This article explores the importance of moisture measurement, the key technologies behind Alpha Moisture Systems, their flagship products, and the industries that benefit from their solutions.
Understanding Moisture Measurement and Its Industrial Importance
Moisture content in gases and liquids may seem insignificant, but in technical and industrial settings, it can have far-reaching consequences. Excess moisture can lead to corrosion, electrical failures, product spoilage, inefficiencies in combustion, and degradation of sensitive materials.
For example:
- In natural gas, high moisture levels can cause pipeline corrosion or hydrate formation.
- In pharmaceuticals, moisture can alter the chemical stability of drugs.
- In electronics, humidity can cause short circuits or reduce product lifespan.
- In food packaging, moisture affects shelf life and microbial growth.
Precise moisture measurement, often expressed in terms of dew point, parts per million (ppm), or relative humidity (%RH), is therefore essential for maintaining quality, safety, and efficiency.

Key Product Categories by Alpha Moisture Systems
Alpha Moisture Systems offers a diverse range of products tailored for both portable and fixed installation applications. Here’s a closer look at their main offerings:
Portable Dew Point Meters
One of the most popular solutions in Dew Point Analyzers’ catalog is their line of portable dew point hygrometers, such as the Model PDM75 and PDM300.
These handheld devices allow technicians to measure moisture levels in compressed air, natural gas, and other non-corrosive gases on the spot. Key features include:
- Fast response times
- Long battery life
- Compact and durable design
- Easy calibration and maintenance
- Wide measurement range (-100°C to +20°C dew point)
These instruments are ideal for field use where convenience, speed, and precision are required without sacrificing performance.
Fixed Online Moisture Analyzers
For continuous monitoring in production lines or critical infrastructure, Dew Point Analyzers offers fixed dew point analyzers such as the AquaX series.
These systems are designed for permanent installation and provide real-time data to SCADA systems or control rooms. Features include:
- 4–20 mA output for integration
- Alarm systems for high-moisture detection
- Sensor protection and automatic calibration
- Stainless steel sampling systems
They are widely used in gas drying plants, glove boxes, air separation units, and petrochemical plants, where 24/7 monitoring is essential.
Sample Conditioning Systems
Accurate moisture measurement depends not just on the sensor but also on the condition of the sample gas. Dew Point Analyzers provides custom sample conditioning systems that ensure consistent flow, pressure regulation, and temperature control.
These systems include filters, flow meters, pressure regulators, and coolers. They’re essential for maintaining sensor accuracy and extending instrument lifespan in harsh industrial environments.
Dew Point Transmitters and Sensors
For OEM integration or compact setups, Dew Point Analyzers offers dew point transmitters and digital sensors. These miniature devices are designed for space-constrained applications or for integration into machinery.
Some of the key advantages of their sensors include:
- High accuracy ±2°C dew point
- Rugged design with stainless steel body
- Fast response to moisture changes
- Configurable output (0–10V, 4–20mA, RS485)
These transmitters are widely used in laser cutting systems, air compressors, and environmental chambers.
Industry Applications of Alpha Moisture Systems
Alpha Moisture Systems has built long-standing relationships with clients across various sectors. Their equipment is designed to perform in even the most demanding environments:
Oil and Gas
Moisture measurement in natural gas is essential to prevent hydrate formation, corrosion, and compressor damage. Dew Point Analyzers provides ATEX-certified equipment suitable for hazardous locations and pipeline testing.
Pharmaceutical and Medical
Cleanrooms and pharmaceutical manufacturing facilities require strict humidity control. Alpha’s analyzers help ensure compliance with GMP and regulatory standards, maintaining product integrity and stability.
Electronics and Semiconductors
Semiconductor manufacturing is extremely sensitive to moisture. Alpha’s fixed analyzers provide real-time dew point readings to maintain dry gas environments during chip production and packaging.
Food and Beverage
In food processing and packaging, humidity must be monitored to prevent spoilage, microbial growth, or package deformation. Moisture analyzers ensure the right conditions are maintained throughout production.
Power Generation
Power plants often rely on dry gases for turbines and transformers. Moisture can lead to insulation failure and corrosion. Alpha’s instruments are used for monitoring hydrogen-cooled generators and SF6 gas systems.
Air and Gas Drying
Whether it’s desiccant dryers, refrigerated dryers, or PSA systems, Alpha’s instruments verify that the drying systems are performing effectively and ensure gases meet ISO standards for purity and dryness.
Why Dew Point Is the Preferred Measurement
While moisture content can be expressed in ppm or %RH, dew point is the most widely used parameter for industrial moisture measurement. It represents the temperature at which vapor condenses into liquid at a constant pressure.
Why dew point?
- It offers an absolute measure independent of pressure fluctuations
- It’s easy to interpret—lower dew point = drier gas
- It’s widely accepted in standards (e.g., ISO 8573 for compressed air)
- It correlates well with process reliability and safety
Alpha Moisture Systems specializes in dew point measurement and calibrates all its sensors accordingly, ensuring compliance with international benchmarks.
Calibration and After-Sales Support
Accurate moisture measurement requires regular calibration. Dew Point Analyzers offers in-house calibration services traceable to national standards. Clients can send their devices for recalibration, receive certificates, and maintain confidence in their data integrity.
Additionally, the company provides:
- Free technical support
- Installation guidance
- Customized system design
- Spare parts and accessories
- Global shipping and distributor network
This commitment to service ensures that customers get long-term value from their investment.
