Description
The HI-2020 Edge® measures pH, conductivity, and dissolved oxygen through its digital electrodes. These digital electrodes are auto-recognised, providing sensor type, calibration data and a serial number when connected to edge® (with plug-in 3.5mm connector).
The electrode holder features a swivel, adjustable arm with built-in cradle to hold edge pH meter securely in place at optimum viewing angle.
Supplied with bench-top stand; electrode holder; bracket for wall-mount; USB cable; power adaptor; instruction manual.
edge® pH kit: HI-11310 digital pH electrode with integrated temperature sensor; sachets of pH 4.01, 7.01, 10.01 buffer solutions; sachet of electrode cleaning solution.
Optional accessories include:
edge® DO kit: HI-764080 dissolved oxygen electrode, HI7041S refill electrolyte solution, DO membrane caps, o-rings.
edge® EC kit: HI-763100 conductivity probe; 1413, 12880, 5000 µS/cm conductivity standard sachets; electrode rinse solution sachets.
