RBRmaestro³ C.T.D

RBR's Most Flexible, Option-Packed, Multi-Channel Logger

Ottawa, Ontario, CA

Description

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 a number of 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.

Features include:

240M readings
Up to 16Hz sampling
USB-C download
Twist activation
Wi-Fi ready
Supports 3 to 10-channel combinations
Realtime communication with USB, RS-232, or RS-485
Available Sensors: Conductivity, Temperature, Pressure (Depth), Dissolved Oxygen, Fluorescence, ORP, PAR, pH, Transmissance, Turbidity, and Voltage
