Novasina Labswift Portable Precision Water Activity Meter
Portable Precision Water Activity Meter
Portable Water Activity Measurement for Food, Pharma and Quality Control
The Novasina LabSwift-aw is a portable precision water activity meter used to measure aw in food, pharmaceutical, cosmetic and industrial samples. Water activity is a key quality and safety parameter because it helps indicate how much unbound water is available in a product, which can affect microbial stability, shelf life, texture, caking, flowability and formulation consistency.
This instrument is designed for daily quality control and mobile measurements where a compact, easy-to-use aw meter is preferred. It combines a sealed measurement chamber, large LCD display, infrared sample temperature measurement, data logging and an SD card interface, making it practical for production areas, laboratories and field testing.
Portable aw Measurement
The LabSwift-aw is built for users who need reliable water activity testing without a large benchtop instrument. Its rechargeable lithium-ion battery and carrying case make it suitable for measurements at different workstations, production areas or sampling locations.
Food, Pharmaceutical and Cosmetic Applications
Typical applications include water activity testing of bakery products, meat, cheese, powders, spices, confectionery, pet food, pharmaceuticals, cosmetics and other products where moisture availability affects product stability and quality.
Electrolytic Resistive Sensor Technology
The instrument uses an electrolytic resistive water activity sensor with infrared and NTC temperature measurement. This measuring principle is intended to provide stable aw measurement while keeping operation simple for routine users.
Data Logging and SD Card Export
The built-in data logger and SD card interface help users document measurements and transfer records. This is useful for quality control programs, batch records, incoming inspection and product development work.
Calibration and Adjustment
The LabSwift-aw supports checking, testing and adjustment with SAL-T humidity standards. Available adjustment points include 11%, 33%, 53%, 58%, 75%, 84% and 90% relative humidity, depending on the working range and procedure used.
Protected Measuring Chamber
The spring-loaded sealed measuring chamber helps create stable measurement conditions. Optional filters can be used for more demanding samples containing substances such as alcohol, acids, bases or chlorine, helping protect the sensor from contamination.
Q&A
What is the Novasina LabSwift-aw used for?
The Novasina LabSwift-aw is used to measure water activity in food, pharmaceutical, cosmetic and industrial samples for quality control, shelf-life evaluation and product stability checks.What is water activity?
Water activity, or aw, measures the amount of unbound water available in a product. It is different from moisture content and is often used to evaluate microbial risk, texture stability and shelf life.What is the measuring range of the LabSwift-aw?
The LabSwift-aw has a water activity measuring range of 0.030 to 1.000 aw, with a common adjustment range from 0.110 to 0.900 aw.Is the LabSwift-aw portable?
Yes. The LabSwift-aw is a portable water activity meter with a rechargeable lithium-ion battery, compact housing and carrying case options for mobile use.Does the LabSwift-aw have temperature control?
No. The LabSwift-aw does not have active temperature control. It measures sample temperature using infrared and NTC temperature measurement.Can the LabSwift-aw store data?
Yes. The instrument includes a data logger function and SD card interface for storing and transferring measurement records.Which industries use water activity meters?
Water activity meters are used in food production, bakery, meat processing, dairy, pet food, pharmaceuticals, cosmetics, powders, spices and quality control laboratories.Specifications
