ZR-3720 Waste Gas Dioxin Sampler

Product Introduction
The ZR-3720 Waste Gas Dioxin Sampler is a specialized environmental monitoring instrument designed to collect solid-phase and gas-phase dioxins from industrial exhaust emissions. It is suitable for dioxin sampling in hazardous waste incineration facilities, medical waste incineration plants, cement kilns co-processing hazardous waste, and municipal solid waste incineration facilities.
Featuring a modular design, high-negative-pressure sampling pump, and automatic temperature control system, the ZR-3720 provides reliable sampling under demanding field conditions. Based on the Pitot tube parallel isokinetic sampling principle, it automatically tracks flue gas velocity to maintain accurate isokinetic sampling. Its intelligent control system integrates real-time parameter monitoring, automatic fault protection, data storage, and field reporting, making it suitable for environmental acceptance inspections, regulatory monitoring, and industrial emission testing.

Performance Features
1. Modular Structure: Compact, lightweight design enables convenient transportation, rapid assembly, and on-site operation.
2. High-Performance Sampling Pump: Uses an imported high-negative-pressure, high-flow sampling pump with an Omron variable-frequency controller for continuous operation under demanding conditions.
3. Intelligent Touchscreen: Features a 5.6-inch color touchscreen, Chinese-language menus, intuitive operation, and comprehensive prompts.
4. USB Data Export: Supports USB flash drive data export for convenient storage and management of large volumes of sampling records.
5. Inert Sampling Gas Path: Uses inert materials to minimize contamination. The replaceable titanium sampling tube and multiple titanium nozzle sizes accommodate different operating conditions.
6. Automatic Constant-Temperature Control: Automatically heats and maintains the sampling gas path at the required temperature, supporting reliable sample collection.
7. Reliable Sealing Structure: Optimized connection design helps maintain gas-path airtightness and reduce leakage.
8. Power Interruption Recovery: Automatically saves sampling data and remembers operating status during power interruptions, allowing sampling to resume after power is restored.
9. Built-In Thermal Printer: High-speed, low-noise thermal printing enables convenient on-site report generation.
10. Real-Time Clock: Records accurate sampling dates and times, supported by a backup battery.
11. Automatic Heating and Cooling: Integrated temperature control system provides fast response, high accuracy, and stable operation.
12. Automatic Isokinetic Sampling: Uses Pitot tube parallel isokinetic sampling technology to track flue gas velocity with high accuracy and rapid response.
13. Real-Time Environmental Monitoring: Measures atmospheric pressure and ambient temperature and automatically calculates standard-condition flow rate and sampling volume.
14. Automatic Fault Protection: Continuously monitors sampling conditions and activates protective measures when abnormalities occur.
15. Calibration Data Protection: Password-protected calibration parameters and one-key factory reset help maintain instrument configuration security.
16. Multiple Moisture Measurement Methods: Supports direct input, dry-wet bulb measurement, and condensation methods for determining flue gas moisture content.
17. Automatic Leak Detection: Features automatic gas-path leakage checking to help ensure sampling integrity.

Working Principle
The ZR-3720 Waste Gas Dioxin Sampler operates based on the Pitot tube parallel isokinetic sampling principle. During operation, the instrument measures flue gas velocity and automatically adjusts the sampling flow rate to maintain an isokinetic relationship between the sampling velocity and the flue gas velocity.
The sampling probe collects particulate-bound dioxins, while the sampling system captures gas-phase components through the designated collection arrangement. The sampling gas path uses inert materials and automatic temperature control to minimize contamination and maintain appropriate sampling conditions.
Throughout the process, the instrument continuously monitors sampling parameters, including atmospheric pressure, ambient temperature, and gas flow. It automatically calculates standard-condition flow rates and sampling volumes, records operational data, and provides automatic protection against abnormal conditions.
