Yes, the EC and TDS reading can have a temperature coefficient ß selectable from 0 to 10%/°C.
The instrument supports four different EC working ranges from 0 to 199.9 μS up to 0 to 199.9 mS, and four TDS ranges from 0 to 100.0 ppm to 0 to 100.0 ppt for HI 710 models.
The device requires a 230 ±10% Vac or 115 ±10% Vac, 50/60 Hz power supply.
