RBR maestro³

The RBRmaestro³ – a multi-channel CTD+ logger for profiling or long term applications.

Contact us

The RBRmaestro³ C.T.D+ is a submersible instrument that is self-contained, accurate and autonomous. It can be deployed for a period of up to 5 years at 1 minute sampling intervals and data is retained in memory, even after the batteries (8 x AA cells) are removed.

Key Features

• Up to 240 M readings
• Up to 16 Hz sampling rate
• Realtime communications
• USB-C download
• Twist activation and Wi-Fi ready
• Supports 3 to 10 channel combinations

RBR’s multi-parameter, multi-channel loggers are designed to provide you with the flexibility to select the right combination of sensors for your water quality measurements. The choice of up to ten sensors can be integrated with the logger.

The loggers are available in two configurations: one for autonomous deployment and one for water column profiling. The recorders can be equipped with data and power connections to facilitate remote access or remote data acquisition.

There are several different sensors that can be used with the recorders, for example: Conductivity, Temperature, Depth, pH, ORP (RedOx), Dissolved Oxygen, Fluorescence, Turbidity, Transmittance, PAR, and others.

The RBRmaestro³ C.T.D+ conductivity, temperature and depth logger is built on the years of experience RBR has creating reliable and easy-to-use instruments. Salinity, depth, and speed of sound are derived through post-processing with the Ruskin software supplied.
