Reference Samples




Included with your meter

Two reference samples are included with each tint meter.  One is lighter (65% to 80%), one darker (20% to 35%).  Your meter should read within plus or minus 2% of the printed number on each sample.  To verify that the tint meter is working properly, take a reading of the reference samples before use.



NIST Specifications

Each sample is individually checked on an NIST (National Institute of Standards and Technology) traceable spectrophotometer.  They are accurate to within ±1% of the printed value on each label.
