Solinst Eureka EasyProbe
Cost-effective multiparameter water quality sonde in two versions: EasyProbe20 measures temperature, dissolved oxygen, conductivity and pH/ORP, and EasyProbe30 adds turbidity.

Part no.: Manta+30A
Multiprobe with wipered turbidity, temperature, pH, conductivity and optical DO. Light enough for spot checks and profiling, tough enough for extended deployments.
Prices are given in the quote we send you.
Manta+30 comes in two configurations, 30A and 30B. Both carry wipered turbidity, temperature, pH, conductivity and DO as standard, with ORP and depth as options. The 30B also takes an ion selective electrode (ISE) or a TDG sensor.
The wiper cleans the turbidity sensor and its extension brush also wipes the DO sensor and fluorometer. Any fluorometer, for example chlorophyll or blue-green algae, can replace the turbidity sensor.
The optical DO cap lasts 5+ years and the pH reference is refillable, keeping running costs low. Connect it to a field display, a battery pack or a telemetry station.
