Model# 505-746. Passed calibration last time they were in service during my inspection days. The calibration tech wrote the MT&E number on them which I couldn’t believe but I dare not try to remove it. I did try to remove my name from the case but no avail.

I bought these in 2016 and last used them in 2018. I would say these were used weekly and not daily during that time.

150$ firm out the door.
