Sontek Flow Tracker
泭
Widely regarded as the 'go to' method for gauging streams and small rivers, the flow tracker uses Doppler technology to measure water flow to a very high resolution and accuracy. The unit has built-in data logging and calculations to record raw measurements and calculate discharge.

CTD loggers
泭
Conductivity, temperature and depth are all useful parameters to measure for long-term recording of stream conditions, especially in coastal areas. We have several different CTD units to choose from to suit a variety of situations and research needs.

Manta water quality sonde
泭
This self-contained measurement and recording system can be used for mobile measurements or fixed location measurements. It measures all of the following parameters: temperature, conductivity, dissolved oxygen, pH, REDOX potential & Nitrates.
泭
Current meters
泭
We do have traditional stream current meters including pygmy and Ott meters. When quick measurements are required, perhaps in difficult to reach locations, our flowprobe 101 meters are lightweight & easy to use. Where time series data is required, we have a valeport model 106 current meter, or can use the ADV or ADCP (see our coastal section for details) if conditions are appropriate.
泭
Sampling
泭
We have several water samplers designed specifically for streams and rivers, including an automated sampler where time series samples are required. Where bed-load sediment is of interest, we have several options for in-situ sample collection and our in-house engineer can design and build frames and bracketing systems to suit most locations.

Sediment analysis

See our Sedimentology equipment泭section for details on a wide range of lab analysis options.
