Its electrochemical sensor uses diffusion sampling, while a rear clip and protective cover help keep the instrument accessible between readings. Select the NO2 measurement span that fits the concentration range required for your procedure.\u003c\/p\u003e\u003ch3\u003eRange and Sampling Choices\u003c\/h3\u003e\u003cp\u003eThe available configurations cover 0-20, 0-50 and 0-100 ppm. Each is a separate range option for the same instrument model. In its standard diffusion setup, ambient air reaches the sensor opening directly.\u003c\/p\u003e\u003ch3\u003eReadings and Alarms\u003c\/h3\u003e\u003cp\u003eA 128 x 64 monochrome LCD shows the gas reading and supports ppm and mg\/m³ display units. Backlight timing is adjustable, with automatic illumination during an alarm. Sound, light and vibration alerts draw attention to an alarm condition, and the sound alarm is rated at 85 dB. Set points can be configured for the monitoring procedure. The instrument retains 100 alarm records that can be reviewed on its display, and zero and self-calibration functions are available for routine setup.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eMH-1200H-S-NO2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMeasured gas\u003c\/th\u003e\n\u003ctd\u003eNitrogen dioxide (NO2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensor principle\u003c\/th\u003e\n\u003ctd\u003eElectrochemical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSampling method\u003c\/th\u003e\n\u003ctd\u003eDiffusion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRange options\u003c\/th\u003e\n\u003ctd\u003e0-20, 0-50 and 0-100 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplay\u003c\/th\u003e\n\u003ctd\u003e128 x 64 monochrome LCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDisplay units\u003c\/th\u003e\n\u003ctd\u003eppm and mg\/m³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAlarm modes\u003c\/th\u003e\n\u003ctd\u003eSound, light and vibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAudible alarm\u003c\/th\u003e\n\u003ctd\u003e85 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAlarm history\u003c\/th\u003e\n\u003ctd\u003e100 records viewable on the instrument\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBacklight\u003c\/th\u003e\n\u003ctd\u003eAdjustable timing and automatic alarm activation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery\u003c\/th\u003e\n\u003ctd\u003e2300 mAh rechargeable lithium-polymer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating temperature\u003c\/th\u003e\n\u003ctd\u003e-20 to 50 Degree C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIngress protection\u003c\/th\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e131 x 83 x 35 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApproximate unit weight\u003c\/th\u003e\n\u003ctd\u003e240 g with protective cover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eConfiguration Notes\u003c\/h3\u003e\u003cp\u003eThis configuration measures NO2 specifically; an NO detector or combined NOx detector serves a different measurement request. Choose range and alarm settings according to the intended monitoring procedure, and use the supplied instructions for calibration and checking. For diffusion measurement, leave the sensor inlet exposed to the air being monitored.
