Introducing the only compact meter designed for rapid measurement of nitrate ion and nitrate-nitrogen concentrations, utilizing ion-selective membrane technology. With flat sensor technology refined over 60 years of sensor engineering, it enables dependable and direct measurements from just a drop of sample, starting from 0.3 mL. Utilize a sampling sheet (available separately) to extend measurements down to 0.05 mL or more. Its unique sensor mechanism facilitates direct measurements of solid, viscous, and powder samples, eliminating the need for a beaker during calibration or measurement. Simply drop the standards and sample onto the flat sensor, saving time and minimizing sample wastage. This lightweight, pocket-sized meter finds utility in research and industrial applications across diverse fields.
Key Applications:
- Soil and sap testing for enhanced agriculture
- Food testing (Note: Only detects ions in water; cannot measure electrolytes in oils. Ion measurement may be affected by non-target ions.)
Key Functions:
- Autocalibration function capable of recognizing standards, with user-selectable options for one- or two-point calibrations
- Automatic range change feature
- Temperature compensation functionality
- IP67 waterproof rating for durability and reliability
- Auto hold function for ease of use
- Automatic power-off after 30 minutes to conserve battery life
