Product Description This equipment contains button batteries and is not intended for general consumer use. (i) the equipment is intended to be used in trades, professions or industries only; (ii) the equipment is not intended for sale to the general public; (iii) the equipment is not intended to be used where children are present; The only compact meter to measure sodium ion concentration and calculate into salinity or NaCl salt concentration unlike the conductivity converted meters. Flat sensor technology and 60 years of sensor engineering realizes a reliable and direct measurement of a drop of the sample from 0.3mL.Unique sensor mechanism realizes direct measurement of solid, viscous, powder samples. Use sampling sheet (sold separately) to measure down to 0.05mL. No need for a beaker to calibrate or measure. Just drop the standards and sample on the flat sensor, saves you time and minimizes wasting your precious sample. Applications include: Soil and sap testing for improved agriculture; food testing* * Detection of ions in water only; electrolytes in oils cannot be measured. Ion measurement can be affected by non-target ions. Functions Autocalibration function recognizes standards and is user-selectable for either one- or two-point calibrations. Auto range change Temperature compensation IP67 waterproof Auto hold Automatic power off （30 minutes）
