In-Situ AquaTroll 400 Water Quality Meter

A multi-parameter water quality meter with optical DO and smart phone / device connectivity. With the Bluetooth transmitter, data is wirelessly sent to your Android or ios device. The Low Flow Sampling wizard accurately calculates stability based on parameters you provide. 

Optional cables for lowering down 2" or larger wells for direct measurements. 

Be Mobile

•  Use the AquaTroll 400 anywhere: Reduce field equipment requirements for routine monitoring from low-flow sampling events to aquaculture spot checks.

• Instantly collaborate with colleagues: Use a wired or wireless connection to send real-time snapshots of data.

• Streamline data management: Consolidate all site information on your smartphone and tag data with site photos and GPS coordinates. Log data to your smartphone and download results in a standard .csv file format.
