The gauges are easy to use and the user can make all the necessary adjustments with the aid of a menu-changes can therefore be implemented quickly and simply with a minimum amount of fuss. Both gauges have a large measuring range of 0 to 5 mm to offer and can therefore be used for a wide variety of applications. Modern electronic and the robust instrument housing guarantee an extended lifetime for the high precision instruments. These features as well as others, make the practical hand-held pocket gauges an indispensable aid in the quest for quality control and other applications.

Coating thickness gauge
SaluTron® D4 / D5

Precise coating thickness measurement on ferrous or non-ferrous substrates

The gauge SaluTron® D4 measures all non-magnetic coatings such as sythetics, lacquers, enamels, copper, chromium, zinc, etc. on steel or iron.

The gauge SaluTron® D5 measures all isolating coatings such as lacquers, synthetics, enamels, paper, glass, rubber, etc. on copper, aluminium or brass. This includes eloxal coatings on aluminium as well.

Features and equipment

  • Easy to use
  • Large measuring range 0.00 to 5.00 mm
  • High accuracy
  • Measurement type-single-point or continuous
  • Vibrations do not influence the measurements
  • Wear resistant, spring-loaded ruby probe
  • Measurement result can be displayed in µm or mils
  • Gauges can be switched on/off manually or automatically
  • Visual alarm if the gauge is placed on incorrect substrate or if coating thickness exeeds the maximum range
  • Integrated probe-for single-handed use
  • Easy setup
  • Requires no timely re-calibration for different material
  • The V-groove assists in the placement of the probe on spherical surfaces (rods, pipes, etc.)

Mini-Infrared-Printer SP 100

Mini-Infrared-Printer SP 100

The infrared pocket printer SP 100 completes the functions of ComBi D3®. An adapter enables wireless data transfer to print out measured and statistic values.

Other features are:

  • Thermal printing process
  • Magnetic surface to stick on metal
  • Universally applicable with other gauges
  • High printing speed (one print line = 24 signs per second)
  • Transfer distance from gauge to printer: up to 4.5 m
  • Very robust and handy
  • Size (length x width x height): only 15.5 x 9.2 x 6.5 cm or 6.1” x 3.6” x 2.5”
  • Independent of mains supply (four AA Alkali-batteries)

The SP 100 sticks on metal surfaces. Two strong magnets are embedded underneath the rubber coating.
