Description Vendor

The Exmonitor / Gasmonitor is a gas measuring and alarm system designed for detecting toxic gases and oxygen levels. It features electro-chemical measuring cells, a dual conductor design, and is suitable for both hazardous and non-hazardous environments. The system provides real-time monitoring, warning signals, and can initiate protective measures such as ventilator activation or alarms. It is ATEX-conformity for applications in hazardous areas (zone 1 and 2) and offers dual electrode sensors for accurate measurements. The Exmonitor is specifically designed for potentially explosive atmospheres with a continuous display of gas concentrations, while the Gasmonitor is for non-hazardous areas. The system includes a sensor, analysis unit, and controllable units such as ventilators, warning lights, and solenoids. It supports one-man calibration, easy sensor change, and offers a range of technical specifications for various gases, including CO, H2S, SO2, NO, NO2, Cl2, HCN, HCl, H2, O2, and NH3.

Use Cases

  • Monitoring and warning signal for excessive concentrations of toxic gases
  • Monitoring and warning signal for lack of oxygen
  • Initiating protection measures such as ventilator activation or cut-out functions
  • Providing optical and acoustic alarms for organizational protection

Capabilities

  • Detection of toxic gases and oxygen
  • Measuring and displaying current concentration of gases
  • Initiating technical and organizational protection measures
  • Providing optical and acoustic alarms
  • Supporting one-man calibration
  • Easy change of sensor
  • Dual electrode design for oxygen measurements
  • Three-electrode design for toxic gas measurements
Bieler + Lang GmbH Bieler + Lang GmbH is a German gas detection systems manufacturer, based in Achern, with over 50 years of experience specifically in hydrogen leak detection technology. The company's ExDetector HC 100 and HC 150 sensors use catalytic combustion (pellistor) technology to detect hydrogen leaks as a percentage of the lower explosion limit (%LEL), since hydrogen's odorless, colorless nature and inability to be detected by infrared sensors make specialized detection essential; its addressable and aspirating detectors serve safe areas, ATEX/IECEx explosive zones, and hard-to-access spaces like clean rooms. Bieler + Lang's ExDetector X5 combines up to two sensor heads with contactless one-man calibration and supports detection of over 400 gases, while the GMC 8034 evaluation unit serves as a compact control center for gas detection systems. All devices are developed, manufactured, and calibrated in-house under strict quality standards for industrial, research, and energy technology applications.
