Description

The YSI 3100 conductivity meter provides high-accuracy measurements for basic conductivity. The instrument uses forced-current measurement technology. Other features include a direct-reading digital display, an adjustable temperature coefficient, reference temperature and automatic temperature compensation.

The YSI 3100 uses a line of NIST-traceable conductivity cells with built-in temperature sensors, assuring the most accurate measurements.

The YSI 3200 conductivity meter features user-selectable measurement modes. Measurement modes include conductivity, resistivity, salinity, total dissolved solids and temperature. Resistance Ratio Technology ™ provides unmatched accuracy for ultra-pure water measurements. The YSI 3200 has high and low alarms for process applications. The multipoint calibration feature allow for a variety of measurements to be taken with the same cell.

YSI 3100/3200 Series conductivity cells have built-in thermistors, allowing automatic temperature compensation. All YSI cells are calibrated according to OIML (International Organization of Legal Metrology) recommendations 56 (Standard solutions reproducing the conductivity of electrolytes) and 68 (Calibration method for conductivity cells).

YSI 3100/3200 Series conductivity cells are shipped with greater than 1% cell accuracy and include a certificate of traceability. The cells can be used as a secondary lab standard. They can also be re-calibrated (adjusted) to NIST traceable standards. The black platinum electrodes are extremely stable and linear.
