Ohaus Moisture Analysers

Ohaus Moisture Analysers – Fast, Accurate Moisture Content Testing for QC & Production

Ohaus moisture analysers combine precision weighing with halogen 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, they are essential instruments for quality control, incoming goods testing, process monitoring, and compliance across food production, pharmaceuticals, plastics, chemicals, and agriculture.

Ohaus has over 100 years of weighing instrument expertise, and their moisture analyser range reflects this in the quality of the weighing system at the core of each instrument. Halogen heating provides rapid, uniform sample drying with precise temperature control, while the high-resolution weighing system calculates moisture percentage in real time throughout the drying cycle. 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, with GLP-compliant output including date, time, and instrument ID for full measurement traceability.

Frequently Asked Questions

How does an Ohaus moisture analyser compare to oven drying?

Traditional oven drying (loss on drying, LOD) can take 1–4 hours per sample. An Ohaus 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.

What sample size is recommended for Ohaus moisture analysers?

Most Ohaus 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. Smaller samples dry faster but may introduce greater variability. Refer to the instrument’s application guide or contact our team for guidance on optimal sample size for your specific material.

Are Ohaus moisture analysers GLP compliant?

Yes. Ohaus moisture analysers produce GLP-compliant printed records including date, time, instrument ID, method parameters, and results. For GMP environments requiring user login, audit trail, and method lock features, check individual model specifications or contact our team for guidance.

Can Ohaus moisture analysers connect to LIMS or laboratory software?

Yes. Most models include RS-232 and USB connectivity for direct data transfer to LIMS, spreadsheet software, and data logging applications. Contact us for compatibility advice specific to your laboratory software environment.

Are UKAS calibration certificates available?

Yes. UKAS-traceable calibration certificates are available on request for all Ohaus moisture analysers. Routine verification using certified temperature standards and reference weights is also recommended — contact our team for calibration and service support.
