Horiba B-751 LAQUAtwin Compact Calcium Ion Meter Part # 3200456570

Autocalibration function recognizes standards and is user-selectable for either one or two-point calibration. Measurement range 40ppm - 4000ppm. For submersible and special small sample or solid sample applications.

Temperature compensation

Only compact meter for a quick measurement of calcium 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.

*1 Smaller amount(0.05mL or more) can be measured with the sampling sheet B. (Please close the light shield cover. If a sample that contain particulate, please use ”Sampling sheet holder” (sold separately))
*2 When the measured value is out of the measurement range, the displayed value blinks. It should be used only as a guide.
*3 Selectable between one-point and two-point calibrations.
*4 Repeatability in measurement of a standard solution after calibration using the same standard solution.
*5 IP67?no failure when immersed in water at a depth of 1 meter for 30 minutes. But the product can not be used underwater.

The ion electrode may be subject to interference from other ionic species. The selectivity coefficient reflects the affinity between each ionic species and the electrode, and is used to correct for the influence of competing ions. Please see the Interfering ion influence ? pH range for further details.
