ground-gas monitoring have been given significant recognition within the contaminated land industry due to the publication of a recent technical bulletin compiled by CL:AIRE (Contaminated Land: Applications in Real Environments.)
The paper entitled “The Utility of Continuous Monitoring in Detection and Prediction of “Worst Case” Ground-Gas Concentration” demonstrates how collecting continuous data can improve current site investigation methods. It also reveals how more sophisticated methods, without the need for additional resource efforts can be adopted, and introduces new analytical tools which allows for more appropriate risk assessment.
The Ion Science (UK) GasClam is the only ground-gas monitor on the market to continuously
measure VOC’s, CH4, CO2, O2, H2S, CO, atmospheric & borehole pressures, temperature and water level which perfectly meets the requirements discussed within the CL:AIRE Research Bulletin.
Topics of the CL:AIRE Research Bulletin includes "Detecting and predicting ’worst-case’ conditions and "Processes controlling gas production and migration"
CL:AIRE is an independent not-for-profit organisation established to stimulate the regeneration of contaminated land in the UK by raising awareness of, and confidence in, practical sustainable remediation technologies.
