Hanna Instruments® HI 98194 pH/ORP/EC/DO Multiparameter Waterproof Meter
Hanna Instruments Model HI 98194 Multiparameter Waterproof Meter
The HI 98194 meter measures pH, ORP, EC, TDS, resistivity, salinity, seawater sigma, dissolved oxygen, atmospheric pressure, and temperature. This waterproof meter delivers reliable measurements and features a rugged IP67 waterproof enclosure. The meter includes a digital probe that is equipped with a built-in temperature sensor. Ports on the probe accommodate color-coded, field-replaceable sensors. In addition to auto-sensor recognition, the meter features automatic temperature compensation, automatic logging for up to 45,000 samples, and log-on-demand to store data at the press of a button. Logged data can be transferred to a PC using the included micro USB cable and software. GLP data from the previous five calibrations helps to ensure that Good Laboratory Practices are met. A dedicated Help key provides context-specific assistance on the backlit display. Includes probe with 4m cable, pH/ORP sensor, EC sensor, DO sensor, probe maintenance kit, calibration beaker, quick calibration solution, PC software, micro USB cable, batteries.
