Design Features

• Intelligent Auto-Hold Technology: The PH20E features an advanced Auto-hold function that intelligently senses and locks the measurement endpoint. In complex samples like wastewater or raw intake water, pH readings can take time to stabilize. Instead of the operator guessing when to record a value, the PH20E automatically detects when the electrochemical signal is stable and “freezes” the result. This eliminates human error, ensures consistency between different technicians, and guarantees that every data point is captured at the optimal moment of stability.
• Comprehensive Data Management: Efficiency is built into the core of the PH20E with a robust data storage capacity of 50 sets for each parameter. Manual logging is time-consuming and prone to transcription errors. With the ability to store 50 distinct data sets per parameter, users can perform high-volume testing—such as monitoring multiple stages of a reclaimed water system or performing hourly checks on potable water—and review the historical data later. This facilitates easier trend analysis and simplifies the reporting process for environmental compliance.
• Versatile Performance & Industrial Build: Beyond its smart sensing, the PH20E benchtop pH meter is packed with features to streamline your workflow. It boasts a 6.0-inch high-resolution LCD screen for crystal-clear visibility and offers multi-reading modes, including auto-read and continuous-read for real-time monitoring. The device supports 1-3 points calibration with automatic recognition of NIST buffers (pH 1.68, 4.01, 7.00, and 10.01), while also allowing manual calibration for custom standard solutions. To ensure accuracy across fluctuating temperatures, it includes both Automatic and Manual Temperature Compensation. Built for durability, the unit is IP54 waterproof and dustproof, protecting your investment in demanding plant environments. Should settings ever need a refresh, the Reset feature instantly restores the device to factory defaults, ensuring peak performance at all times.
