4.2 Calibration Procedure 1） Apply a little silicone oil on the calibration vial and wipe clean with 3) Open the flip cover and put in 2）Press key to turn on the the soft cloth to obtain an even 0.02NTU calibration vial. Align the meter. -
Page 10: Calibration Standards
4.3 Calibration Standards TN400 turbidity meter adopts US EPA certified Reagecon high molecular weight polymer turbidity standard solution. Compared with traditional Formazin standard solution, Reagecon standard solution has a lot of advantages, such as non-toxicity, high accuracy, long shelf-life, traceable to NIST and so on. The standard solution supplied in the TN400 turbidity meter kit has a shelf-life longer than 12 months (from the date of manufacture). -
Page 11: Measurement Preparation
5.2 Measurement Preparation 1) Collect sample solution in clean vessel, fill sample solution to four fifths position of sample vial (approx 18ml), see diagram-5, screw the vial cap tightly. 2) Before measuring, please make sure sample solution is uniform. Slowly roll over the sample vial to make sample solution uniform, and wait air Diagram- 5 bubble to eliminate completely. -

recommended to use silicone oil supplied with the instrument. 3) Mix and Degassing Samples should not be violently shaken or agitated. It is recommended to slowly roll over sample vial to make solution evenly; Air bubble in solution will cause big error to turbidity measurement.
