Manufactured from borosilicate glass 3.3 according to sedimentation tests according to DIN 12672 standard. Featured with volume graduation of 1000 ml. Volume graduations and inscriptions are printed with white enamel.

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

For determining the depth of visibility and light permeability of water. Sturdy design made of strong, hard-wearing plastic. Lead weight for better lowering. The approx. 15 cm high rod is fitted with an eyelet for fastening the lowering engine. The lowering line is marked in intervals of 100 cm with figures from 1 to 10 and in between additionally with line markings each 50 cm for better reading of the depth of visibility while the disk is being lowered.
Lowering line, please order separately.

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

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

Highly accurate turbidity standards composed of suspended microspheres, suitable for Instrument calibration and control of all turbidity meters. Stable, shelf life of 2 years (from Date of Manufacturing). NIST traceable, US EPA approved and tested in compliance with ISO 7027. HDPE bottles of 100 ml.

Two ranges available:

• Ratio range for Ratio Turbidity Measuring instruments (measure of the scattered light from the sample at a 90° angle from the incident light, plus at additional angles (several detectors)
• Non Ratio for Non Ratio Turbidity Measuring instruments will measure the scattered light from the sample at a 90° angle from the incident light (one detector)

Calibration kit includes 4 x 60 ml standard solutions (0.02, 20.0, 100, 800 NTU).

Each set contains one sealed cuvette with the indicated concentrations.

Transparent, sturdy frame for three 1000 ml Imhoff sedimentation vessels.

The portable turbidity meters are characterised by the use of Multipath 90° BLAC^® technology. Samples with low and high turbidity can be analyzed entirely nephelometric (Detection angle 90°) with the highest accuracy over the complete measuring range up to 4000 NTU. By eliminating stray light, highly accurate results are achieved for low turbidities down to 0.01 NTU.

• High performance optics to ensure accuracy
• Elimination of stray light through light absorbing trap (BLAC^®)
• Intuitive colour touch screen with animated guided procedures and straightforward data management, multilingual
• Visual warning for out-of-tolerance readings
• Data logger for 250 measurements plus all calibrations, verifications and factory recovery procedures
• 3 different modes: single, signal averaging, fast settling
• USB-C interface
• Optional operation with rechargeable battery pack or mains adapter
