Detector TC4-AQM

COVI detector (UK) Model: TC4-AQM Instrument: Product Features: With the continuous improvement and updating of the concentration of nitrogen oxides highway tunnel environmental testing will gradually become the main tunnel ventilation related design parameters, industry Specification forthcoming. This test is based on the original measure carbon monoxide and visibility on the reserved slot, and the output signal of nitrogen oxides analysis module and standard cylinders reserved slot, the device can be added through the hardware design of nitrogen oxide detection. The main technical indicators; measuring range: CO: 0 ~ 400ppm (measuring range adjustable) NOx: 0 ~ 50ppm (optional) VI: K = 0 ~ 35x10-3m-1 (measuring range is adjustable) Accuracy: CO : ± 1ppm VI: ± 0.1x10-3m-1 or 0.7 transmittance NOx: ± 0.1ppm supply voltage: 76 ~ 265VAC, 50Hz / 60Hz Ambient temperature: -50 ~ + 70oC communication interfaces: RS232, RS485, RS422 Protection class : IP68 (spray aluminum housing) CE-Compatibility: Complies with EMC Directive 89/336 / EEC, Low Voltage Directive 73/23 / EEC requirements for installation: tunnel car dealers direction, the right side of the tunnel wall, 3 to 4 meters high
