Test Piece and Contact Liquid for ATAGO ABBE Refractometers.

* NIST-traceable calibration certificates are available separately for purchase. Contact ATAGO for details.

Test piece with m-naphthalene

Users who measure solid sample by NAR-1T, 2T, and 3T need to adjust the scale by measuring the Test Piece. Also, for High-Refractive Index model, NAR-4T users need to adjust the scale by the Test Piece. The Test Piece comes with ATAGO ABBE Refractometers as an accessory.

Test piece for measurement of film

Contact Liquid/Test Piece for film sample measurements. Film samples usually do not have enough thickness to obtain incidence light. Contact Liquid/Test Piece aids obtaining the light. Please select one which have has higher Refractive Index than the film samples. One Contact Liquid/Test Piece comes with ATAGO Multi-Wavelength ABBE Refractometer.
