Additional information

We would like to inform you of an upcoming product update for the LAQUAtwin pocket meters.

To enhance product safety and prevent infants and young children from accidentally swallowing the batteries, HORIBA will be introducing a new battery cover on all LAQUAtwin pocket-sized analysers.

Overview of the product change

• Change: Battery cover for enhanced safety.
• Reason: To prevent accidental swallowing of batteries.
• Production date: from January 2026 in Japan
• Deliveries to EMEA distribution partners: from March 2026

As this change is currently being rolled out, mixed deliveries of the current and updated versions may occur during the transition phase.

Please note: The salt exchange sensors, both old and new, are not compatible with each other. Similarly, the conditioning solutions for the old and new versions are not compatible with the respective device variants.

How can you tell if you have an older or a new device?

If your Pocket Tester is marked ‘4-cell’, you have the latest version of this device. In this case, you will need the replacement sensors listed in the cross-selling section, as well as the standard and conditioning solutions. These have been specially optimised for the new Pocket Testers and are not suitable for older models.
