PH30E Benchtop pH Meter: GLP, USB & RS-232, Multiple Buffers

Metalsin‘s PH30E pH meter represents the flagship of our benchtop series, offering an advanced analytical platform for laboratories that demand high-volume data handling and global standard compliance. It is the premier choice for professional monitoring in potable water, raw water, wastewater, and reclaimed water systems. It is a powerhouse of precision, designed to bridge the gap between complex industrial requirements and laboratory efficiency. It provides an elite level of traceability and versatility for water quality professionals worldwide.

High-Performance Features

• GLP-Compliant Data Management (500 Data Sets): The PH30E benchtop pH meter is built for regulated environments, featuring an expansive internal memory that stores up to 500 data sets. This system is fully GLP-compliant (Good Laboratory Practice), ensuring that every measurement is timestamped and traceable. This is critical for municipal water facilities and industrial plants that must undergo rigorous environmental audits or quality certifications.
• Seamless USB and RS-232 Communication: To support modern digital workflows, the PH30E is equipped with both USB and RS-232 communication ports. This dual-connectivity allows for effortless data transfer to a PC for analysis or direct integration with laboratory printers and LIMS (Laboratory Information Management Systems). It transforms your pH meter from a standalone tool into an integrated node in your data infrastructure.
• Global Standard Calibration & Recognition: The PH30E offers unparalleled flexibility with configurable pH buffer calibration, supporting pre-set groups for NIST, DIN, GB, USA, and GOST standards. Whether your facility operates under American (USA), European (DIN), or Asian (GB/NIST) protocols, the PH30E automatically recognizes the specific buffer values for these global standards. This “plug-and-play” calibration ensures that your results are internationally consistent and valid, regardless of which chemical standard your supply chain provides.

Intelligent Design and Rugged Reliability

The PH30E benchtop pH meter for waterworks lab use: GLP-compliant, USB & RS-232 communication, multiple global standard buffers.

Beyond its advanced data features, the PH30E benchtop pH meter is designed for maximum operational ease and longevity. It features a massive 7.0-inch high-resolution LCD display for superior data visualization. Users can choose from Auto-read, Timed-read, and Continuous-read modes to fit different sampling protocols, while the Auto-hold feature ensures endpoint stability. The device supports a comprehensive 1-5 points calibration and provides Automatic Electrode Diagnosis, displaying the pH slope and offset to monitor electrode health in real-time. Wrapped in an IP54-rated waterproof housing, the PH30E also includes a Reset feature for quick troubleshooting and Automatic/Manual Temperature Compensation to ensure precision in any thermal environment.
