Kalstein turbidity meters: a comparison of the YR01842 and YR01841 models

Turbidity is a measure of light scattering that is caused by particles present in a transparent medium, and is one of the main metrics in environmental research and wastewater studies. Turbidity meters are essential to ensure the purity and wholesomeness of water, indispensable in fields such as medicine, the food industry and quality control. We will review two models provided by Kalstein: the YR01842 benchtop turbidity meter and the YR01841 portable turbidity meter.

Benchtop turbidity meter YR01842

This instrument is characterized by its accuracy and wide measuring range. The YR01842 has a range of 0 to 2,000 NTU (Nephelometric Turbidity Units), 0 to 500 EBC (European Color Units), and 0 to 9,999 ASBC (American Brewers System). This makes it a very versatile tool for measuring turbidity in a variety of applications.

The resolution of this meter ranges from 0.01 (0 to 99 NTU), 0.1 (100 to 999NTU) and 1 (1 000 to 2 000 NTU), ensuring accurate and reliable measurement anywhere in the range. Accuracy is ยฑ2% reading for the range 0-500 NTU, and ยฑ3% reading for 501 to 2,000 NTU. https://kalstein.pl/product/benchtop-turbidity-meter-yr01842/

This meter can be calibrated through 2 to 7 points, with calibration standards ranging from 0.02 to 2 000 NTU. The ability to perform a wide range of calibrations improves the accuracy and reliability of the results.

YR01841 Portable Turbidity Meter

The YR01841 portable turbidity meter has a similar configuration to the YR01842 model, although it has some differences. Its measurement range is 0 to 1,100 NTU, 0 to 275 EBC and 0 to 9,999 ASBC. Although the range is somewhat lower, it still offers a wide measurement capability, covering most of the necessary applications.

The resolution of this meter is also 0.01 (0 to 99 NTU), 0.1 (100 to 999NTU) and 1 (1 000 to 2 000 NTU). Accuracy is ยฑ2% reading for the 0-500 NTU range, and ยฑ3% reading for the 501 to 2,000 NTU range.

This meter can be calibrated through 2 to 5 points, with calibration standards similar to those of the YR01842 โ€“ from 0.02 to 2 000 NTU. https://kalstein.pl/product/portable-turbidity-meter-yr01841/

Comparison and conclusions

Both meters exhibit high accuracy and measurement capability, although the YR01842 offers a slightly higher range. The main difference between the two models is their design: while the YR01842 is a benchtop meter, the YR01841 is a portable meter. This means that, in terms of portability and ease of use in the field, the YR01841 has the advantage.

In addition, both instruments have the ability to measure total suspended solids (TSS), which further extends their usefulness in a laboratory or field research environment.

In conclusion, the choice between the YR01841 and YR01842 will depend on the userโ€™s specific needs in terms of portability and measurement range. Both instruments represent highly competitive options for turbidity measurement.
