| Repeatability | Concentration: ±3% or ±0.2 mg/L, whichever is greater for the readings (standard solution at 25℃) Temperature: ±0.3℃（equivalent input） |
| Temperature compensation | Compatible temperature element: platinum resistor: 1 kΩ (0℃) Temperature measurement range: 0℃ to 40℃ Temperature calibration function: 1 point calibration for comparison with the reference thermometer |
| Potassium ion concentration compensation | Compensation range: the potassium ion concentration is not more than 10 times the ammonium ion concentration and 1000 ppm or less. Compensation error: ±20%（reading） |
| Measurable pH range | pH 4.0 to 8.5 |
| Calibration | Reference solution calibration of the ammonia nitrogen (2points) Type of the reference solution: select 1 mg/L to 10 mg/L or 10 mg/L to 100 mg/L. Additional functions: automatic defect calibration judgment, calibration history |
| Adjustment | Sample adjustment using hand analysis (1 point, 2 points*１), standard curve input function (primary system) Additional functions: adjustment history (number of days elapsed from the previous adjustment, sample adjustment coefficient) |
| Abnormal detection | Calibration error, sensor diagnosis error, converter error |
| Sensor model | NO-2000: Nitrate nitrogen sensor |
| Sensor tip model | 7693: Nitrate ion tip, 7694: Chloride ion tip for compensation, 7211: Reference tip |
| Measurement range | Concentration: 0 mg/L to 1000 mg/L (display range: 0 mg/L to 2000 mg/L) Temperature: 0℃ to 40℃ (display range: -10℃ to 110℃） |
| Display resolution | Concentration: 0.01 mg/L: 0.00 mg/L to 10.00 mg/, 0.1 mg/L: 0.0 mg/L to 100.0 mg/L, 1 mg/L: 0 mg/L to 1000mg/L Temperature: 0.1℃ |
| Repeatability | Concentration: ±3% or ±0.2 mg/L, whichever is greater for the readings (standard solution at 25℃) Temperature: ±0.3℃（equivalent input） |
| Temperature compensation | Compatible temperature element: platinum resistor: 1 kΩ (0℃) Temperature measurement range: 0℃ to 40℃ Temperature calibration function: 1 point calibration for comparison with the reference thermometer |
| Chloride ion concentration compensation | Compensation range: when the chloride ion concentration is 100 times greater than the nitrate ion concentration, a correction factor must be applied to account for interference. Compensation error: ±20%（reading） |
| Measurable pH range | pH 2.0 to 12.0 When the pH is between pH 2.0 to pH 4.0 or pH 9.0 to pH 12.0, use sensor cap AM-CAP-PVC. Chloride ion tip can be used in the pH 2.0 to pH 8.0. However, when used at pH 2.0 to pH 4.0, the lifetime of the tip may be shortened. |
| Measurement inhibitors | Component: if the surfactant concentration is 10mg/L or higher, sensor performance may degrade, and measurement may not be possible. |
| Calibration | Reference solution calibration of the ammonia nitrogen (2points) Type of the reference solution: select 1 mg/L to 10 mg/L or 10 mg/L to 100 mg/L. Additional functions: automatic defect calibration judgment, calibration history |
| Adjustment | Sample adjustment using hand analysis (1 point, 2 points), standard curve input function (primary system) Additional functions: adjustment history (number of days elapsed from the previous adjustment, sample adjustment coefficient) |
| Abnormal detection | Calibration error, sensor diagnosis error, converter error |
