Digital pH Meter:
pH2Go

Lab-grade accuracy, pocket-sized format

With an accuracy of ±0.02 pH across the full 0.00 pH to 14.00 pH range, pH2Go is ideal for consistent, traceable measurements in everyday use, production, and field work. The sample well requires only 0.5 mL, conserving precious material and enabling quick rinse-and-repeat workflows between samples. Stable readings are delivered in just two seconds, and automatic temperature compensation during calibration ensures high precision under changing conditions. Users can choose between multiple measurement modes – including quick, continuous, and interval – making the device equally suited for fast routine checks as well as in-depth monitoring of sample behavior over time.

Built for any environment – waterproof and glass-free design

The pH2Go digital pH meter features a robust ISFET pH sensor and a gel-based reference electrolyte with a non-depleting reservoir to ensure long-term stability. Free from fragile glass, it eliminates any risk of contamination from shards, making it ideal for food and beverage analysis. The rugged and waterproof housing with an IP67 rating enables safe handling indoors and outdoors – even under demanding conditions – while the smooth, easy-to-clean sample well rinses in seconds and tolerates dry storage without damage. Battery-powered operation with long runtime supports truly portable pH control wherever it is needed.

Smart app guidance, calibration, and data visualization

The free iOS and Android app guides each calibration and automatically sets the appropriate calibration scheme based on the planned measurements. Users can perform up to a 5-point calibration with predefined DIN, NIST, or JIS buffer groups, as well as add custom buffer sets. All measurements and calibrations are automatically logged, ensuring a complete, traceable history. Results are displayed in clear visuals and explanations to provide context and application-specific insights.
