Humidity, Dew Point and Moisture measurements Try Vaisala's Humidity Calculator Water (H2O) can present itself in three different forms: solid (ice), liquid (water), and gas (humidity). Humidity is an invisible gas that can be measured and defined with different parameters. Relative humidity indicates the present state relative to maximum humidity in a given temperature. Dew point temperature indicates the temperature to which air needs to be cooled in order to reach condensation. For industrial-scale manufacturing, controlling these parameters is a must for good quality end-products and efficient manufacturing processes. Get to know Vaisala’s reliable and durable measurement solutions for humidity, dew point, and moisture. Humidity Humidity is measured in many air control applications, where the relative humidity is for the most part over 10 %. Relative humidity (RH) is a measure of the water vapor content of air. For more information, read the article what relative humidity is and why it is important. Find humidity measurement products by typical applications: test chambers, building automation and HVAC, spray drying, paint booths, biogas production, and bio-decontamination. HUMIDITY GUIDE FOR SMART INDUSTRIES White paper: Controlling high-humidity applications with dew point temperature This white paper is a vital resource for anyone aiming to maintain a controlled environment in a high-humidity application. Download the White Paper Dew Point Dew point measurements are needed when controlling air in dry processes, usually with relative humidity below 10 %. For more information about dew point, read the article "What is dew point and how to measure it?". Find dew point measurement products by typical application: compressed air drying, fluid bed drying, 3D printing, lithium-ion battery manufacturing, and semiconductor manufacturing. Choose the right instrument for humidity and dew point Moisture Avoiding moisture in concrete or structures requires high quality measurement. Moisture measurements are essential also when there is a need to protect engines or to ensure high-quality oil with moisture in oil measurements Moisture in Oil (MiO) measurement Dew point temperature or frost point temperature? Select the correct parameter output to low humidity applicationsSometimes, the terms are mixed in the industrial language, and dew point temperature might actually refer to frost point temperature. Read Vaisala's recommendations here (PDF) Humidity Control in Hazardous Locations Humidity control is critical in many spaces where flammable or explosive materials such as fuels, chemicals, explosives are being stored. These spaces are designated as hazardous due to potentially explosive atmospheres. They require specially designed and approved instruments for safe operation. Vaisala's intrinsically safe humidity instrument for hazardous locations is the HMT370EX Humidity and Temperature Transmitter. Learn more High-quality measurement benefits Energy-savings Especially in drying applications, accurate humidity measurement can bring significant savings in both energy and costs. By knowing the humidity level you can, for example, avoid over-drying and heating the air too much. End-product quality Exact humidity data helps you optimize your production process and facilities, as well as make sure that the humidity level in your end-products is just right. Depending on the product, it can mean for example longer shelf life or improved stability. Safety & well-being Humidity control in facilities and moisture control in structures improve both safety and well-being when the air is optimized for breathing and the formation of mold is avoided. Controlling process humidity is also crucial for safety and well-being. Vaisala humidity calculator Relative humidity, absolute humidity, wet-bulb temperature, enthalpy, water concentration, and many more. Humidity calculations and conversions made easy. Humidity Calculator Trusted HUMICAP® and DRYCAP® technologies We have been the industry leader in humidity measurements for over 40 years. Our solutions are suitable also for very demanding measurement conditions. Vaisala’s HUMICAP® and DRYCAP® technologies have been trusted for decades due to their accuracy and stability. Humidity and Multigas Measurements with CARBOCAP® and PEROXCAP® With our continuous research and development efforts, we have been able to combine humidity measurement possibilities also with other parameters and technologies. We developed the CARBOCAP® technology originally for measuring CO2, but the technology is well suited also for optical humidity and methane measurements in biogas applications. Vaisala’s PEROXCAP® technology was developed for measuring humidity, vaporized hydrogen peroxide and temperature for easy validation of hydrogen peroxide bio-decontamination of isolators and facilities.
