HANNA HI8731 Portable Conductivity/TDS Meter with Probe, Conductivity Range: 0 to 6000 Microsiemens/cm, Temperature Range: 0 to 70°C, TDS Range: 0 to 3000ppm

HI 8731 is a complete, versatile and water-tight conductivity meter, that can measure EC and TDS with extended ranges (from 0 to 6000 µS/cm range and from 0 to 3000 ppm, respectively), and temperature from 0 to 70°C. The desired measurement mode is easily selectable through a membrane keyboard on the front panel. Conductivity measurements are automatically compensated for temperature changes with a fixed coefficient of 2%/°C. The HI 761285 probe features a built-in temperature sensor, and it has been designed to require little maintenance. The meter can be calibrated at one point for EC or TDS, while the temperature range is factory calibrated.
