| Product name | Industrial 2-channel specific resistance meter | |||||
|---|---|---|---|---|---|---|
| Model | HE-960RW | |||||
| Measurement method | Electrode type (2-electrode method) | |||||
| Sensor input | 2 channels (for concurrent measurement with sensors isolated each other) | |||||
| Cell constant | 0.01/cm | |||||
| Temperature sensor specifications | Platinum resistance 1000 Ω/0℃ | |||||
| Measuring range | Measurement unit | kΩ•m | 0 to 20.0 | 0 to 200.0 | 0 to 1000 * | |
| MΩ•cm | 0 to 2.00 | 0 to 20.00 | 0 to 100.0 * | |||
| *: Measurable without temperature compensation | ||||||
| Temperature | 0℃ to 100℃ (The number of digits after the decimal point is selectable from one and two. The range of measurements is −20℃ to 120℃.) | |||||
| Desalination rate | 0% to 100% | |||||
| Temperature: 0℃ to 100℃ (Select your desired decimal point from 0, 1, and 2 digits.) | ||||||
| Repeatability | Within ±0.1% of the full scale (in equivalent input) | |||||
| Linearity | Within ±0.5% of the full scale (in equivalent input) | |||||
| Transmission output | Number of outputs: 2 4 mA to 20 mA DC/0 mA to 20 mA DC, input/output isolated type Maximum load resistance: 900 Ω Transmission output range: Freely selectable within the measurement range (Negative terminals of each transmission output channel are connected inside and thus have the same electric potential.) | |||||
| Contact output | Number of outputs: 4 Alarm contact outputs (R1, R2, and R3) Contact type: relay contact, SPST (1a) Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load) Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis Selectable from the selected measurement, anomaly alarm, and maintenance. Alarm contact output (R4) Contact type: relay contact, SPDT (1c) Contact rating: 240 V AC, 3 A and 30 V DC, 3 A (resistance load) Contact function: selectable from the upper/lower limit action (ON/OFF control), delay, and hysteresis Selectable from the selected measurement, anomaly alarm, and maintenance. (However, R1 and R2, and R3 and R4 share the common contacts respectively.) | |||||
| Calibration function | Specific resistance: Based on the specified compensation coefficient for cell constant (parameter input) Temperature: Calibrated by comparing with the reference thermometer | |||||
| Communication output | RS-485 input/output | |||||
| Transmission output hold feature |
| |||||
| Self-diagnosis function |
| |||||
| Temperature compensation |
| |||||
| Temperaturecompensated range | 0℃ to 100℃ | |||||
