Product Description: 10The Type Hengli Constant-Flow Atmospheric Sampler is an instrument for collecting gaseous or vapor samples from the atmosphere. It is mainly composed of a gas pump drive system, control system, operating system, and flow detection system. The control system operates the gas pump drive system according to user commands, and the flow detection system monitors the user-defined flow rate and feeds back to the control system for constant flow control of the pump. When the load in the gas line increases within a certain range, the control system automatically adjusts the flow to the set flow rate, ensuring constant flow and guaranteeing the accuracy of the user's test data.
This instrument boasts compact structure, small size, lightweight, ease of portability, durability, strong load-bearing capacity, stable flow rate, and low noise. It features a liquid crystal digital display for sampling flow rate, cumulative sampling volume, and sampling time. It can be carried while working and is currently one of the more ideal gas constant flow sampling instruments.
