How it comes together

From your water.
To your next decision.

1

Sample at the source

Choose a representative point in the water system. Plan the sample feed, drain and service access before installation.

2

Bring readings together

The analyzer brings the selected measurements to its local touchscreen. Probe selection and calibration follow the agreed configuration.

3

Connect the next step

Use the specified 4G or RS485 / Modbus connection to bring readings into the agreed monitoring setup.
