Fowler-Trimos 53-190-012 Mini-Horizontal System

The Mini-Horizontal TELS is the ideal instrument for checking small dimensions. It is part of the horizontal instruments family.

The Fowler/Trimos Mini-Horizontal is a complete system for accurately measuring small internal and external sizes with a single gage.

Sylvac’s electronic measuring system is recommended for use with the Mini-Horizontal because of its proven operational reliability. The display unit is the positive answer to a variety of measuring problems. In order to satisfy the demand of quality in production, a direct two-way RS232C data output allows connection to a printer or computer.

Mini-Horizontal Construction

  • Monoblock construction with probe guide track.
  • Adjustable end-stop with anvil location.
  • Control knob for the displacement of the guide track of the monoblock (probe release).
  • Adjustable measuring pressure device.
  • Location for different measuring features, i.e. electronic probes or indicators, 8mm diameter.
  • Interchangeable measuring anvils for external measurements (53-190-019 anvils—6.5mm diameter with tungsten carbide tipped measuring surface  are supplied as standard).
  • Interchangeable measuring inserts for internal measurements (53-190-020 Inserts—4.5mm diameter, rounded, are supplied as standard).
  • Vertically adjustable table for internal measurement, hard chromed and ground surface, supplied as standard.


  • Internal measurements:  .24″ – 4″ (6 – 100mm) depending on accessories used.
  • External measurements:  0 – 4″ (0 – 100mm). The effective measurement allows a range of 1″ (25mm) which corresponds to the range of Sylvac probe No. 54-618-500.
  • External measuring range is increased by displacing the end stock (direct zero setting or setting of a preselected value)
  • Internal measuring range is increased by displacing the measuring inserts (setting of a preselected value according to a ring gage)
  • Accuracy: Within .00006″ (1.5µ) — corresponds to accuracy of Sylvac probe No. 54-618-500
  • Resolution: Using Display Unit D50S No. 54-618-148, the resolution is .0001″ or .00001″ (.001 or .0001mm)
