Portable Gas Detector for Carbonic Oxide and Carbon Dioxide

Introduction:
Portable combo gas detection alarm for portable rapid detection of a variety of gas concentrations, temperature and humidity measurement and excessive alarm occasions. PSD602 composite combo gas detector with 2.31-inch high-definition color display real-time display of concentration, selection of well-known brand of gas sensors, the main detection principles are: electrochemical, infrared, catalytic combustion, thermal conductivity, PID photo ion. Advanced circuit design, mature kernel algorithm processing, has made a number of software patents and appearance patents. PSD602 can detect the pipeline or confined space, the atmospheric concentration of gas, can detect gas leaks or a variety of background gas is a high concentration of nitrogen or oxygen, a single gas purity, gas detection of more than 500 species.

  Data can also be uploaded to the computer through the USB interface, using PC software to analyze data and store and print.
USB charging interface, available computer or rechargeable treasure, compatible mobile phone charger, over charge, over discharge, over voltage,
  Short circuit, overheat protection, 5-level precision power display, support for USB hot swap, the detector can work normally when charging, optional RS485 communication
4500mA high-capacity rechargeable polymer battery can be a long time continuous work
Sound and light alarm, vibration alarm, visual alarm, under-voltage alarm, fault alarm, alarm multi-directional three-dimensional display alarm status.
alarm value can be set, the alarm mode optional low alarm, high alarm, interval alarm, weighted average alarm
High-precision temperature and humidity measurement (optional), while the temperature sensor compensation, the instrument temperature range of -40 to 70 degrees,
  Can detect 400 degrees gas, higher temperature gas detection can be customized (optional high-temperature sampling cooling filter handle or high temperature and high humidity pretreatment system)
Up to 1 to 4 gases can be detected at the same time, the unit can be freely switched, the conventional gas does not need to enter the molecular weight, and the special gas needs to input the molecular weight
  Automatic calculation and switching, unit optional: PPM, mg / m3, Vol%, LEL%, PPHM, ppb, mg / L
Three kinds of display mode can be switched: Simultaneous display of four gas concentrations, large font cycle shows the concentration of single-channel gas, real-time curve, each channel
  Automatic cycle or manual cycle can be switched between, you can set whether to display the maximum, minimum, gas name, you can view the history curve.
Chinese and English interface options, the default Chinese interface, concise Chinese or English operation tips
data recovery function, you can selectively restore or restore all, eliminating the worries caused by misuse
zero automatic tracking, long-term use from drift drift.
Target point three calibration, to ensure the measurement of linearity and accuracy, both at the same time meet the national standards and local Bureau of Metrology standards.
concentration calibration misuse automatically identify and prevent, to avoid human factors caused by the poor.
Real-time detection or timing detection (for a relatively small amount of gas to be measured), the pump can be turned off to increase the boot time without detection.
can record calibration log, maintenance log, troubleshooting measures, sensor life expiration reminder, the next concentration calibration time reminder function
