Dew Point Calibration System Dew Point Generator Humidity Generator Dew Point Verification System Dew Point Meter

Overview

In this Dew Point Verification System, the humidity generator regulates humidity based on the principle of the divided flow method. By varying the mixing ratios of dry and humid gas streams, gases with different dew point temperatures can be generated. Depending on specific requirements, this method allows for multi-stage flow division configurations to produce a gas source with the desired dew point value. The system is capable of continuously generating humid gas with dew points ranging from -80°C to +20°C, with an adjustable flow rate of 0 to 10 L/min.

Comprising units such as an air compressor, dry gas generator, dew point generator, and flow control valves, the system meets the operational requirements of several key standards: GB/T 5832.2-2016 (*Gas Analysis—Determination of Trace Moisture—Part 2: Dew Point Method*), JJG 499-2004 (*Verification Regulation of Precision Dew Point Meters*), and JJF 1272-2011 (*Calibration Specification for Capacitive Dew Point Meters*).

The entire system features a compact structure and a small footprint, while offering a high degree of automation. It is suitable for a wide range of industries, including metrology, higher education, scientific research, dew point meter manufacturing, electric power, petrochemicals, natural gas, steel, and microelectronics.

Key Features

• Integrated chassis design for convenient operation;
• The gas source, dry gas generator, dew point generator, and dew point meter units can be independently detached and assembled, allowing for flexible configuration based on specific needs;
• The total flow rate is adjustable from 0 to 10 L/min, allowing users to regulate the flow according to the number of devices under verification;
• The dry gas generator is capable of stably outputting dry gas with a dew point temperature of < -80°C;
• The dew point generator utilizes high-precision, high-stability mass flow controllers to mix the dry and humid gas streams, ensuring a stable gas output;
• System operation is managed via a large 7-inch touchscreen display, providing a simple and user-friendly human-machine interface.
