This portable measuring device combines three fundamental functions in one device:
- Portable measuring device for the personal, continuous monitoring of the methane concentration with audiovisual signaling.
- Portable measuring device for the punctual measurement of the methane concentration by
means of diffusion. The gas sampling can be made also with the built-in gas pump by means of a test adapter with tube and testing probe. - Portable measuring device for the measurement of the methane concentration in gas exhaust pipes. The gas sampling occurs with the built-in gas pump by means of a test adapter with tube and testing probe.
- Measuring range: 0.00...5.00...100.0 % CH4 for the personal and punctual measurement
- Measuring range: 0.0...100.0 % CH4 for the measurement in gas exhaust pipes
- Principle of measurement: Catalytic combustion and thermal conductivity with gas diffusion entry
- Protection of the catalytic combustion sensor against high gas concentrations
- Increased accuracy by patented compensation with built-in humidity and temperature sensor
- Built-in pressure compensation for the measurement in gas exhaust pipes
- Built-in gas pump with flow control
- Test adapter with tube and testing probe for the gas sampling by means of the built-in gas pump
- Zero point and sensitivity control with test gases
- Illuminable graphic LC-display with 4-digit, 10 mm high, measured value display and a second line for a quasi-analog bar graph or text display
- Measured value display is switchable on % LEL
- Limit values and status informations in plain text notation
- Code lock against unauthorized operation
- Adjustment of zero point and sensitivity as well as settings and status requests over pushbuttons
- Error self diagnosis with alphanumeric display
- Two independently adjustable limit values for audiovisual signaling in the 0… 5% CH4 range and two additional adjustable limit values in the 0… 100% CH4 range. Monitoring of the limit values can be switched off.
- Alarm signaling: indication on the LC-display, two flashing LED´s and an acoustic signal generator
- Carbon fiber reinforced, antistatic plastic housing
