HORIBA B-741/ 742/ 743

Only compact meter for a quick measurement of nitrate ion using ion selective membrane.Flat sensor technology and 60 years of sensor engineering realizes a reliable and direct measurement of a drop of the sample from 0.3mL. Use sampling sheet ( sold separately) to measure down to 0.05mL or more.Unique sensor mechanism realizes direct measurement of solid, viscous, powder samples. No need for a beaker to calibrate or measure. Just drop the standards and sample on the flat sensor, saves you time and minimize wasting your precious sample.This lightweight, pocket-sized meter is suitable for research and industrial applications in diverse fields. 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
