The Orion Star™ A212 Conductivity Meter features selectable cell constant enabling use with two or four conductivity cells along with selectable reading reference temperatures of 5, 10, 15, 20 or 25° with linear, nonlinear, nLFu or EP curve options all for the purpose of gathering accurate results. Linear or ISO/EN 27888 curves for TDS and a choice of practical salinity or natural sea water curves for salinity readings.
There are many other additional features which make the Thermo Scientific™ Orion Star™ A212 Conductivity Meter the perfect choice for taking simple readings and these are:
