The C6P™ Submersible Fluorometer includes up to six optical sensors, each configured for a specific application. Excitation/emission wavelength pairs, spanning the light spectrum from deep ultraviolet to infrared define each application. All sensors are factory set to provide excellent sensitivity and a broad range of detection. Every C6P comes with a factory-installed temperature sensor with an option to add a depth sensor. Internal data storage capacity combined with an external submersible lithium ion battery allows the C6P to run as a self-contained instrument for any deployment interval, short or long-term.

C-sense probes are compact, lightweight sensors for measurement of the partial pressure of gas in liquids. Designed for applications involving immersion in water, oil, or water and oil mixtures, the sensors combine an oil-resistant interface with a compact, temperature-compensated non-dispersive infrared (NDIR) detector. C-sense ships with a copper antifouling guard which minimizes biofouling as well as protects the membrane. Designed for integration, C-sense enables pCOâ‚‚ monitoring at a significantly lower price than traditional pCOâ‚‚ sensors.

Trilogy is a powerful yet easy to use instrument that offers many benefits for benchtop analysis of samples. Its all solid-state design (no moving parts) utilizes light emitting diodes, sensitive photodiodes, solid glass filters, and electronics to ensure reliable and repeatable readings with no instrument drift. Sensitivity is maximized and pre-set providing a broad measurement range from minimum detection levels to maximum linear concentrations without instrument adjustments. Up to 18 different calibrations can be stored, each calibration performed with up to five concentration standards. Data can be output directly into an Excel spreadsheet during measurements via USB or serial connection.

Quick Indicative Ballast Water Compliance Checks. Ballast-Check 2 is a small, lightweight, highly durable handheld fluorometer ideal for quick indicative compliance checks of ballast water. Factory set and optimized for the ballast water D2 regulations, the Ballast-Check 2 is ready for use right out of the box; all accessories are included and no calibration is required. Precision and accuracy of the Ballast-Check 2 have been independently tested and shown to correlate well with microscopy when estimating cell counts even after UV treatment. Simple one-button measurements display estimates for both algal abundance and algal activity, while also providing ship crew or port state control with an indication of risk for exceedance of the regulation. Results are logged internally and can be downloaded as a PDF report which can not be edited. Ballast-Check 2 is ideal for quick on-the-spot indicative compliance tests of ballast water.

We are very sorry to announce that after almost 20 years of manufacturing the 10AU Field Fluorometer, we are no longer able to purchase some of the parts. We are very sorry to say we can no longer build new units.  We will continue to support and repair 10AUs in the foreseeable future. Due to material obsolescence we are not able to repair 10AUs built prior to January 1,1999 starting with S/N 6720.
