The product complies with HJ/T376-2007 Technical Requirements and Detection Methods for 24-Hour Constant Temperature Automatic Continuous Ambient Air Samplers; JJG956-2013 Verification Regulation for Ambient Air Samplers; Enterprise standard Q/WTH14Y-2023 TH-3000 Series 24-Hour Constant Temperature Automatic Continuous Ambient Air Samplers.
Application Scope
The TH-3000BVI portable continuous constant temperature ambient air sampler is the latest portable on-site ambient air sampler developed by our company. The sampler is designed in accordance with the latest standards of the Ministry of Environmental Protection, incorporating extensive expert advice and valuable user feedback, combined with features of the TH-3000 series. The TH-3000BVI sampler is suitable for collecting various harmful gas components such as SO₂ and NOₓ in ambient air.
Instrument Features
•The instrument can collect four gas samples simultaneously, with each channel independently controlled;
•Uses industrial-grade electronic (semiconductor) constant temperature technology for four-channel gas sampling, with dual temperature measurement and full-wrap automatic constant temperature for absorption bottles;
•Combines microporous constant flow gas dynamics principle with feedback stabilization and other methods for automatic constant flow control;
•Multiple flexible sampling modes: conventional mode, interval mode, constant volume mode, scientific mode, etc.;
•Automatically calculates standard condition sampling volume, supports timed, interval sampling, with multiple sampling volume accumulation function and state conversion;
•Uses low-noise, high-performance imported DC brushless gas micro-pump;
•Built-in large-capacity memory for permanent storage of at least 50 groups of sampling data;
•Real-time clock display, power failure self-recovery sampling, with selectable power failure sampling compensation or non-compensation function;
•Software calibration function with user password protection;
•Power failure and power restoration log recording, with query and wireless printing functions;
•OLED wide-temperature LCD Chinese character display screen, ensuring normal operation in low illumination and low temperature;
•Automatically measures on-site atmospheric pressure and temperature for automatic participation in gas state conversion;
•Four-channel gas sampling can use electronic flowmeter reading version.
