Multi-Parameter Handheld Water Tester for pH, EC, TDS, Salinity, DO, and Temperature
The AZ 86031 Portable Combo Water Quality Meter is a rugged, IP67-rated, multi-functional handheld meter designed for real-time monitoring of pH, electrical conductivity (EC), total dissolved solids (TDS), salinity, dissolved oxygen (DO), and temperature. Compatible with replaceable probes, this instrument is ideal for aquaculture, water treatment, marine applications, and laboratory or field-based environmental testing.
The meter automatically detects the connected probe and adjusts its display accordingly. Its large dual LCD, auto temperature compensation (ATC), multi-point calibration, and memory recall function make it a reliable and user-friendly choice for water quality professionals who require versatility, precision, and portability in a single device.
