Page 5: Section 1 Product Overview
Section 1 Product overview The Intellical ISENO3181 series probes are digital, combination ion-selective electrodes (ISE) that measure the concentration of nitrate in general water samples. The probes have a built-in temperature sensor, a non-refillable gel reference and non-replaceable membranes. Refer to... -

Section 6 Sample measurement The procedure that follows is applicable to meters that can connect to Intellical ISE probes. Refer to the applicable meter documentation for meter operation and probe-specific settings. 6.1 Sample measurement notes Read the notes that follow before sample measurements. •... -
Page 10: Low-Level Measurements
6.3 Low-level measurements – Use the guidelines that follow for measurements at low concentrations (<1 mg/L NO –N). • Fully rinse the probe with deionized water and blot dry between measurements. • Soak the probe in the lowest concentration standard solution for 1 hour maximum before calibration and measurement. -
Page 11: Section 7 Verify The Calibration
Section 7 Verify the calibration Measure the value of a fresh standard solution at regular intervals to make sure the result is accurate. The meter compares the expected standard solution value to the measured value and accepts or rejects the measurement. The user can change the standard solution and acceptance criteria for verification in the probe-specific settings. -
Page 12: Section 8 Maintenance
Section 8 Maintenance Regular maintenance is necessary for the best accuracy, stabilization time and life of the probe. Fully rinse the probe with deionized water between measurements to keep the probe clean. 8.1 Clean the probe Rinse the probe with deionized water regularly to remove mineral or sample buildup on the sensing element. -
