Turbidity is measured according to ISO 7027 by nephelometric means (90° scattered light). The infra-red light-source permits measurement of coloured and colour-free samples. The automatic measurement range detection facility (Autorange) enables direct turbidity measurement from 0.01 to 1100 NTU.

• Automatic overall range adjustment with standard set T-Cal
• High accuracy
• Suitable for laboratory and mobile use
• Memory storage of up to 1000 data-sets
• Real-time clock
• Waterproof sample chamber and housing

Acrylic/PP.

Imhoff pattern, solid grey PVC. Stable design.

The microprocessor-based waterproof Infra-Red Turbidity meter TN-100 is easy-to-use and meets all rigor of rugged field applications. Using an Infrared light source, it delivers laboratory accuracy with a resolution of 0.01 NTU across an extended range of up to 20 NTU (Nephelometric Turbidity Units).

• IP67 Waterproof and Dustproof, easy cleaning and maintenance
• Automatic Push-Button Calibration (4 points) for unprecedented full-range accuracy
• Power-saving feature allows over 1200 measurements
• Large Easy-to-Read Display for optimum viewing of measurements with user-friendly message codes for easy troubleshooting
• Meets Performance Criteria as specified by ISO 7027 (DIN EN 27027) method

Battery-operated portable turbidity meter with infrared LED for nephelometric measurements as per ISO 7027/DIN EN 27027 (EN ISO 7027) or as a white light model with tungsten lamp as per US EPA. It is handy, light and simple to operate and is suitable, primarily for applications to monitor > 1 NTU. With smaller samples of 15 ml, it is also very suited for applications in fermenters and cell cultures at good precision.

Scope of delivery: Turbidity meter in a handy small case with quick instructions, calibration standards 0.02-10.0-1000 NTU, empty cuvettes and batteries.

The turbidity meters Turb^® 430 IR acc. to DIN ISO 27027 and Turb^® 430 T acc. to US EPA 180.1 meet the requirements of the nephelometric measurement at 90° stray light for drinking water with highest precision, especially in the range < 1 NTU. The measuring range comprises 0-1100 NTU/FNU with automatic measuring range switching and is therefore suitable for water analysis as well as quality control, such as gasoline, cell cultures, as well as in the food and beverage industries.
The measurement and automatic 3-point calibration runs self-explanatory and menu-controlled. The calibration takes place via an AMCO Clear^® standard set (0.02-10-1000 NTU). Up to 1000 data sets including sample ID numbers can be stored and later put out GLP-compliant via the PC software LSdata. The quality assurance of the measured results is supported by calibration interval setting with documentation.

Scope of delivery:
Turb^® 430 IR / Turb^® 430 T: Turbidity meter with calibration set 0.02-10.0-100 NTU
Turb^® 430 IR/SET / Turb^® 430 T/SET: Turbidity meter in case with table insert, calibration set 0.02-10.0-100 NTU, PC software LSdata, accessories
