5 Tips To Ensure Accurate Levelogger LTC Conductivity Calibration

Conductivity measurement devices have sensors that require calibration to ensure optimum performance. The frequency of calibration is largely dependent on the quality of the water it’s been exposed to during deployment. The conductivity sensor of an Levelogger LTC is highly accurate and sensitive, therefore requires regular calibration. Use our 5 tips to ensure an accurate and successful calibration every time.
