OTT Hydrometry (UK) will launch a major family of products at WWEM 2014 at stand 26; the Hydrolab HL4 multiparameter water quality sondes.
The HL4 builds on Hydrolab's reputation for accuracy, ease of use and reliability, offering users a multiparameter sonde that is easier to run, calibrate and service. The HL4 can be used as both a portable instrument and/or a continuous water quality monitor, and is ideal for surface water and near-coastal marine applications.
Each HL4 sonde is supplied with a temperature sensor and with 4 additional universal sensor ports, users can select Conductivity, pH, LDO (Luminescent Dissolved Oxygen), Depth and Turbidity, with depth as a further optional sensor.
Other features include a self-monitoring system for reports and troubleshooting, user-scheduled calibration and maintenance intervals, guided and semi-automated calibration routines and data storage, and sensor status is saved with every line of data.
