New Zealand-made quality
The Bluelab products are designed and built for the home user - not the lab - so you can relax knowing that your pen can withstand the knocks, drops and deep-water plunges that come with everyday brewing. In fact, the fully waterproof Bluelab pH Pen is designed to float when it lands in your beer.
The Bluelab pH Pen was designed and built in New Zealand. Tried and trusted by brewers all over the world, this essential tool is one of our top-selling products.
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!
