About Thermo Scientific Orion Versa Star
The Thermo Scientific Versa Star benchtop meter with pH module and conductivity module can display pH, mV/RmV, conductivity, resistivity, salinity, and total dissolved solids (TDS) readings plus temperature on any of four customizable channels, with easy-to-use key layouts and color screen graphics on the large, backlit, fully customizable LCD display for advanced electrochemistry in the laboratory. The meter has four channels that can be configured by selecting from five available modules for pH, pH/ISE, conductivity, RDO/DO, and the pH/LogR module with advanced electrode diagnosis. All five modules measure temperature and can be mixed and matched as needed, with no need to power off the meter. Each channel can store 10 methods for customized procedures to differentiate between tests and/or users. Electrode status, time, date, sample ID, user ID, and calibration points are also displayed with the measurements. The pH module allows up to six points of pH calibration, with automatic recognition for USA/NIST and DIN (Deutsches Institut für Normung) buffers. The conductivity module offers conductivity, TDS, salinity, or resistivity capabilities. With the conductivity module, selectable reading reference temperatures of 5, 10, 15, 20, or 25 degrees C are available with linear, non-linear, nLFu or USP/EP curve. Practical salinity or natural sea water curves can be selected for salinity readings. TDS readings can be taken as linear or ISO/EN 27888 curves. The Versa Star meter has an IP 54 rating for limited ingress of dust and protection against water splashes. The electrode arm (included) can be attached to either side of the instrument. Meter and module inputs include Bayonet Neill-Concelman (BNC) and 8-Pin Mini-DIN. Meter output ports include two stirrer jacks, RS-232 for communications and data transfer, and two USB ports (one client, one host) for communication and data transfer. Certifications for this meter include CE, TÜV, and FCC Class A limits.

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. Thermo Fisher Scientific manufact
