Instrument Introduction

According to Anderson's impact principle, when air containing microbial particles enters the sampling port, microbial particles of different sizes collide with the corresponding sampling medium surfaces according to their aerodynamic characteristics. Different air velocities can capture microorganisms of different diameters. Our company designs two models, impact type and slit type, to measure airborne bacteria and aerosols in the air. To meet different experimental needs.

main features

The parameter display adopts a dot matrix LCD screen, which is intuitive and convenient to operate;

2. Equipped with high-capacity nickel hydrogen batteries for longer usage time;

The HAS-100D sampling head can rotate flexibly, and the rotation speed can be adjusted as needed for more uniform sampling;

4. Display battery level without external power supply, which can remind users to charge in a timely manner;

Turn off the backlight of the LCD screen 30 seconds after the last button press. If it automatically shuts down after 5 minutes in non sampling mode, it saves power;

6 portable sampling heads can be removed for high-temperature disinfection;

7 optional brackets, with adjustable collection height up to 1.5m;

100A has two placement modes: horizontal and vertical;

8 has a startup delay function to eliminate the impact of environmental changes on the detection results;

9 can be quantified using volume digital display;

Using laser drilling technology to drill holes on the turntable, ensuring consistency in each hole;

11. Meet the requirements of GB/T18883-2002 air bacterial total detection instrument.

Procurement Guide

Our company's main recommended model is HAS-10B, which is easy to carry and can be equipped with a bracket. The collection height can reach up to 1.5 meters, which can meet the general outdoor air sampling requirements and has a high cost-effectiveness. The HAS-100D culture dish can be rotated to make sampling more uniform. Other performance is the same as HAS-10B. HAS-100A cannot be connected to a bracket, and its other characteristics are the same as HAS-100B. All three instruments are suitable for detecting indoor air microorganisms. The 100C is a slit type with strong selectivity, and the flow rate is 28.3L/min, which is equivalent to the 7th level of Anderson's impact principle. It is suitable for capturing microorganisms with a size of 10-0.4 μ m. HAS-2A and HAS-6A are designed for second and sixth level air sampling, respectively, based on the principle of human respiration. They have strong selectivity and are suitable for studying the pollution of various parts of the human respiratory organs caused by atmospheric pollution, namely the particle size distribution and concentration of human respiratory organs.
