VERSA STAR pH/ISE Module, VSTAR-ISE:

• Measures pH, concentration via ISE, mV, relative mV (RmV), or ORP alongside temperature.
• Supports up to six-point pH and ISE calibrations, allowing for corrections of individual points.
• Includes advanced ISE capabilities such as incremental techniques, timed end points, and selectable non-linear options for low concentration stability.

VERSA STAR Conductivity Module, VSTAR-CND:

• Determines conductivity, TDS, salinity, or resistivity with temperature measurements.
• Offers selectable reference temperatures for conductivity ranging from 5 to 25 °C including various curve options.
• Provides practical salinity or natural seawater curve selections for accurate readings.

VERSA STAR Dissolved Oxygen/RDO Module, VSTAR-RD:

• Measures dissolved oxygen as a percentage of saturation or concentration with temperature adjustments.
• Compatible with both Orion polarographic and RDO optical dissolved oxygen probes, featuring automatic probe type recognition.
• Calibration flexibility includes water-saturated air, air-saturated water, custom values via Winkler titration, or zero points.
• Automatic compensation for temperature and barometric pressure, with optional manual salinity correction included.
