| Conductivity/TDS/°C/NaCl Meter |
| Model HI9835 |
The HI 9835 combines the more important parameters you need for measuring conductivity. Now you can sample Electro-Conductivity (EC), Total Dissolved Solids (TDS), sodium chloride (NaCl) and temperature all at once. Hanna's probe design innovation uses 4 rings enhanced with platinum for greater stability while increasing the range of measurable concentrations and temperature. You can choose between automatic and manual temperature compensation to facilitate your operating requirements. In addition, you can also select from a range of TDS factors from 0.40 to 0.80 and a range of temperature coefficients 0.00 to 6.00% for greater consistency and reproducibility. The housing is completely waterproof and built to survive the harsh conditions of field use. For extended time studies, this meter can be connected to the available 12 VDC power supply. |
