I have an older Optical Comparator / item. How much is it worth?

There is no pre-established value on older optical comparator. Many factors can affect the value of an older optical comparator; age, model, condition, etc. Thus, estimating value can be very subjective. We recommend you sending us detailed information including the model and serial number of the optical comparator, as well as many digital images of the unit for consideration of pricing.

We have various comparators that have certifications. How often do they need to be updated or re-certified?

Anyone can improve their efficiency and reduce costs by using a properly calibrated unit. Each company determines their own requirements by typically doing analysis of use to define which Optical Comparatorss can be calibrated less frequently and which should be calibrated more frequently. Calibration needs vary from customer to customer based on their usage, certifications, needs, and many other factors.
