Sigrist AquaScat 2
The Sigrist AquaScat 2 is a turbidimeter. It has one measurement channel and two analog inputs. The router reads it over Modbus; its web interface is not supported. The device page shows the latest value of each channel’s metric; there is no instrument Status card.

If it does not work
Section titled “If it does not work”| Problem | What to do |
|---|---|
| A channel shows no values | Check that the channel is mapped to a metric and that the instrument has that channel in use. |
| The measurement channel shows no values | Check that the instrument answers on Modbus TCP port 502 and that the router reaches its IP address. |
