Question
Why is the tolerance on our certificate for the TL23 calibration kits 5%?
Answer
The TL23 and 2100 series turbidimeters have a stated accuracy of +/- 2% when calibrated with a single calibration set (Product # 2662105, 2659505); the specification of 5% is the result of the additive variation of the instrument, the lot to lot production, and glass vial raw material.  Shelf life of the product is also considered in this specification.
