Product Description
Conductivity and TDS checks in the field call for a meter that is light, tough and quick to calibrate. The OHAUS Starter 300C portable conductivity meter delivers reliable readings in a compact handheld design.
This listing is for OHAUS item number 30219115: Starter 300C Portable Conductivity Meter ST300C-G, with STCON3 Electrode, 0.01 µS/cm-199.9 mS/cm. It measures 0.01 µS/cm to 199.9 mS/cm with ±0.5% accuracy, TDS from 0.1 mg/L to 199.9 g/L and 0 to 100 °C. Automatic temperature compensation with an adjustable coefficient and 1-point calibration keep setup simple. The ABS housing includes a wrist strap and runs about 250 hours on four AAA batteries; the ST300C and ST300C-G include an STCON3 electrode, and the ST300C-B is meter only. LIGHT LABS supplies the OHAUS line with knowledgeable support from our Englewood, Colorado team.
