For instruments that are user calibrated at temperatures other than 25 °C, new firmware may be needed to support our new potassium acetate verification standards. See the following page for more information.

Update Instructions

Our AQUALAB instruments support firmware updates, allowing you to benefit from the latest features and bug fixes. To update the firmware on your device:

  1. Select your desired firmware version from the table below.
  2. Download the Firmware Updater Application.
  3. Connect your instrument to your computer using a USB or serial cable.
  4. Run the Firmware Updater Application and follow the on-screen instructions.
  5. After a firmware update, it is recommended that you run a water activity verification of your instrument.

Check Your Firmware Version

You can only update your instrument to a new firmware version if it has the same first number in its version (e.g. v2.#.# and v3.#.#)

To check which version your instrument is running:

  1. Navigate to the Config menu on your instrument.
  2. Scroll down to the About screen.
  3. Look for the Version number.
