pH-Conductivity-TDS Meter

Hanna Instruments HI 991300

The Hanna HI 991300 offers you the combination of pH, electro-conductivity, total dissolved solids and temperature. To increase precision, you can select the meter which will work best with your range of conductivity, from purified to brackish waters. There are only 2 buttons, yet you can select from a range of calibration buffers and even the temperature scale (øC or øF) most familiar to you. The housing is waterproof and rated for IP 67 conditions. The multi-parameter probe, HI 1288, includes pH, EC/TDS and temperature in one convenient, rugged handle. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients (á) 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. Range pH 0.00 to 14.00 pH Range EC 0 to 3999 æS/cm Range TDS 0 to 2000 ppm (mg/L) Range Temperature 0.0 to 60.0øC (32.0 to 140.0øF) Resolution pH 0.01 pH Resolution EC 1 æS/cm Resolution TDS 1 ppm Resolution Temperature 0.1øC (0.1øF) TDS Conversion Factor selectable 0.45 to 1.00 with 0.01 increments (default 0.50) pH Calibration automatic at 1 or 2 points with 2 sets of memorized standard (pH 4.01/7.01/10.01 or 4.01/6.86/9.18)
