Turb 430 – Lab Quality Portable Turbidity Meter

Turb 430 IR is a portable turbidity meter from WTW, designed for use in the measuring range from 0 – 1100 NTU/FNU. Fully compliant to DIN EN 27027/ISO 7027 the Turb 430 IR has a new optical design with infrared LED. The instrument is optimized for applications demanding high mobility, e.g. drinking water analysis and process control. Having been developed together with the multi-parameter photometers of the pHotoFlex Series, the Turb 430 IR offers a number of innovations compared to conventional instruments.

• Innovative new optical design to minimize stray light interference.
• Precise measurement in the critical range below 1NTU.
• Calibration interval and protocol.
• Data storage of 1000 values.
• GLP compliant data export with date, time, and identification number.
• RS 232 interface
• LabStation (optional) for exceptional ease of use in lab.

AMCO-Clear Standards (0.02–10–1000 NTU) for the automatic 3-point calibration are included in the delivery package. These standards are traceable to Formazine and are accepted as primary standards according to US EPA. They offer many benefits over formazine, including, high accuracy, longer stability and most importantly they are no threat to health and safety.
For measuring below 1 NTU, the units are supplied with special application notes for calibration. Accuracy and precision in the low measurement range are seen to be greatly increased. The Turb 430 IR is equipped with a rechargeable battery and a universal plug, or alternatively, the user can use the LabStation (optional) with the rechargeable battery set. The LabStation effectively makes the Turb 430 IR a small benchtop instrument with a complete data evaluation system.

A further model, the Turb 430 T with tungsten lamp and a measurement range of 0-1100 NTU has been designed to fulfil the US EPA 180.1 requirements and to meet the demands for stray light of Pharmacopeia 5.0 providing precise and highly reproducible results notably in the range below 1 NTU.
