Radwag Moisture Analysers – Fast, Accurate Moisture Content Determination for QC & Production
Radwag moisture analysers combine precision weighing with halogen or infrared heating technology to determine the moisture content of samples quickly and accurately — delivering results in minutes rather than the hours required by traditional oven-drying methods. Manufactured in Poland by Radwag — one of Europe’s leading precision weighing instrument manufacturers — their moisture analyser range is designed for quality control, incoming goods testing, process monitoring, and regulatory compliance across food production, pharmaceuticals, plastics, chemicals, and agriculture.
Radwag moisture analysers are built on the same high-resolution weighing platform technology found across their laboratory balance range, ensuring the accuracy and repeatability of the moisture measurement is underpinned by a precision weighing system rather than a basic load cell. Programmable drying programmes allow users to set temperature, drying time, and automatic shut-off criteria — either time-based or when the rate of weight loss falls below a defined threshold — making the instrument adaptable to a wide range of materials and testing protocols. Results are displayed as moisture %, dry weight, wet weight, and drying curve on a colour touchscreen, with GLP-compliant output including date, time, and instrument ID for full measurement traceability. Advanced models include user management, audit trail, and 21 CFR Part 11 compliant data integrity features for regulated pharmaceutical and GMP environments.

Frequently Asked Questions
How does a Radwag moisture analyser compare to oven drying?
Traditional oven drying (loss on drying, LOD) can take 1–4 hours per sample. A Radwag moisture analyser typically delivers results in 5–15 minutes, making it far more practical for routine QC and production environments. Results are generally comparable to oven methods, though correlation testing between the two methods is recommended when validating the analyser against an established oven-drying procedure.
Are Radwag moisture analysers GLP and GMP compliant?
Yes. Radwag moisture analysers produce GLP-compliant printed records including date, time, instrument ID, method parameters, and results. Advanced models include user login, audit trail, method lock, and 21 CFR Part 11 compliant data integrity features for regulated pharmaceutical and GMP environments. Contact our team for guidance on the appropriate model for your regulatory requirements.
Can Radwag moisture analysers connect to LIMS or laboratory software?
Yes. Most models include RS-232, USB, and Ethernet connectivity for direct data transfer to LIMS, spreadsheet software, and data logging applications. Contact us for compatibility advice specific to your laboratory software environment.
What sample size is recommended?
Most Radwag moisture analysers work best with sample sizes of 2–10 g, though this varies by material. Larger samples improve statistical representativeness but take longer to dry. Refer to the instrument’s application guide or contact our team for guidance on optimal sample size for your specific material.
Are UKAS calibration certificates available?
Yes. UKAS-traceable calibration certificates are available on request for all Radwag moisture analysers. Routine verification using certified temperature standards and reference weights is also recommended — contact our team for calibration and service support.
