1. Introduction
1.1 Description
The Turner Designs Digital C-FLUOR Submersible Probe is an accurate single-
channel detector that can be used for many different applications. Digital CFLUOR can be integrated into multi-parameter systems from which it receives
power allowing it to output digital ASCII data as concentration estimates for a
fluorophore of interest.
Digital C-FLUOR Probes are factory calibrated and a probe-specific calibration
certificate is included with each probe. The certificate contains information that
states the probe’s minimum level of detection and range of concentrations that
can be measured for the specific application.
Digital C-FLUOR Probes are manufactured with a Titanium housing and
connector, ideal for long-term deployments and able to withstand most corrosive
environments. It is available without a connector for integration flexibility; see
Section 2.2 for part numbers.
NOTE: Digital C-FLUOR Probes cannot be used with the C6 Multi-Sensor
Platform, Cyclops Explorer or Databank Handheld Datalogger.
