The Multi-parameter Analyzer is a portable, waterproof device designed for accurate field and laboratory measurements. It features a 3.5-inch LCD screen, supports USB communication, and can store up to 500 data sets per parameter. It measures pH, Ion, Conductivity, and Dissolved Oxygen (DO) with multi-point calibration and temperature compensation. Ideal for professional water quality testing, it includes automatic/manual modes, user-defined settings, and supports various measurement units and ion types.

pH
● 1-5 points calibration with Standard Recognition.
● Selectable pH buffer groups, including NIST, DIN, GB, USA.
● Automatic electrode diagnosis with pH slope and offset display.

Ion
