Convenient conductivity, TDS, salinity, and temperature field measurements.

Field Conductivity Meters Product Description

The EC300A field conductivity meters are part of the EcoSense family of products. These simple and affordable field conductivity meters are precision tools that measure conductivity, salinity, total dissolved solids, and temperature. The model EC300A field conductivity meter comes with a super-stable rugged weighted four-electrode conductivity cell assembly on several different cable lengths. The field conductivity meters have a built-in microprocessor which calculates and compensates for all parameters related to conductivity and temperature determinations. The field conductivity meters are waterproof (IP67) when the connector cap is installed. The mechanical touch keys of the field conductivity meters are highly reliable with tactile and audio feedback. The field conductivity meters use one 9V battery which provides up to 500 hours of battery life. The field conductivity meters offer a low battery indicator and an automatic shutoff feature to help you maintain your instrument. Re-calibration is not required when power is restored to the field conductivity meter. The front of the field conductivity meters have a large LCD that displays temperature and either temperature compensated or non-temperature compensated conductivity, salinity or TDS simultaneously along with user prompts and mode indicators. The field conductivity meter prompts users through calibration and measurement procedures. Other field conductivity meter features include automatic conductivity ranging, can store 50 data sets in memory, and 50/60 Hz AC noise rejection. This field conductivity meter is universal and user-friendly for field, industrial and laboratory applications. This line of field conductivity meters comes with a one year instrument, electrode, and cable warranty.
