1. Overview

The LB-2036 Comprehensive Atmospheric Sampler integrates atmospheric gas sampling, medium flow particulate matter sampling, and environmental air fluoride sampling. Gas sampling uses the solution absorption method to collect various gaseous substances in the ambient atmosphere and indoor air; particulate matter sampling employs the filter membrane weighing method to capture particulates in the ambient atmosphere. Fluoride in the ambient air is collected using the double-membrane method. It is widely applicable in environmental monitoring, labor protection, scientific research institutions, and other fields for sampling gaseous substances, particulates, and fluorides in ambient air.

3. Key Features

1) Compact, lightweight, easy to install and carry. The cutter is made of aluminum alloy material with static-proof adhesion.

2) Can perform atmospheric gas sampling, particulate matter sampling, and fluoride sampling individually or simultaneously, multi-functional in one machine.

3) Air, particulate matter, and fluoride samplings all use brushless DC motors, enabling continuous long-term operation.

4) The machine is equipped with microcomputer control for time, temperature, flow rate, and other parameters, automatically adjusting flow fluctuations caused by voltage and resistance changes, ensuring the accuracy of the sampled data.

5) Features simultaneous sampling, individual sampling, multiple sampling, next-day sampling, and cyclic sampling options.

6) Features a wide-temperature display screen with a broad operating temperature range, suitable for various environments.

7) Optional external heater for atmospheric sampling is available for normal operation in cold northern regions.

8) Automatically accumulates sampling volume, automatically converts to standard condition sampling volume.

9) Automatically save the sampling volume, standard condition sampling volume, and sampling time, etc., and can be exported via USB flash drive.

10) The machine will automatically shut down for protection if the set flow rate of the instrument is not reached within a certain time after sampling is initiated.

11) Automatically detects power supply status; during sampling, power outages will automatically save sample data.

12) Features two modes: automatically resumes sampling after power return with or without deduction of downtime.

13) Equipped with a real-time clock for user convenience.

14) The Maintenance Menu is password-protected to ensure data security.

15) Intelligent design allows calibration of instrument parameters such as flow rate, pressure, and temperature through the keyboard.
