Bluelab pH PenPlus for Beer Brewing

The Bluelab pH PenPlus makes monitoring pH and temperature throughout the brewing process simple, reliable and convenient. Built with a replaceable pH/Temperature Probe and trusted Bluelab technology, it helps brewers minimise downtime, extend product life and make confident decisions at every stage of the brew.

Accurate pH measurement is an important part of brewing, from checking brewing liquor and mash pH through to monitoring wort and fermentation. The double-junction pH probe delivers reliable readings, while the replaceable probe design helps extend the working life of your meter. When the probe eventually reaches the end of its service life, the convenient screw-cap design makes replacement quick and easy, so you can get back to brewing without replacing the entire pen.

Built for the Brewing Environment

Designed with brewers in mind, the pH PenPlus features a bright backlit display, Hold Reading function and temperature readings in either °C or °F. Simple 2-point calibration, together with a 30-day calibration reminder, helps keep your measurements accurate and your brewing process on track.

Between uses, the KCl-filled silicone cap and internal sponge help maintain probe hydration, while the waterproof silicone probe cap and integrated lanyard provide convenient protection and handling in the brewery.

With an IP68 dustproof and waterproof rating, compact handheld design and automatic power-off function, the pH PenPlus is built to perform reliably in the demanding environment of home and commercial brewing.

Replaceable Probe – Keep Brewing, Not Replacing

The difference between the Bluelab pH Pen and pH PenPlus is simple: the pH PenPlus features a replaceable probe, helping minimise downtime and extend the life of your meter.

pH probes naturally wear over time, but with the pH PenPlus you don't need to replace the entire meter. Simply swap out the probe to restore performance and get back to brewing quickly.

Built to IP68 standards, the pH PenPlus is dustproof, waterproof and designed for demanding brewing environments. It's a practical tool for brewers who want reliable pH measurement without unnecessary disruption or replacement costs.

Keeping a replacement Bluelab pH ProbePlus on hand means less downtime, less disruption and continued confidence in your brewing measurements.

New Zealand-Made Quality

Bluelab products are designed and built for real-world use, not just the laboratory. That makes the pH PenPlus well suited to the knocks, splashes and spills that are part of everyday brewing.

The fully waterproof design provides added peace of mind when working around brewing equipment, liquids and wort. Whether you're checking mash pH, brewing water or wort, the pH PenPlus is built to handle the environment of the brewery.

Designed and built in New Zealand, Bluelab products are trusted by brewers around the world. The pH PenPlus is a practical, durable tool for brewers who want simple and reliable pH measurement.

To ensure the pH meter measures accurately the probe tip must be kept moist with KCl solution by adding 3-5 drops of KCl storage solution to the wetting seal of the storage cap each week.

For long term storage, remove the cap and place the pen upright in a plastic contianer. Cover the probe tip with KCl storage solution to ensure constant hydration. Check the containe regularly and top up the KCl storage solution as needed.

DO NOT let the probe tip dry. IF IT DRIES IT DIES!
