Main Features The measurement process simply involves placing the sample on the meter's flat sensor, Accurate measurements can be taken from samples ... moreas small as 0.3mL, Automatic range switching gives a wide display range and facilitates highly precise measurements, The meter employs a highly selective flat ion electrode that ignores other ions Ultrathin and lightweight. The meter can be easily carried to any location for on-site testing, With the Horiba Sodium Ion Meter. Sodium concentration is as simple as placing a tiny sample on the meter's flat sensor. Accurate measurements can be taken from a sample as small as 0.3mL. The Model B-722 sodium meter is capable of making accurate measurements of sodium ion concentration from a very small sample size. This meter employs a selective sodium ion electrode that is unaffected by pH and the presence of other ions, enabling the accurate measurement of sodium ion concentrations. The meter's microprocessor converts this information to give a measurement of sodium concentration(Na+) Auto calibration function recognizes standards and is user-selectable for either one- or two-point calibrations.
