Table pH & Conductivity Meter — Portable/Bench TDS Water Quality Tester P911 P913 P914 (P913_1)

Professional portable/bench water quality meter compatible with models P911, P913 and P914 (P913_1). Built around a high-resolution 5-inch LCD, the instrument offers a wide 150° viewing angle and readable output from up to 5 meters for convenient monitoring. A built-in microprocessor delivers intelligent control: automatic calibration, ATC (Automatic Temperature Compensation), configurable function settings, USB output, clock display, plus energy-saving features such as automatic power-off and a low voltage alarm. Connectivity includes two USB interfaces for PC data transfer and battery charging, while a 3.5mm electrode socket provides a secure link to probes. The meter auto-recognizes different electrodes, and probes with integrated chips can automatically save and recall their calibration data. Memory capacity holds up to 300 sets of records, each stored with reading, date and time for trend analysis. Measurement modes cover pH and conductivity testing: pH mode supports automatic recognition of 15 buffers and complies with European & USA NIST standards as well as the Chinese Support 1 2, 3-point calibration method. Conductivity mode measures accurately across the 0.5S/cm to 200mS/cm range and can display conductivity, TDS, salinity and resistivity. The DO mode includes ATC, manual salinity compensation and uses a polarographic DO electrode designed for short polarization time.
