Orion® 4-Star Bench-Top pH/Conductivity Meter
• Dual channel, dual display, three-button function
• Reliable measurements
The dual-channel Orion® 4-Star is easy to use and provides extremely reliable measurements. It provides accurate conductivity, resistivity, salinity, TDS and temperature measurements for soil and water analysis.
The meter accepts both four- and two-electrode cells and offers a wide range of GLP-related features (including an available 21 CFR Part 11 software option). The optional one- to five-point calibration for both conductivity and pH ensures accuracy even at extreme levels of concentration. The Smart Stability™ and Smart Averaging™ functions help to simplify the measuring process. The Orion® 4-Star is capable of storing up to 10 setup parameters and calibrations (which makes it ideal for use by several users) and other methods and software can also be easily downloaded. Utilizes BNC pH electrode connectors, and has automatic or manual pH calibration. The Orion® 4-Star features Auto-Buffer Recognition of DIN and NIST/US buffers, automatic or manual temperature compensation, and a 200-point data logger which can be downloaded to a computer via an RS232 or USB interface (sold separately). Rugged dust-proof and splash-proof design. CE, CSA, UL and FCC Class A limits approved. The Orion® 4-Star Kit includes a pH meter, a Triode™ pH/ATC electrode, a conductivity cell with 1.5m cable, a conductivity/TDS standard (1413µS/cm, 5 x 60mL), 475mL each of pH 4.01, pH 7.00 and pH 10.01 buffer, pH electrode storage solution and an electrode stand.
