The AZ Instrument 84051 is a high-performance, multi-parameter combo water tester designed for meticulous diagnostics of pH, Conductivity, TDS, Salinity, Dissolved Oxygen (D.O.), and Temperature. This all-in-one instrument stands as the definitive professional standard for aquaculture, environmental research, and water treatment facilities. Its smart interface automatically recognizes the connected probe type and switches the display to the relevant parameter, offering unparalleled flexibility in the field.
Engineered for rigorous professional use, the 84051 features interchangeable probes equipped with anti-collision caps to prevent damage from particles in the water. It supports Multi-point Calibration (up to 3 points for pH and 4 for EC) and features Automatic Temperature Compensation (ATC) for stable readings in varying conditions. With a 99-point internal memory, manual altitude/salinity compensation for D.O. testing, and a bright green backlight for low-light environments, the AZ Instrument 84051 provides a laboratory-grade analysis experience in a portable, rugged format.
