Hanna Instruments HI 98191 Professional pH or ORP or ISE Waterproof Meter

This versatile meter measures pH and temperature using the included titanium probe, or you can switch probes to obtain mV readings using an ORP probe (sold separately). In addition, the meter is pre-programmed with data for 17 standard ISEs for use when a specific ISE electrode (not included) is attached to the meter. The meter offers up to five-point pH calibration with seven standard pH buffers and five custom pH buffers available. CAL Check™ alerts you of problems during calibration, and GLP data from the previous calibration ensures that Good Laboratory Practices are met. The meter’s log-on-demand function stores up to 300 samples which can later be transferred to a PC using the included USB cable and software. This IP67 waterproof meter features a backlit screen and an AutoHold function to automatically hold the first stable reading on the display. Includes combined pH/temperature electrode, temperature probe, pH 4.01 and 7.01 buffer solutions, cleaning solution, two 100 mL plastic beakers, batteries, PC software, micro USB cable, instruction manual, and carrying case.
