Table pH & Conductivity Bench Meter — Portable Water Quality Tester TDS/DO | Made in China — P911 P913 P914 P914_1

High-visibility 5-inch LCD: This table/bench meter is fitted with a high-resolution 5-inch LCD providing a wide 150° viewing angle and readable results from up to 5 meters for easy monitoring during tests. Intelligent microprocessor control: A built-in microprocessor chip delivers advanced functions including automatic calibration, ATC (Automatic Temperature Compensation), data storage, clock display, USB output and configurable function settings. Energy-saving safeguards include automatic power-off and a low voltage alarm. Connectivity and electrode support: Two USB interfaces enable PC data transfer and battery charging. A 3.5mm electrode interface provides a secure connection and the meter auto-recognizes different electrodes. Electrodes equipped with built-in chips can automatically store and recall their calibration data. Data logging: Stores up to 300 sets of readings along with date and time for convenient tracking and trend analysis. Measurement modes and specifications: The instrument supports pH and conductivity testing. In pH mode it automatically recognizes 15 buffers and supports both European & USA NIST standards as well as the Chinese Support 1 2, 3-point calibration method. Conductivity measurements use advanced algorithms with an accuracy range from 0.5S/cm to 200mS/cm and allow switching between conductivity, TDS, salinity and resistivity. The DO mode features ATC, manual salinity compensation and uses a polarographic DO electrode with short polarization time.
