Unidata offers a wide range of instruments to suit measurement of conductivity, evaporation, water depth and temperature. In addition to those water instruments, Unidata also offers the Starflow, an intelligent ultrasonic Doppler velocity, depth and water flow measurement system as well as Starflow QSD ultrasonic Doppler velocity and depth SDI-12 Instrument.
For shallow water (up to 20 metres), the full range of Hydrostatic Water Depth Probes 6542D will provide reliable and accurate measurement. For a wider range of water depth (up to 65 metres) and higher accuracy of data, the Precision Water Level Instrument 6541C which is available in several different configurations offers an excellent solution. For water quality measurement, consider using the Water Electroconductivity Instrument 6536E, the pH and ORP Probes 6528 or the dissolved oxygen probe 7422
