2、 Product Introduction

（1） TheTurb 550

Adopting internationally recognized standards 90 Degree scattered light turbidity method, using tungsten lamp as the light source, in compliance with the US Environmental Protection AgencyUS EPAAccording to the standard regulations, automatic 3Point correction,RS232Output and built-in real-time clock, calibration interval can be set to prompt users when to check. Wide testing scope, from0.01 …1000 NTUAutomatically switch the range between them. The dual row display screen can simultaneously display the current test value and previous test values for easy comparison. Standard equipment: concise operation card,2 Root empty test tube,3 A second level standard solution（0.02–10.0–1000 NTU）And the test tube wiping tool.

（3） TheTurb 555

High precision laboratory turbidity meter with a wide testing range, from0.0001 to 10000 NTUCapable of almost all application scenarios, from pure water, drinking water to wastewater. Instrument belt 4 A sensor that can not only test 90 Scattered light and 180 Transmitting light can also achieve ratio testing, improving the ability to resist stray light and chromatic interference. Testing units are optional EBC(European Beer Brewing Association), can be used in the beer industry. The instrument is equipped with backlight display, making reading convenient and simple. The testing resolution is high, and users can choose the appropriate resolution. The instrument adopts a menu based operation, which is very simple to operate. In addition, this instrument has unique featuresAQAFunction can ensure testing accuracy and stability, for example, users can set calibration intervals and schedule calibration. Complete supply, including all accessories such as standard solution and blank colorimetric tube.
