Leading Manufacturer of Dewpoint Meters and Hygrometers for Compressed Air and Industrial Gases

Over 30 Years Experience
World Leading Sensor
Distributors Worldwide

Alpha Moisture Systems is a leading dew point meter and dew point instrumentation manufacturer. We have been market-leaders in trace moisture measurement technology for over 30 years. We engineer and manufacture a unique ultra-high capacitance sensor which reliably measures trace moisture content in gases and compressed air. Our sensors measure moisture content from -110 °C to +20 °C dew point, i.e. nearly 1 part per billion to 23,000 parts per million.

Our sensor is the heart of our products, delivering unsurpassed sensitivity, speed of response, accuracy, repeatability, stability and long service life. Our ISO9001 accredited facility in Bradford, England, manufactures dew point transmitters and sampling systems for continuous dew point measurement. We offer portable handheld hygrometers suitable for general and hazardous applications. Instrument calibration is traceable to the National Physical Laboratory and provided by our fully equipped calibration laboratory. If you require a dewpoint calibration capability in your own facility, we can manufacture complete calibration systems to suit your needs.

Our products are everywhere, safeguarding life, empowering manufacturing, protecting our planet and exploring the universe.

Trace moisture measurement is highly specialised and often misunderstood. We maintain our position as a global leader through our single-minded obsession with engineering excellence and a commitment to helping our customers overcome their moisture measurement challenges. Our team includes experienced technical specialists who ensure our customers’ requirements are fully understood and accommodated. We provide innovative solutions that are cost-effective, on time and satisfy the most rigorous and demanding regulations.
