About This Product
■Summary
We have a wide range of lineups, including a portable handheld type that runs on a rechargeable battery, a desktop type that can connect up to 4 measurement stations, and a type with constant temperature function. We can perform highly reliable water activity measurements tailored to your needs.
The growth of microorganisms is mainly affected by temperature, moisture, nutrients, oxygen, and pH. Among these, moisture that can be used by microorganisms (free water) is an important factor that is closely related to the growth of microorganisms in order to prevent spoilage and spoilage, which affects the shelf life of products. Therefore, water activity (Aw) is used as an indicator of the percentage of free water contained in foods. Water activity (Aw) can be determined by measuring the equilibrium relative humidity (ERH) in a closed container.
■Lineup according to application
We have a wide variety of water activity measuring devices equipped with Rotronic measuring stations that employ capacitance sensors that have high accuracy, fast response times, and are excellent for low-humidity measurements, so that users can choose the device that best suits their purpose, such as quality control in food, pharmaceuticals, cosmetics, and other fields, as well as preservation of powders, tablets, seeds, etc. We offer easy-to-use systems by combining measuring stations (sensor probes), indicators, and other accessories.
■Features
This is an integrated model equipped with a temperature adjustment function (settable range: 1 to 40℃) and a measurement station. It is not easily affected by changes in the external temperature environment, so it is recommended for those who have difficulty setting the temperature of the measurement environment, or for those who have been using it in conjunction with a constant temperature machine.
■Highly reliable calibration
Rotronic's humidity standards are supplied in ampoules. Rotronic is accredited by the Swiss National Institute of Metrology (EAM) and the Swiss National Institute for Calibration and Certification (SAS) as an official calibration laboratory for relative humidity. A SAS calibration certificate is attached to the calibration set, so you can perform highly reliable calibration yourself.
