Labmicrometer - Model 900, 1600

The Standard of Accuracy

If a large direct reading range is important to you, choose the Labmicrometer Model 900 or 1600 measuring system. Designed for gage calibration laboratories and shop floor environments requiring precise internal and external measurements over long lengths.  Additionally, the Labmicrometer is ideal for use as a setting bench and adjusting instrument offering precision setting of inside and outside comparative measuring gages, micrometers, snap gauges, as well as other measuring tools. Common applications include measurements of end/length standards, long gage blocks, plug/pin gages, thread gages, and rings/discs.

Setting Bench Measuring Applications:

  • End Standards / Bar Gauges / Ball Bars
  • Cylindrical Setting Gages
  • Gage Masters
  • ID/OD Large Diameter Rail Gages
  • Setting Standards (Frames, Rods)
  • Snap Gages
  • Large Diameter Gages (special frames: bridge, hump, "C", donut, adjustable)
  • Dial Bore Gages / Swing Gages / Shallow Diameter Gages
  • ID/OD Adjustable Frames
  • Master Setting Bars / Setting Masters / CMM Masters / Precision Parts
  • Ring Gages
  • Threaded Rings & Plugs (NPT)
  • Tapered Rings & Plugs
  • Pin & Plug Gages
  • Taper Threads - Pipe Threads (API Gages)
  • Micrometers
  • Dial / Test Indicator & Dial Calipers
  • Electronic Vernier Calipers
  • Variable Screw Thread Gages
  • Taps, Dies, and Cutting Tools
  • Feeler Gages
  • Gears / Splines
  • Your Precision Parts

Features & Benefits of the Labmicrometer®:

  • Two instruments in one - calibration and setting bench instrument (hand held tools and preset indicator style gages)
  • Digital laser interferometer with zero Abbe offset - for maximum resolution, traceability, and performance
  • Wide direct-reading range - No remastering required over gage’s entire measurement range
  • Mechanical and thermal stability - Rugged, time-tested, cast iron base ensures reproducible results even in shop floor environments     
  • Variable force (standard) - Built-in, PC displayed force system offers measurement-independent adjustable force
  • Integrated probe lock (standard) - provides adjustable rigid positioning used for setting hand held adjustable gages
  • Two Point Calibration - Mastering with two, NIST traceable blocks, allows continuous, accurate measurement over the full direct reading range.  This provides significantly higher levels of productivity when compared to single point comparators. Only a handful of traceable masters, such as blocks, rings, etc. are needed (not included).
  • GageCal® Software - Microsoft Windows® based software reduces data entry, eliminates transcription errors, and speeds up measurements
  • Single-axis measuring table (standard) - Large surface area and T-slots provide for quick and simple fixturing and part alignment
  • Multi-axis measuring table (optional) - Offers five axes of motion for added control of part alignment
  • Bi-directional probes (optional) - Eliminates time-consuming setup changes
