HANNA HI991300 Portable pH/ EC/ TDS Meter

HANNA HI991300 Portable pH/ EC/ TDS Meter water quality meter measures pH, electro-conductivity, total dissolved solids, and temperature in a single instrument. To increase precision, you can select the meter which will work best with your range of conductivity from purified to brackish waters.

The Hanna Instruments HI 991300 and multiparameter water quality meter has only 2 buttons, yet you can select from a range of calibration buffers and even the temperature scale (°C or °F) most familiar to you. The housing is waterproof and rated for IP 67 conditions. The multi-parameter probe, the Hanna Instruments HI 1288, includes pH, EC / TDS, and temperature in one convenient, rugged handle.

Other user selectable features of the HI 991300 includes different TDS factors from 0.45 to 1.00 and a range of temperature coefficients (ß) from 0.0 to 2.4% for greater consistency and reproducibility. Also selectable are standardized buffer recognition values. To ensure against interference from transient electrical noise, a solid-state amplifier is integrated into the probe.
pH meters require regular calibration to perform at their optimal level. We strongly suggest purchasing calibration solutions.
