Gaopin Technology NGP40-VOC portable VOC Gas Detector is used to quickly detect TVOC gas concentration and ambient temperature and humidity measurement, and the measurement exceeds the limit value to send out sound and light vibration alarm. NGP40 uses 2.31 inch high-definition color screen for real-time display, adopts a gas sensor of a good brand in the industry, and uses the principle of thermal conductivity detection. Professional circuit design, mature kernel algorithm processing, unique shape design, and a number of patents for software works and appearance have been obtained. NGP40 series Gas Detector is suitable for detecting the concentration of gas in pipelines or confined spaces and atmospheric environments, gas leakage or high concentration single gas purity of various background gases such as nitrogen or oxygen. More than 500 types of gases are detected.

● Detect VOC gas concentration.
● Built-in pump-suction measurement, integrated water vapor and dust filters, to prevent damage to sensors and instruments due to water vapor and dust, can be used in high humidity, high dust environment rapid response, special gas path design, sampling distance is greater than 10 meters, can directly detect negative pressure or positive pressure -0.5~2 kg of gas.
● Rich man-machine interface
The 2.31-inch high-definition color screen displays real-time concentration, alarm, time, temperature, humidity, storage and other information, and the menu interface uses high-definition simulation graphics to display the function names of each menu.
● Large-capacity data storage function (capacity can be customized), support a variety of storage methods, optional RS485 communication.
Standard 100,000 pieces of data storage capacity, support real-time storage, timed storage, or only alarm concentration data, support local viewing, deletion of data, and upload to the computer through the USB interface for data analysis or printing.
● High Temperature Gas Detection (Optional)
Optional high-temperature sampling, cooling, filtering handle or high-temperature and high-humidity pretreatment system can detect flue gas at a temperature of 400 degrees. Higher temperature gas detection can be customized.
● Three display modes can be switched
The concentration of four gases is displayed at the same time, and the concentration of single-channel gases is displayed in a large font cycle, and the real-time curve is displayed.
● Graphical display, reflecting the trend of gas concentration change over a period of time in the form of curves.
● Data recovery function, in case of misoperation, you can choose to partially or fully recover.
● You can set whether to display the maximum, minimum, and average value.
● Standard USB charging interface, with charging protection function, support USB can work normally.
● 4500mA large-capacity rechargeable polymer battery, which can work continuously for a long time.
● High-precision temperature and humidity measurement (optional).
●Support real-time detection or timing detection, and the pump can be turned off when not detected to prolong the start-up time.
● A variety of alarm methods, multi-directional three-dimensional indication of alarm status when alarming.
Including sound and light alarm, vibration alarm, display visual alarm.
The types of alarms include: concentration alarm, underVoltage alarm, and fault alarm.
● Multiple alarm mode settings: low alarm, high alarm, interval alarm, weighted average alarm.
● Misoperation identification function: Misoperation of concentration calibration is automatically identified and prevented, which can avoid defects caused by human factors.
● Zero point automatic tracking, long-term use is not affected by zero point drift.
● Multi-level calibration of the target point to ensure the linearity and accuracy of the measurement.
● Chinese and English interface can be selected.
●Wide operating temperature: -40~+70°C, support temperature compensation.
● Log recording: record calibration logs, maintenance logs, fault solving countermeasures, sensor life expiration reminders, and next concentration calibration time reminder functions.
●Meet the design requirements of intrinsically safe circuits, anti-static, anti-electromagnetic interference.
●IP65 protection level, waterproof, dustproof, explosion-proof, shockproof.
