B-721 LAQUAtwin Compact Salt Meter 3200456564
B-721 LAQUAtwin紧凑型盐度计3200456564
Horiba B-721 LAQUAtwin Compact Salt (NaCl) Meter Part No. 3200456564
Autocalibration function recognizes standards and is user-selectable for either two-point calibration (at 0.5% and 5.0%) or one-point calibration. Measurement range 0-25% sodium chlorid. For submersible and special small sample or solid sample applications.
Temperature compensation
Only compact meter to measure sodium ion to calculate into NaCl based 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 minimize 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

*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.
