Portable turbidity meter ECOSTAB TB251
Portable turbidity meter ECOSTAB TB251 Designed for turbidity measurements ranging from 0.2 to 1000 NTU (NTU) in a variety of applications, in the field, environmental monitoring laboratories, water treatment, beverage production, etc. Uses an infrared light source, which is ideal for turbidity measurements of color samples, and a nephelometric method (90° scattering measurement) for turbidity determination in accordance with GOST R 57164-2016. The device is equipped with a large color TFT display with a clear image, graphic and text prompts during the measurement process, a GLP function and memory for storing data. The device memory provides storage of 200 measurements, the USB interface allows you to transfer data to a PC (with Windows-based OS). The device is equipped with the TruRead function, which automatically takes several consecutive readings and calculates their average, minimum and maximum values, and displays each set of data in the form of a summary report. TruRead is the optimal way to determine the true turbidity of a sample, especially for samples with rapid settling and continuous changes in measured values. The device has zero point calibration and a built-in signal with indication of zero point calibration error, which ensures high measurement accuracy for solutions with low turbidity values. Applications: Water supply. Control of technological processes. Laboratory analysis. Drinks and juices. Treatment facilities. Drinking water. Food industry. Equipment for water utilities. Natural water. Environmental monitoring. Basic package: turbidity meter; flash drive with software; USB cable; 5 bottles of polymer standard AMSO turbidity solutions (0.02 NTU (EMF), 20.0 NTU (EMF), 100 NTU (EMF), 400 NTU (EMF), 800 NTU (EMF)); vials for samples Ø25×60 mm, 18 ml (6 pcs.); silicone oil for cleaning; microfiber cloth; 4 AA batteries; durable portable case; instruction manual.
