The Thermo Scientific VSTAR-PH module can be placed in any of four channels of the Orion Versa Star benchtop meter to display pH, mV/RmV, ISE (ion selective electrode), and temperature for advanced electrochemistry in the laboratory. The pH/ISE module provides up to five point pH calibration with automatic recognition of USA/NIST and DIN (Deutsches Institut für Normung) buffers. Advanced ISE measurement features include auto-blank, timed end point, linear point-to-point, non-linear selectable auto-blank, low-concentration range stability, ISE ID, and incremental techniques. Calibration errors can be edited without a complete recalibration.

|mV/RmV range (pH/ISE module)||+ or – 2,000.0mV|
|mV/RmV range (pH/ISE module)||+ or – 0.2mV or + or – 0.05% of reading, whichever is greater|
|ISE range (pH/ISE module)||0 to 19,999|
|ISE relative accuracy (pH/ISE module)||+ or – 0.2mV or + or – 0.05% of reading, whichever is greater|
|Temperature range (pH/ISE module)||-5 to 105 degrees C/23 to 221 degrees F|
|Temperature relative accuracy (pH/ISE module)||+ or – 0.1|
A multiparameter meter is a benchtop or handheld device that can take multiple readings on a single sample. It measures parameters such as the pH level (acidity or alkalinity of a substance), conductivity (the amount of salts or other compounds present in water), dissolved oxygen (DO, the amount of oxygen in a liquid), temperature, total dissolved solids (TDS, anything present in water other than the pure water molecule and suspended solids), salinity, resistivity, and oxidation reduction potential (ORP). Applications for multiparameter meters include water testing, pharmaceuticals, agriculture, winemaking, water-treatment plants, and acquaculture. Devices with a benchtop body are often used for indoor laboratory use or in a manufacturing setting; handheld, portable devices are typically used for fieldwork. Sensors are used with a meter to measure the parameters of a substance.
