〈Catalog〉Modular Water Supply Quality Monitor GX-100
Interface Module: Displays measurement values. Also possible to communicate with mobile devices and PCs.
| Product name | Modular Water Supply Quality Monitor |
|---|---|
| Model | GX-100 |
| Measurement items | Turbidity, color, free residual chlorine, water pressure, pH, conductivity, water temperature (Flow rate can also be selected and displayed (reference value)) *The measurement subject is tap water whose measurement item values are within the ranges stipulated in the Japanese drinking water testing method. |
| Measurement method | Refer to Table 1 |
| Measurement range | Refer to Table 1 |
| Repeatability | Refer to Table 1 |
| Display method | i)Display of each component by LCD on the interface module ii)PC display and operation is also possible via USB connection (*) iii)Display and operation on mobile devices is also possible via Bluetooth® connection (*) *A dedicated app is required. Up to eight items (including flow rate) can be displayed simultaneously. |
| Calibration method | Refer to Table 1 |
| Automatic zero calibration | (Turbidity, color, free residual chlorine) Calibration method: Filtered water sample Calibration Start method: Calibration starts with an internal timer and Modbus® communication Calibration period: 1 to 9999 hours (arbitrary setting) Calibration time: 20 minutes |
| Automatic drainage | Start method: Drainage starts with an internal timer and Modbus® communication Drainage period: 1 to 9999 hours (arbitrary setting) Drain count: 1 to 9 times (arbitrary setting) Drain time: 9 to 45 minutes |
| Cleaning method | Turbidity, color: Continuous cleaning of cell window with wiper Free residual chlorine: Continuous cleaning with beads |
| Sample water conditions | Temperature: 0 to 40℃ (should not be frozen) Pressure: 0.1 to 0.75 MPa Conductivity: 100 μS/cm or more Amount introduced into the analysis section (flow rate): 80 to 100 mL/min ・When test-running, be sure to flush the instruments thoroughly before passing water through them. ・Be sure to provide a bypass for the piping leading to the instrument. ・If there is a risk of the sample water freezing, take measures by using insulation and heat retention device. ・Water samples measured with this device cannot be used for distribution. ・To keep the flow rate stable, avoid sudden fluctuations in water pressure. |
| Communication | Interface: RS-485 communication (Modbus® protocol) Communication speed: 19200 bps *Can be changed (2400 bps to 230400 bps) |
| Function | Liquid leak detection function |
| Data memory (When SD card is inserted) | The measured values of the measurement items are stored in the SD card in the interface module. Memory interval: 1 second, 1 minute, 1 hour (every hour on the hour) Data memory time: 1 second intervals - approx. 99 days 1 minute intervals - approx. 99 days 1 hour interval - approx. 1 year * The latest data will be stored in memory. |
