Portable Turbidity Meter

Model: MA-267
$1015.0000
Price: $1,015.00

MA-267 Portable Turbidity Meter Kit quickly determines the amount of suspended solids in surface, saline, and drinking water. The meter features a multi-detector optical configuration for long-term stability. The ratiometric mode takes measurements from both the 90-degtree detector and the 180-degree detector for additional accuracy and repeatable results.

Equipped with a tungsten lamp, the meter meets the EPA 180.1 turbidity measurement method from 0 to 40 Nephelometric Turbidity Units (NTU). 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.

The meter features IP67 waterproof construction, large LCD display, auto-shut off, easy to use 6-button, menu-driven operation, and a data logger that can store up to 500 water test results. Seven user-selectable languages are pre-installed. The internal lithium ion battery is capable of up to 1000 tests before recharging is required.

Kits are supplied with 0, 1, and 10 NTU standards, sample bottle, six sample tubes, USB cable with wall adapter, and field-durable carrying case. SmartLink 3 software is available for data transfer to PC, purchased separately. A 12VDC Car Charger is also optional and sold separately.

Inquire about a separate LED light source unit that meets ISO 7027 standards.
