INT RODUCT ION   

Thank you for purchasing Oakton T100WL Portable Turbidity Meter (hereafter referred to as the 

instrument). The instrument uses tungsten filament lamp as the light source and 90° scattering method, 

which is compliant with U.S EPA 180.1 method for the determination of turbidity in drinking, ground, 

surface, and saline waters, domestic and industrial wastes. It is suitable for on-site and laboratory use. 

 

The instrument provides accurate results with simple measurement, calibration, and data management, 

giving you unparalleled confidence in test results and ease of use. 

 

Intelligent functions such as automatic calibration, operation navigation, parameter setup, real-time 

clock display, calibration date check, automatic power off, low voltage indication, and a replaceable 

tungsten filament lamp. 

 

Large TFT color screen with blue background for measurement mode, green background for 

calibration mode. 

 

Operation guidance and reminders in the process of calibration, measurement and parameter 

setting. 

 

TruRead measurement mode automatically takes multiple consecutive readings, and calculate their 

average, minimum and maximum value, as well as displaying each set of data in a brief test report. 

TruRead is a much better way to determine the true turbidity of your samples, rather than relying on 

just one reading. It's especially suitable for sample solutions with rapid settling and continuous 

measurement changes. 

 

Zero turbidity error reminder: the instrument has zero-point calibration and zero-point error reminder 

to ensure measurement accuracy for low turbidity solutions. 

 

200 sets of data storage with USB data output to PC (Windows-based). 

 

3.7V rechargeable lithium battery can supply power for over 20

 

hours of continuous measurement. 

The battery life is 5 times longer compared with tungsten lamp turbidimeter in the market using AA 

alkaline batteries. 

 

Multi-language operating system, including English, Spanish & Simplified Chinese. 

 

The instrument’s structure meets IP67 water-resistant grade and is suitable for use in harsh 

environments. 

 

Everything comes in a rugged carrying case, including accessories such as calibration solutions, 

test vials, USB charger, and more.
