Hanna HI 991301 Waterproof pH/EC/TDS/Temperature Meter (High Range EC)
HANNA ® offers you a choice of 2 meters to meet your exacting requirements. HI 991300 and HI 991301 offer 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 ( °C or °F) 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 (ÃŸ) 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.
