1、 Core technology: Ensuring data accuracy from the source

1. Deep preprocessing system: cracking complex working condition interference

The system is equipped with a deep condensation dehumidification+multi-stage filtration system, ensuring the cleanliness of the tested gas through two-stage protection:

Condensation dehumidification module: using low-temperature condensation technology to quickly remove moisture from flue gas, avoiding interference from water vapor on sensor detection, and preventing blockage caused by the accumulation of condensed water in pipelines, thus extending the service life of the equipment.

Multi level filtration structure: The primary filtration intercepts large particles (such as dust and fibers), and the high-efficiency filtration (HEPA) further removes particles larger than 0.3 μ m, ensuring that the purity of the gas entering the sensor reaches over 99.9%, significantly improving detection accuracy.

2. High precision detection unit: imported technology empowers core performance

Photoionization (PID) sensor: Imported high-performance PID sensor is selected, with a response time of ≤ 3 seconds and a detection limit as low as 0.01ppm. It can accurately identify hundreds of VOCs components such as benzene and alkanes, meeting strict requirements such as the Comprehensive Emission Standard for Air Pollutants (GB 16297-1996).

Constant temperature detection environment: The sensor is equipped with a built-in constant temperature module, which stabilizes the working temperature at 40 ℃± 1 ℃ through intelligent temperature control, eliminating the interference of environmental temperature fluctuations on the detection results, and expanding the device's applicability to extreme working conditions of -40 ℃~50 ℃.

3. Intelligent transmission and control: breaking down data silos

Dual mode transmission technology: Supports 4G wireless transmission and RS485/RS232 wired transmission, with real-time data uploaded to the environmental monitoring platform or enterprise mobile app, enabling remote monitoring, parameter setting, and fault diagnosis to avoid the risk of operators being exposed to toxic gases.

Automated calibration function: The system has automatic zero calibration and manual cross calibration capabilities, and can complete sensor calibration through remote commands, solving the problem of data drift caused by long-term operation. The maintenance cycle is shortened by 60%, and the annual maintenance cost is reduced by 40%.

2、 Performance highlights: Detail design highlights professional strength

1. Humanized interactive interface

7-inch high-definition touch screen integrates four core functions:

Real time data curve: dynamically display the trend of TVOC concentration changes;

Historical data traceability: supports querying historical records by time and events;

Alarm statistical analysis: automatically generate alarm curve graphs and statistical reports;

Equipment process simulation: visually display the gas pretreatment and detection path.

2. Long lifespan and low maintenance

Imported diaphragm pump sampling: Sampling accuracy error<1%, service life of over 50000 hours, maintenance rate less than 0.5%, significantly reducing after-sales costs.

Sensor durability: With a 24-hour continuous working life of over 1 year, it supports hot swappable replacement and reduces downtime.

3. Multiple security protections

Over limit alarm mechanism: When the concentration exceeds the limit, the local alarm light of the device will flash, and the alarm information will be pushed to the platform. The historical alarm records can be traced.

Explosion proof design: Passed Ex d IIB T4 explosion-proof certification, suitable for flammable and explosive scenarios such as petrochemicals.

3、 Application scenario: Full chain coverage of emission monitoring requirements

1. Unorganized emission monitoring

Chemical industrial park boundary: Located at the boundary of the park, it monitors the diffusion trend of TVOC in real time and assists in delineating the scope of pollution impact.

Workshop entrance and exit: locate the source of leakage in the production process and optimize the process flow by combining leak detection monitoring.

Emergency accident monitoring: Quickly respond to leakage accidents and provide real-time concentration data to support emergency decision-making.

2. Organized emission monitoring

Flue/chimney exhaust outlet: installed at the rear of the treatment facility to verify the efficiency of exhaust gas treatment and ensure compliance with emission standards.

Patrol monitoring: Mobile deployment for routine air inspections in the environment, screening potential leakage points.
