Prism Instruments was started in 1991 to sell and service the best colour measurement solutions available to Canadian companies. Everything is supported out of our Pickering Ontario office. Equipment can be serviced at the customer site or it can be returned to our office for calibration or repair. Since it is serviced in Canada you never need to send anything back to the U.S. and you can avoid delays due to customs.Prism Instruments was started in 1991 to sell and service the best colour measurement solutions available to Canadian companies.
