 Automatic monitoring for a long time measurement 
 ZX7M-ecom KD portable precision gas analyzer equipped with improve the pretreatment unit, such as: fine filter, peristaltic pump, gas cooler, suitable for long time continuous analysis and monitoring. Measurement instrument capable of independent fresh air switch and sensor auto-calibration, automatic recording measurement data. 

 Peltier gas cooler 
 Dry the sample gas to the analyzer, the accuracy of the measurement values ??and equipment service life in terms of is absolutely necessary, especially in the case of the low flue gas temperature and high humidity flue gas, such as long measurement, analysis The instrument is equipped with high-power gas cooler, ecom-KD is to meet this requirement, its high-power Peltier gas cooler, suitable for long hours, can effectively protect the sensor, the measurement of accurate data. 

 Heating diagnosis 
 Heating diagnosis suitable for special measurement conditions and the point of the old device to directly measure the heat losses, after the end of the measurement for diagnosis (eg, within 24 hours) and to map out diagnostic data, and suggests that defects in the boiler combustion or combustion state and needs to be improved. 

 User password key 
 The instrument to normal operation in the case of electronic key can not operate the instrument without authorization, the key to pull out all the features of all of atresia, each instrument can authorize multiple users.
