Ballast Check 2

The Ballast Check 2 is a lightweight, highly portable handheld Fluorometer.

Ideal for quick indicative compliance checks of ballast water., the Ballast Check 2 is Factory calibrated, ready for use right out of the box and optimized for the ballast water D2 regulations.  No additional calibration is required.  All required accessories are included.

The precision and accuracy of the Ballast-Check 2 have been independently verified and demonstrated 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 cannot be edited.

Ballast-Check 2 is ideal for quick on-the-spot indicative compliance tests of ballast water.
