Portable Turbidity Meter

Model: MA-267
$1035.0000
Price: $1,035.00

Portable Turbidity Meter quickly determines the amount of suspended particles in water. This easy-to-use hand-held instrument accurately measures turbidity by the intensity of reflected light. Values are proportional to the quantity of suspended particles in the sample. The Portable Turbidity Meter meets EPA specifications for testing drinking water and is useful for measuring the clarity of aqueous solutions in general.

Equipped with a tungsten lamp, the meter meets the EPA 180.1 turbidity measurement method from 0 to 40 NTU (Nephelometric Turbidity Units). Radiometric mode measures 40-1000 NTRU/FNRU and Attenuation mode 1000-2000 AU. A tube-positioning ring limits tube variability for optimal sensitivity and accurate results.

Meter readings include range is 0 to 100 NTU and 0 to 2,000 AU (Attenuated Units). Accuracy is ±0.05 NTU from 0 to 2.5 NTU, ±2% from 2.5 to 100 NTU. Resolution is 0.01 to 1.0 NTU, dependent upon range. This model also performs ratiometric measurements with a range of 0 to 1,000 NTRU. Additional units of measure are ASBC (American Society of Brewing Chemists), FNU (Formazin Nephemlometric Units), or EBC (European Brewery Convention) units.

Features include IP67 waterproof construction, tungsten light source, large 6-line backlit LCD display, 500-point data-logging, auto-shutoff, and is CE marked. SmartLink 3 software is available for data transfer to PC, purchased separately.

The kit includes Turbidity Meter, 0, 1, and 10 NTU Calibrating Standards, sample bottle, six sample tubes, USB cable with a wall outlet adapter, and a waterproof carrying case.  A 12VDC Car Charger is also optional and sold separately.
