SUMMARY
Compact nitrate ion meter to measure nitrate ions by simply dropping a small amount (from 0.3mL) of sample directly
Reliable ion measurement by ion electrode method*. With its easy-to-use style and wide measurement range, it can be flexibly used in all aspects of nitrate ion measurement, including soil and crop flavor control.
LAQUAtwin NO3-11C (for crops), which includes a kit of the necessary items for measurement, such as pressing and soil preparation for crops.
LAQUAtwin NO3-11S (for soil) and the widely usable B-743 (for general use).
