PTM500 Gas Dilution and Mixing Device with 1:2000 Ratio, 10-inch Touch Screen for Air Quality Monitor Calibration
The PTM500 dynamic gas dilution and mixing device delivers precise gas concentration preparation with flexible dilution ratios from 1:1 to 1:2000, meeting stringent testing and calibration requirements. This instrument is widely used for multi-point calibration, linear verification, and performance evaluation of laboratory chromatography systems, portable gas chromatography-mass spectrometry equipment, air/smoke monitoring instruments, and gas alarms.
- High Precision: Linear correlation coefficient of flow rate reaches 0.9999 for accurate dilution
- High Dilution Ratio: Capable of 1:2000 dilution ratio to flexibly meet diverse requirements
- Inert Flow Path: Complete flow path silanization reduces adsorption and residue
- Low Power Consumption: Battery life exceeds 6 hours for stable, worry-free operation
- Intelligent Reminder: Built-in alerts for timely operation and maintenance
- Programmable Output: Supports multi-stage programmable output with automatic dilution ratio and flow rate adjustment
- Flexible Power Supply: Built-in battery compatible with AC and DC power for multiple scenarios
- Historical Data Storage: Stores historical data for easy backtracking and analysis
- Data Export: Supports printing and USB export for convenient processing and analysis
- Pressure Control: Electronic adjustment of mixed gas output pressure for automatic sampling of chromatographic analyzers (optional)
This instrument is used for testing and calibration of gas analysis instruments, reactor gas supply, sample gas debugging, and gas mixture synthesis. It can pre-set output gas concentration and duration, automatically completing gas matching experiments. Applications include compliance with environmental testing standards such as HJ1006-2018, HJ 604-2017, HJ 1261-2022, and HJ57-2017 for various gas analysis and monitoring requirements.
