This Thermo Scientific Orion Star A322 Conductivity Portable Meter kit is the top choice for testing samples anywhere. It is rugged and dependable, making it ideal for every sample, every day, everywhere. Kit includes the 013010MD DuraProbe Epoxy 4-Cell Conductivity Cell (Cell constant, 0.475 cm-1; 8-pin Mini-DIN connector; 10 ft. cable; for use with Star and Star Plus meters) which is designed for the highest accuracy under demanding field and plant conditions. This design compensates for electrode fouling, cable and connector resistance, and polarization errors. It has a rugged epoxy body, graphite sensors, and is temperature compensated. Kit also includes the 01100710 Conductivity 1413uS/cm Standard Pouches (692ppm as NaCl TDS Standard, 10 x 15mL Pouches) and the 911110 Rinse Solution Pouches (10 Individual Use Pouches) and comes with the STARA-CS Star A portable meter hard carrying case and the STARA-AR Star A portable meter armor with stand and electrode holders. The meter features a large, backlit graphic LCD display. The informative display shows conductivity, TDS, salinity, resistivity, and temperature along with electrode status, time, date, sample ID, user ID and calibration points. Advanced features such as stability and averaging options provide additional options allowing for laboratory accuracy everywhere you need it. It provides ease of use with its plain language screen prompts, soft keys that update for easy selection, and a multi-language interface that supports English, Spanish, French, Italian, German, and Chinese. The AUTO-READ™ feature locks in the stable reading on your screen. The ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals. Selectable cell constant allows for use with 2- or 4-cell conductivity cells. For advanced accuracy, selectable reading reference temperatures of 5°, 10°, 15°, 20° or 25°C with linear, non-linear, nLFu or EP curve options. Choice of practical salinity or natural sea water curves for salinity readings. Linear or ISO/EN 27888 curves for TDS. The non-volatile memory holds up to 5000 data points with time and date stamp. Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software.
