INTRODUCTION 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.

automatic mode, the data (also the measurement interface) will be automatically saved after each measurement. The instrument has two types of measurement mode: normal measurement (as in Diagram 4) and TruRead measurement (Diagram 5). in Diagram 4 means that 12 sets of data has been saved.
3.7 Setting for first-time use. The instrument should be fully charged before first-time use. Check and adjust settings for the following items: date, time, system language, etc. See the detail in Section 6 Parameter setup. CALIBRATION 4.1 Preparation for Calibration Calibration point The instrument has 5 calibration points: 0 NTU, 20 NTU, 100 NTU, 400 NTU, and 800 NTU.
④ Stability of calibration solutions The U.S EPA approved AMCO polymer standard calibration solution is very uniform and stable. It does not precipitate, drift or condense. It can be used directly without shaking or fliping the vial (to make the solution even). For polymer calibration solutions that have not been used for a long time, slowly flip the vial twice and let it stand for 2 minutes.
5) Place the 20.0 NTU calibration vial in the sample vial holder, press to start 20 NTU calibration. After calibration is done, press to confirm. The instrument will return to the calibration menu (see diagram on the right side). The OK sign indicates that 20 NTU has been calibrated 6) If you want to continue to calibrate 100, 400 and 800 NTU, place the 100 NTU calibration vial in the sample vial holder and press...
• Using the same sample vial to calibrate and measure can eliminate the error caused by different vials, thus reaching higher accuracy. For example, add distilled water to 1 vial for calibration and then add sample solution to 1 vial for measurement. Note that the solution vial should be rinsed thoroughly when changing solutions.
5.2 Measurement Preparation a) Collect the sample solution with a clean container and add the solution to the 4/5 of the vial (about 18ml), see Diagram 7. Then close the lid. b) Before the measurement, users can slowly flip the sample vial a few times and let it stand for 2 to 5 minutes to eliminate potential air bubbles (see Diagram 8).
times in parameter setting P2, and read the average value each time to improve the measurement accuracy. Compare the maximum and minimum values at the same time. If the difference is too large, it means that the measured value is not reliable, the solution may be unstable or there might be other factors affecting the measurement.

7.3 Install Software The instrument uses Turbidimeter PC-Link communication software. It is only compatible with Windows-based operating system. The communication port is USB. Copy and paste the program files from the USB drive to the computer. Connect USB cable to the instrument and computer, open Turbidimeter PC-Link.exe, the instrument will connect with computer automatically.
LAMP REPLACEMENT 8.1 Light source check Observe the light source on the left side of the sample vial holder as in Diagram 11. Turn on the . The light source will light up for 5 seconds. If it’s not lighting up or it’s instrument, and press flashing, please replace the lamp.
The above limited warranty shall not cover problems caused by improper use, accidental damage, and unauthorized repairs. Oakton Instruments 625 E Bunker Court Vernon Hills, IL 60061 www.4oakton.com...
