The HI-991300 meter features two operation button and is simple to use. All operations and settings, including calibration buffers and temperature scale selections, are made through these two buttons. It has a waterproof and compact casing rated for IP67 conditions and a large tri-line display. The meter has automatic pH calibration at one or two points and a single conductivity calibration. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4% for better conductivity or TDS solution temperature compensation. The meter is supplied with a multi-parameter probe specifically designed for this meter.
