BE-140 AD - Five-Gas Bench

Simultaneously measures CO, unburned HC ( as n-hexane) , and CO2 in automotive exhaust, using NDIR technology. Highly reliable with a long service life, BE-140 AD is certified for the three-gas portion of BAR-97 when incorporated into an exhaust-gas analysis system with sampling and control functions. Consists of solid-state infrared detectors, a microprocessor, and miniature mechanical components in a compact package. An optional galvanic cell measures O2. The unit can be wired for NO measurements, using either BE-220 or a electrochemical sensor. The microprocessor provides fully calibrated gas concentration values with compensation for atmospheric-pressure changes. Concentrations are output via RS-232C. In addition, it: adjusts gain control for the detector signals. performs automatic zero and electrical calibration without standard gases or mechanical checkers. reads span-gas data, computes a correction factor for each gas, and stores the factors in EEPROM. informs the user of alarms and self-checks. Field-proven, accurate, and very reliable, BE-140 AD is the heart of HORIBA' s MEXA-324 J/ 554 J series portable analyzers as well as many third-party analyzers. Applications For OEM integration into: Inspection-maintenance analyzers and systems Repair-grade analyzers BE-140 AD is certified for BAR-97 applications and conforms to the following standards and specifications: OMIL ( R99) Class 0 ISO/ FDIS 3930: 2000( E) DRIR ( France) TNO ( Netherlands) TUV/ PTB ( Germany)
