Product Description:
Ontech820 can selectively sample VOCs in the atmosphere according to specified sequences or remotely control the VOC sampling system (atmosphere) based on user needs. When law enforcement officers receive complaints from residents or when VOC concentrations exceed the standard, they will immediately remotely trigger the installed sampler for sampling through a mobile app or computer monitoring interface.
Execution standards:
HJ732-2014 "Sampling Gas Bag Method for Volatile Organic Compounds in Fixed Pollution Source Exhaust Gas"
JJF 1172-2007 "Calibration Specification for Volatile Organic Compound Photoionization Detector"
System composition scheme:
Power supply unit, sampling tank, mass flow meter, high-precision pressure sensor, multi position switching valve, communication control unit (including SIM card), drive unit, sampling unit, operation unit, main cabinet, mobile app and upper computer software, etc.
Product features:
1. Using wireless remote (4G module) control, it can be remotely controlled through computers, mobile phones, etc; The control methods are divided into manual control and automatic timing control; Manual control can immediately trigger the system for sampling, while automatic control can start the system at regular intervals for sampling, or trigger sampling through signals generated by installed PID sensors
2. Adopting a dual-purpose AC/DC power supply, when the site does not have 220V power supply conditions, a solar cell+battery power supply method can be optionally selected
3. The control solenoid valve has the characteristics of good sealing and strong corrosion resistance
4. Support 2-16 sampling channels, customizable; It can be sampled simultaneously or in different time periods
5. Optional Suma tank, customizable vacuum box+PTFE airbag
6. Optional PID detector, supporting trigger sampling
7. Explosion proof locations are required, and explosion-proof sampling cabinets need to be selected
8. Touch screen display and operation interface
