The 5501 is a benchtop multi-parameter meter measuring pH, ORP, conductivity, TDS, and temperature in one instrument. Auto buffer recognition for pH, auto/manual temperature compensation, one-touch parameter switching — designed for laboratory and QC use.
Five parameters: pH (0–14, 0.01 resolution), ORP in mV, conductivity (0.1 μS to 199.9 mS), TDS in ppm, and temperature. All from a single instrument with one-touch switching.
5500 is an online panel-mounted conductivity/TDS indicator only. 5501 is a benchtop instrument measuring pH, ORP, conductivity, TDS, and temperature. Choose 5500 for continuous panel monitoring; 5501 for laboratory multi-parameter testing.
Automatically identifies the standard buffer solution (pH 4, 7, or 10) during calibration — eliminating manual entry, reducing errors, and speeding up two-point pH calibration.
Water quality labs, pharmaceutical QC, food and beverage testing, environmental testing, educational institutions, and swimming pool testing — any setting needing multi-parameter water quality analysis.
