These Hanna meters have a two-operation button for all operations and settings. They have a waterproof casing rated IP67 and a tri-line display. They have automatic pH calibration, TDS factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4%. The HI-991301 has a higher range to meet exacting requirements for testing pH, electro-conductivity, total dissolved solids and temperature.
The meters include a HI-12883 multi-parameter probe. The probe has a domed-shaped pH bulb (0-13 pH), a single junction Ag/Cl reference electrode with a gelled electrolyte, a retractable cloth wick junction, a graphite EC/TDS cell, a solid-state pre-amplifier, and a temperature sensor.
