The DW-18A Intelligent Atmospheric Sampler is an automatic atmospheric sampler that, based on the original manual control, newly incorporates microcomputer-controlled startup, shutdown, and countdown functions.

This instrument is widely used for environmental health monitoring, occupational health monitoring, indoor environment, and scientific research, for collecting samples of toxic substances. It features the latest microcomputer chip control technology, an integrated high-capacity rechargeable lithium battery, long sampling time, stable flow rate, easy operation, high timing accuracy, durability, and compatibility with both AC and DC power sources. It offers convenient and quick selection of countdown times from 1 to 99 hours and 59 minutes, and automatically shuts off power when stopped. It is considered one of the more ideal samplers in the domestic market for sampling instruments.
