The product complies with HJ/T375-2007 Technical Requirements and Detection Methods for Ambient Air Samplers; JJG956-2013 Verification Regulation for Ambient Air Samplers; HJ/T 376-2007 Technical Requirements and Detection Methods for 24-Hour Constant Temperature Automatic Continuous Ambient Air Samplers; Enterprise standard Q/WTH24S-2025 TH-110F Intelligent Ambient Air Sampler.
Application Scope
The TH-110H (constant temperature) ambient air sampler is an intelligent instrument with automatic constant flow, high accuracy, and high reliability, designed and produced according to actual sampling site requirements. The instrument uses a 4.3-inch high-brightness color touch screen as the human-machine interface, with simple operation and reliable performance, fully meeting sampling requirements of environmental monitoring, research institutes, and health and epidemic prevention departments.
Instrument Features
•Uses semiconductor constant temperature technology, with automatic gas sampling maintained at 24±2℃;
•Sampling and drying bottles are placed inside the machine to avoid freezing in winter and inability to sample;
•Both channels have automatic tracking with digital flow display for accurate flow measurement and control;
•Uses microprocessor to automatically control suction flow, achieving automatic constant flow at the set flow rate;
•Uses imported brushless suction pump with low noise and high reliability;
•Full sampling modes available for user selection, with arbitrary setting of sampling parameters;
•Features software calibration function, allowing convenient calibration of parameters such as instrument flow, temperature, and atmospheric pressure via touch screen;
•4.3-inch high-brightness touch color screen for parameter display and operation, reliable and convenient;
•Power failure data preservation function, automatically saves parameters and continues sampling upon power restoration;
•Automatically measures on-site atmospheric pressure, ambient temperature, flow rate, pressure before flowmeter, etc., with automatic compensation for flow changes;
•Sampling flow rate and sampling time can be modified during sampling;
•Automatically accumulates working condition and reference state sampling volumes;
•Two-channel sampling data stored and queried separately, with each channel capable of storing more than 500 groups of data independently;
•The instrument has overload protection function;
•Optional printer for printing current or historical sampling data;
•External DC power interface;
•The instrument is small in size, light in weight, and easy to carry.
