   ProScale Model 250 Measuring System

ProScale Model 250 shown with Encoder and Guide Clip*


The ProScale Model 250 is an Absolute technology measuring system that is ideal for machinery applications or any measuring environment where the need to always remember its' position is important.
* The guide clip shown above is used to move the ENCODER.

Features:

  • No Gap to Set: All ProScale Encoders are "captive" on the measuring Scale so you never need to worry about setting or resetting the Encoder gap.

  • Battery Operation: Most Readouts available for use with ProScale systems operate on 2AA alkaline batteries or 1 long life Lithium battery.

  • Set and Forget: With Model 250, calibration settings are not lost due to power interruption.  The Model 250 will remember its place even when you change the batteries.

  • High Noise Immunity: With ProScale Absolute technology, the likelihood of motor electrical noise, magnetic fields, or power transients affecting the measurement accuracy is greatly reduced.

  • Wireless Flexibility: ProScale Encoders and ProScale Readouts can be equipped with our 2 way ProRF wireless data systems.

  • Scalability: The Model 250s supports multiple Encoders and Readouts operating simultaneously on the same Scale.

  • RoHS compliant: Lead Free Product

  • One year warranty for defects in workmanship.
