The instrument uses filter membrane weighing method to capture total suspended particulates (TSP) and inhalable particulates (PM 10 ) or fine particulate matter (PM 2.5 optional) in the ambient atmosphere; the ambient atmosphere and indoor air are collected by solution absorption method. A must-have instrument for polluting gas components (SO 2 , NO X ,  etc.). It can be used for environmental or health, labor, safety, military, scientific research, education and other departments for routine or emergency monitoring of particulate matter, gaseous substances and aerosols.

Control System

  • Laois system design should be unique, it can gather ambient air SO 2 , NO X-  like gaseous pollutants and the TSP, the PM 10 and the PM 2.5 dust contaminants
  • 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
  • The cumulative sampling volume is automatically calculated, and the reference sampling volume (25°C, 101.325kPa reference state volume, factory default) or standard sampling volume is converted according to the 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 core pump, corrosion-resistant, ultra-low noise, continuous operation, maintenance-free, large load capacity, long service life, adapt to various working conditions, with overload protection
  • High-efficiency anti-back suction dryer design, effectively preventing the absorption of the absorption liquid caused by misoperation and enhancing the safety of the instrument
  • High-quality filter filter with overload and low-flow self-protection program to 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
  • Atmospheric sampling A/B two-way design, flexible sampling method, can be controlled separately
  • Can realize various sampling modes such as instant sampling, timing sampling, interval sampling, etc.
  • Atmospheric pressure can be input and measured, suitable for low pressure environment
  • Intelligent software calibration function
  • Built-in large-capacity memory, sample data can be stored, consulted, exported, printed
  • Retain Bluetooth module interface for easy connection 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

 Other

  • Conventional and constant current type: The integrated thermostat intelligent constant temperature design can realize atmospheric sampling under constant temperature conditions. The high-efficiency anti-back suction dryer, air guiding tube and absorption bottle are placed in the incubator to prevent air passage icing. Normal sampling under high cold conditions
  • Lithium-ion type: The integrated thermostat intelligent constant temperature design can realize atmospheric sampling under constant temperature conditions (divided into two types: constant temperature type and anti-freezing type). High-efficiency anti-back suction dryer, air guiding tube and absorption bottle are placed in the incubator. Can prevent airway icing to ensure normal sampling under high cold conditions
  • Mini type: one-piece incubator intelligent antifreeze design, high-efficiency anti-back suction dryer, air pipe, absorption bottle, etc. are placed in the incubator to prevent air passage icing to ensure normal sampling under high cold conditions
  • Lithium type: Built-in large-capacity lithium battery pack (26.4Ah), can be used for a long time without AC power
  • Lithium type: built-in charging module, reducing the number of accessories, easy to carry and manage
  • Rear tank drainage channel design for quick draining of liquid in the tank
  • Brown thermostat cover design for secondary light protection
  • Mini is 15% smaller than other models, lighter and more portable
  • 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/PM 10 /PM 2.5 (optional) sampling head made of aluminum alloy, antistatic adsorption
  • High quality and stable geological tripod for customers to choose from, suitable for sampling in harsh climates such as high winds
