Hi guys,
Are you talking about the Test bar & prism?
Part No.:5811025.
If you are, this is not a tool related to calibration adjustments, merely for checking the tonometer.
More to the point, one would need the service details for calibration adjustment of the internals. Has anyone got this?
As with the Haag Striet slit lamps, does anyone possess the service manuals?
Jim
