Details & Features
B-DETECTION PLUS m is a portable case-based solution for measuring CO, CO₂, O₂, and optionally absolute humidity and residual oil (VOC¹) in accordance with DIN EN 12021. Air quality can be tested directly at the cylinder, at the compressor, or at the intake using an optional ambient air pump. The control unit allows the selection of suitable measurement profiles. In the event of limit value exceedance, a visual warning is issued. An integrated data logger with SD card functionality enables the evaluation of defined individual measurements. The transport case is dust- and water-resistant according to IP65.
¹ Humidity and residual oil measurement (VOC) are optional. Residual oil is measured based on volatile hydrocarbons (VOCs). Sensor calibration is based on isobutene.
- NO WAIT TIME I: Thanks to its patented special design, the response time of the dew point sensor has been drastically reduced – enabling virtually instantaneous humidity measurement.
- NO WAIT TIME II: The rapid-venting feature allows for fast disconnection of the gas sampling unit from the air extraction point.
- TOP SERVICE ABILITY: Fast and easy access to the sensors ensures outstanding maintenance convenience.
- PURE AIR: Approved as a measuring instrument for PureAir Silver certification.
