Same highly linear, stable electronics as 130B-24.
Designed for measuring blocks above 4.000" (100 mm) but capable of checking shorter blocks as well.
Linear ball slide for smoothly moving long gage blocks without danger of tipping them over.
Large platen area for staging blocks before measurement - critical to achieving thermal equilibrium with the gage.
Fully counterbalanced "floating measurement frame" to isolate measurements from vibration.
Open frame design allows comparison measurement of large disks, up to 24" in diameter.
Can be operated from the same computer as 130B-24.
Scale on left-hand post allows rough positioning, and micrometer-style spindle allows smooth, easy mechanical fine-adjustment.
