pH2Go

Introducing the new pH meter – pH2Go by Anton Paar

A portable device that fits seamlessly into your workflow

Fast pH testing shouldn’t feel like a fragile lab ritual. With pH2Go, Anton Paar brings digital pH measurement into the same modern, app-connected workflow you already know from the EasyDens and SmartRef – quick, reliable, and easy, whether you’re on the production floor, in the lab, or out in the field

Meet the pH2Go pH meter – fast, reliable pH measurement anywhere

pH2Go is Anton Paar’s first digital pH meter, designed for straightforward everyday measurements without the typical hassle that comes with traditional pH electrodes. Instead of relying on fragile glass, it uses a robust, glass-free solid-state ISFET sensor, which makes it easier to handle in routine work, simpler to clean after real samples, and more practical in production or field environments.

Even with very small sample volumes, pH2Go delivers quick, confident results, making it a good fit for fast checks during day-to-day quality control. Calibration is also kept simple through guided steps in the app, helping you maintain reliable measurements without slowing down your workflow. With connectivity to the mobile Meister Apps, your measurements transfer automatically and are saved digitally, so you can track values over time and keep documentation organized without manual data entry.
Built for real-world use, pH2Go is waterproof and designed to perform reliably outside of perfect lab conditions and can handle a wide range of liquid and viscous samples – from beverages and dairy products to sauces, honey, and industrial liquids.

One pH meter. Many applications. One digital workflow.

The pH2Go can be connected to all exciting Meister Apps (Brew-, Wine-, Proof-, Lab-, Coffee-, Pet Care-, and Reef Meister) and is suitable for diverse application areas.
Whether you’re fine-tuning a beverage process, managing a nutrient solution, or keeping water parameters stable, a quick pH check gives you immediate feedback on what’s happening right now.
Here is a quick overview of key application fields – and why pH is one of the most important values you can measure.

Beer Brewing

The pH strongly influences enzyme activity in the mash, impacting starch conversion and overall extraction efficiency. It also impacts yeast health, fermentation performance, and the final taste profile. With pH2Go, you can check pH quickly at critical steps – the app workflow can guide you through the process, helping you hit the right range for consistent quality batch after batch.

Wine making

From the moment grapes are harvested, pH plays a central role in microbial stability, taste balance, and color development. It also affects how well protective measures (like sulfite management) work and helps you steer fermentation more confidently. During and after fermentation – including malolactic fermentation – regular pH monitoring (Wine Meister app) supports stable, predictable results and a consistent house style.

Hydroponics

In hydroponic systems, pH directly controls nutrient availability. A small drift can lead to nutrient lockout, reduced growth, or plant stress – often before you see symptoms. Fast, frequent pH checks in reservoirs and feed lines help keep plants in their optimal uptake range. pH2Go’s quick measurement and tiny sample requirement make routine monitoring easy – especially when you’re managing multiple systems.

Water & wastewater analysis

pH value of water is a core parameter for process control, treatment efficiency, and compliance monitoring. It influences precipitation reactions, biological treatment performance, corrosion/scale risk, and disinfection effectiveness. Because sampling often happens in wet, harsh environments, a robust, waterproof (IP67) device that delivers quick results is a major practical advantage for field and plant use.

Dairy products

In dairy processing, milk pH measurement is a key indicator of product quality and safety, especially for fermented products like yoghurt and for cheese production, where pH influences texture, yield, and maturation behavior. Monitoring pH milk levels throughout heating, fermentation, and cooling steps supports consistent processing. Fast measurements and reliable documentation in the Lab Meister app help improve consistency and simplify quality records.

Aquariums

pH stability is critical for fish and plant health and can influence ammonia toxicity and the performance of biological filtration. Sudden pH changes can stress aquatic life even if other parameters look fine. While a fish aquarium water test kit can provide basic parameter checks, pH2Go enables quick, precise routine measurements without complicated handling – helping you maintain a stable environment and react early when values drift.

Pools

Pool pH affects swimmer comfort, the effectiveness of sanitizers, and the risk of corrosion or scale in equipment and surfaces. Keeping pH in the right range makes water treatment more efficient and helps protect your pool infrastructure. While teststrips pool methods often require visual color comparison and can be difficult to interpret accurately, pH2Go delivers fast, precise digital pH measurements in the Reef Meister app – allowing you to adjust dosing sooner and maintain stable water conditions.

Urine analysis

pH urine analysis is an important parameter for managing crystals and stones. Alkaline urine can promote struvite formation, while more acidic urine can be associated with calcium oxalate risk – so monitoring helps support early action and prevention. In cases like cystitis, keeping urine slightly more acidic can also help fight bacterial infection and reduce the risk of alkaline stone formation. With pH2Go and Pet Care Meister, results can be documented easily over time to support regular monitoring and vet-guided adjustments (diet, hydration, supplements).
