Halo2 features
Designed for dough
This version of the Halo2 pH tester is specifically designed to measure dough and bread effectively. A tapered conical electrode tip allows the end of the tester to easily be immersed in semi-solids like dough and is also sturdy enough to insert into baked bread to take an accurate pH reading. In comparison to other pH testers, this specific design enables accurate measurements below the surface of the bake for the best results.
Automatic temperature compensation
Built-in automatic temperature compensation allows bread and dough to be measured at any point during breadmaking, proofing and following baking. A comprehensive temperature range from 0.0 to 60.0°C ensures the readings from Halo2 are accurate regardless of the stage where the bread or dough is measured.
Safe for food
Thie Halo2 bread tester is made from food-grade PVDF, a material that is easy to clean and disinfect. PVDF has resistance to chemicals, fungal growth and ultraviolet light, making it a suitable material for both at-home and commercial breadmaking. This tester helps businesses and home bakers comply with HACCP standards for food safety.
Fast, stable readings
The HI-9810382 Halo2 tester has a double junction design in its built-in electrode, where a silver-free electrolyte solution interacts with the sample. This specific design helps to prevent clogging and provides a fast response when testing, with highly stable readings you can trust when measuring bread and dough.
Connect via Bluetooth
Halo2 testers are equipped with Bluetooth Smart Technology, allowing all measurements to be stored and accessed directly through the Hanna Lab app. This app is available for iOS and Android, providing easy access to previous results and allowing you to keep track of pH measurements throughout the baking process. Stability tagging sends tagged results to the Hanna Lab App only after measurement stability has been achieved.
Single-button operation
All operations for the Halo2 are completed using a single button. Press the button to turn Halo2 on, then press again to tag your sample during measurement. The simple design of Halo2 makes it quick and easy to take measurements, with calibration also easily accessible through the single-button interface with Hanna calibration sachets.
Long battery life
The Halo2 series is powered by a CR2032 lithium-ion coin-style battery, providing up to 1,000 hours of usage before replacement is required. This battery is easily removed and replaced, allowing for seamless continued operation.

FAQs
When can the Halo2 bread tester be used for baking?
The Halo2 tester for bread and dough can be used at any point in the breadmaking process, including proofing and after baking. This versatile tester includes temperature compensation for measurement, enabling it to be used at all stages in the process.
Why should I measure the pH in my dough?
The pH of your dough when proofing can have an impact on the taste of your bread. pH affects yeast activity during fermentation. An optimal, balanced pH helps to achieve the desired taste, preventing under-rising and unexpected textures. In addition, low pH in bread such as sourdough inhibits the growth of bacteria and mould, keeping bread fresh for longer. Monitoring pH allows you to make any necessary changes to achieve the perfect loaf every time.
How do you use Halo2 testers?
Halo2 testers feature single-button operation, allowing for fast and convenient measurement by turning on the tester and taking a reading. Connect the Halo2 to your phone or tablet via the Hanna Lab app to easily access and store data from testing. Halo2 functions as both a standalone and Bluetooth-connected pH tester, allowing you to choose the option that best suits your requirements.
How do you clean Halo2 testers?
Using a suitable cleaning solution is the ideal way to clean Halo2 testers. Hanna Instruments stocks cleaning solution sachets for specific applications, such as the HI-700684p Electrode Cleaning Solution for Bread and Dough. Cleaning your electrode between tests is essential for measurement accuracy.
