Model 20 2030 -Medium Flow Ambient Air Particulate

• HJ 93-2013 Technical requirements and test methods for ambient air particulate matter (PM 10 and PM 2.5 )
• HJ/T 374-2007 Technical requirements and test methods for total suspended particulate sampler
• HJ 618-2011 ambient air the PM 10 and the PM 2.5 Gravimetric method
• JJG 943-2011 Total Suspended Particle Sampler

Control System

• Unique LOCS system design to capture total suspended particulates (TSP) or respirable particulates (PM10) or fine particulates (PM2.5 optional) in ambient air
• Automatic sampling and flow control: high-precision, corrosion-resistant electronic flowmeter, micro-computer system to detect sampling flow, automatically compensate for flow changes caused by voltage fluctuations and resistance, temperature changes
• Adopting the induced ambient temperature detection module to greatly reduce the environmental temperature measurement error and further improve the flow accuracy
• Automatically calculate the cumulative sampling volume, and simultaneously convert the standard volume and reference volume according to air pressure and temperature.
• The sampling process will automatically save the working data after power failure, and the sampling can be resumed after the call.

Power system

• Precision DS. Sampling pump, corrosion-resistant, ultra-low noise, continuous operation and maintenance-free, adapt to various working conditions, with overload protection
• Built-in filter, with overload, low flow self-protection program, can effectively protect the gas path and sampling pump

 Control system

• Wide temperature and high brightness TC-OLED display, suitable for alpine areas, popular software display interface, achieving good human-computer interaction
• Can realize various sampling methods such as immediate sampling, timing sampling, equal interval sampling, etc.
• Atmospheric pressure can be input and measured, suitable for low pressure environment
• It can provide the user with the current date and time at any time, which is convenient for users to operate.
• If the sampler does not reach the set flow within a certain period of time due to excessive resistance, the sampler will automatically stop the protection.
• Intelligent software calibration function
• Built-in large-capacity memory, sample data can be stored, consulted, exported, printed
• Built-in Bluetooth module for easy access to portable Bluetooth printers for real-time data
• Provide USB interface to export sampled data files and support upgrade of instrument motherboard program
• Retain the IoT module interface to expand networking capabilities
• Optional built-in lithium battery (built-in charging module, no external charger required)

 
other

• The appearance is designed by L-Ergo, the style is novel, the unique sealing structure is effective against rain and snow, and is more suitable for field work.

• TSP/PM10/PM2.5 (optional) sampling head is made of aluminum alloy, antistatic adsorption
