Two-Way Packaged Water Quality Station
Multi-parameter water quality on the two-way 50388 Data Transmitter. The SDI-12 water-quality package carries up to six probes — temperature, conductivity, pH, dissolved oxygen, turbidity and element-specific options — alongside a submersible pressure transducer for level, with a return path for polling and control. Consult HydroLynx to configure the probe set to your monitoring plan. Commands over the return path are protected by the ALERT2 protocol's encryption and authentication — how two-way networks stay secure →

Which variant do I need?
| If your site… | Order | Why |
|---|---|---|
| Only needs to report in (one-way) | 5391/A2 | The one-way sibling on the 50386 platform — see the 5391 |
| Needs polling, remote reconfiguration or control | 5891/A2 | Two-way SCADA on the current ALERT2 standard |
| Joins a legacy ALERT network with SCADA needs | 5891 | Matches existing receivers; upgradeable later |
| Wants rainfall from the same standpipe | 5891/5054TS | Rain-gauge top section replaces the standpipe cover |
