The ADP24H Handheld Dew Point Meter is specially engineered for compressed air systems, gas quality testing, plastic dryers, additive manufacturing, and OEM applications. Equipped with a USB data logging system, it records readings automatically in CSV format, allowing easy analysis and long-term monitoring of moisture conditions in industrial air and gas systems.
This portable and user-friendly device provides real-time dew point readings with high precision, helping industries maintain consistent air quality and prevent moisture-related damage. Its rugged design, long battery life, and digital display make it suitable for both field and laboratory use. Designed for reliability and versatility, the ADP24H ensures stable performance even in harsh environments where moisture control is critical for process efficiency and equipment safety.
What is the typical range of dew point temperatures to be found in compressed air?
Dew point temperatures in compressed air range from ambient down to -80 °C (-112 °F), sometimes lower in special cases. Compressor systems without air drying capability tend to produce compressed air that is saturated at ambient temperature. Systems with refrigerant dryers pass the compressed air through some sort of cooled heat exchanger, causing water to condense out of the air stream. These systems typically produce air with a dew point no lower than 5 °C (23 °F). Desiccant drying systems absorb water vapor from the air stream and can produce air with a dew point of -40 °C (-40 °F) and drier if required.
What are the standards for the quality of compressed air?
ISO8573.1 is an international standard that specifies the quality of compressed air. The standard defines limits for three categories of air quality:
* Maximum particle size for any remaining particles
* Maximum allowable dew point temperature
* Maximum remaining oil content
Each category is given a quality class number between 1 and 6 according to the reference values shown in the table below. As an example, a system that conforms to ISO8573.1 and is rated for class 1.1.1 will provide air with a dew point no higher than -70 °C (-94 °F). All remaining particles in the air will be 0.1 um or smaller, and the maximum oil content will be 0.01 mg/m3. There are other standards for compressed air quality, such as ANSI/ISA- 7.0.01-1996 for instrument air.

Frequently Asked Questions (FAQs)
What is a Dew Point Meter?
A Dew Point Meter measures the temperature at which moisture in a gas begins to condense into liquid water. It helps determine the moisture content or dryness level of compressed air or other gases.
What is the ADP24H Handheld Dew Point Meter?
The ADP24H is a microprocessor-based portable dew point meter with a USB data logging system, capable of recording and exporting data in CSV format for easy tracking and analysis.
Why is dew point measurement important in compressed air systems?
Knowing the dew point ensures that condensation does not form inside air lines, tools, or machinery. High dew points can cause corrosion, freezing, and malfunction, while controlled dew points improve system efficiency and product quality.
What industries use the Handheld Dew Point Meter?
Common applications include:
-
Compressed air drying systems
-
Plastic dryers and extrusion lines
-
Additive manufacturing (3D printing)
-
Pharmaceutical and medical air monitoring
-
Industrial gas generation and distribution systems
How does the ADP24H measure dew point?
It uses a high-precision sensor and internal microprocessor to measure humidity and temperature, then calculates the dew point accurately. The digital system ensures fast response and high repeatability.
How does USB Data Logging help?
The built-in USB data logger automatically stores readings in a CSV file, allowing easy transfer to a computer for graphing, analysis, and long-term record keeping.
What are the main benefits of dew point monitoring?
It helps maintain dry, clean air or gas, preventing condensation, corrosion, and contamination. Dew point monitoring ensures longer equipment life and better product quality in moisture-sensitive processes.
Who manufactures this instrument?
The ADP24H Handheld Dew Point Meter is designed and manufactured by Aranka Instruments LLP, an ISO 9001-certified and CE-approved company based in Ahmedabad, Gujarat, specializing in industrial process and analytical instruments.
