Description
New ratiometric design in one of the most innovative, waterproof, handheld meters available on the market!
The multi-detector optical configuration assures long-term stability and minimises stray light and colour interference. The new ratiometric design allows for easy and accurate testing. The nephelometric mode measures 0-40 NTU/FNU, ratiometric mode 40-1000 NTRU/FNRU and 1000-2000 AU. Now pinpoint the range of interest with better, more reliable results. Ideally suited for low-level drinking water applications, mid-range industrial applications, and high-range environmental applications.
