Multi-parameter water quality sonde

iLab 901

Up to seven water quality parameters at once, from one rugged sonde and its handheld.

Up to seven at onceParameters measured together, from a list of thirteen
Cleans itselfSo the data stays accurate for longer
100,000+ readingsStored on the handheld
IP68 sondeRated to 30 m, with an IP67 handheld
Modbus RS485On a 9 to 36 V DC supply or its own lithium cells
GPS and USBBuilt in, with Bluetooth as an option

The iLab 901 is a multi-parameter sonde for long-term water quality monitoring. Fit it with up to seven sensors, chosen from thirteen measurements, and it reads them all at once.

It cleans its own sensors, so the data stays accurate for longer. Set the sampling interval to suit, and the sonde makes the most of its batteries.

The handheld shows each reading on a 3.5 inch colour screen and stores more than 100,000 of them. GPS and USB are built in, and Bluetooth is an option.

Seven at onceOne sonde carries physical, electrochemical, optical and ion-selective sensors, picked for the job.

Cleans itselfA self-cleaning system keeps the sensors clear, so the iLab holds accurate data for longer.

Long deploymentsSet the sampling interval to suit, and stretch the time the sonde runs on its own lithium cells.

Readings in your handA 3.5 inch colour screen with an adjustable backlight shows results live, with fast processing on board.

Built for the fieldAn IP68 sonde and an IP67 handheld with high-impact rubber gaskets and a shape that’s easy to hold.

Located and connectedGPS and USB are built in and Bluetooth is optional. The sonde speaks Modbus over RS485.

Thirteen measurements. Fit up to seven.

Each iLab 901 is fitted with the sensors your program needs. Conductivity also gives salinity and total dissolved solids.
