Autoclave & Sterilization Validation Data Loggers

Autoclave and steriliser validation demands data loggers that survive repeated high-temperature, high-pressure, saturated-steam cycles while recording with laboratory-grade accuracy. Pacific Sensor Technologies supplies a complete range of autoclave validation data loggers — from single submersible temperature and pressure loggers rated to 140°C and IP68, through to multi-channel validation kits bundled with reporting software — to help hospitals, sterile-services departments, pharmaceutical manufacturers and laboratories across Australia prove their sterilisation processes meet standard.

Every logger is backed by NATA-endorsed calibration and ISO 9001:2015 quality systems, so your validation data stands up to audit. Whether you need to qualify a single benchtop autoclave or run a full thermal validation across a fleet of sterilisers, you’ll find a configuration below — or talk to our team for a tailored kit.

Frequently Asked Questions

An autoclave validation data logger is a rugged, high-temperature recorder placed inside an autoclave or steriliser to capture temperature (and often pressure) throughout a cycle. The logged data proves the load reached and held sterilisation conditions, providing the objective evidence required for validation and compliance.

Autoclaves typically run at 121°C and 134°C. A suitable validation logger should be rated to at least 140°C and be fully submersible (IP68) so it survives saturated steam and condensate. Our MadgeTech HiTemp140 range, for example, is built specifically for these conditions.

For full steam-steriliser validation, yes — measuring pressure alongside temperature confirms saturated-steam conditions and helps detect air pockets or non-condensable gases. You can run a HiTemp140 temperature logger and a PR140 pressure logger together and combine the two graphs into one in MadgeTech 4 software.

In Australia, autoclave validation and reprocessing are governed by AS 5369:2023 (for dental, podiatry, and other office-based practices), AS/NZS 4187 (for hospitals and day surgeries), and AS/NZS 4815 (general office-based medical practices).

Look for an accuracy of around ±0.1–±0.5°C so you can demonstrate the load stayed within the required sterilisation tolerance. Pair this with traceable calibration to keep the data defensible at audit.

A validation kit typically bundles multiple temperature and pressure loggers with the software needed to program the loggers, download data, and generate audit-ready reports. Kits scale from a few loggers for a single autoclave up to larger multi-logger sets for fleet or chamber-mapping work.

Most quality systems require recalibration at least annually, and more often for critical applications. Pacific Sensor Technologies provides NATA-endorsed calibration, so your loggers remain traceable and audit-ready.

Yes. The same high-temperature loggers are widely used for steam steriliser validation, and complementary loggers cover dry-heat oven validation and washer-disinfector validation. Contact our team and we’ll match loggers to your specific process and temperature range.
