Karl Deutsch Deutrometer 3873 Field Strength Meter

Karl Deutsch Deutrometer 3873 Field Strength Meter

Simple and Convenient with Automatic Measurement of Magnetic Field Strength, UV & White Light

Rugged & User Friendly

The Deutrometer 3873 is a professional instrument that quickly and easily measures magnetic direct and alternating fields in the low frequency range (20 Hz to 500 Hz). It provides simple and convenient field strength measurement and monitoring of limit values.  It is also possible to measure UV and white light with the DeutroLight special probe. The Deutrometer 3873 has an operating mode that recognizes and measures both magnetizing strength and residual field strength immediately one after the other, eliminating the need for switching manually and thus reducing false measurements due to incorrect gauge selections. The simultaneous representation of readings and maximum values as well as the selectable visual and acoustic limit alarm complete the practical qualities of the new gauge.

Applications

  • Measuring the tangential field strength during magnetization
  • Measurement of the residual field after demagnetization
  • Can be used as a flux density meter (tesla meter)
  • Measures UV irradiance and illuminance of residual light with special probe.

UV & White Light Measurement

For a standard MT or PT test, the viewing conditions need to be monitored. A special probe, the DeutroLight sensor, enables the combined measurement of UV and white light illuminance. Here, the lux illuminance measurement is not influenced by the UV radiation, so that a measurement (in compliance with ISO 3059) is possible even when the UV lamp is switched on.

 

Operating Modes

  • Measurement of alternating field / direct field (automatic detection)
  • Measurement of alternating field / direct field (automatic detection) with monitoring of limit values
  • Measurement of direct fields (e. g. for residual fields)
  • Measurement of alternating fields (e. g. measurement of magnetization strength)

 

Probes

  • Angled 90° (Order #: 3873.101)
  • Straight (Order #: 3873.201)
  • Angled 90°, for transverse fields (Order #: 3873.301)

When using the device in oily environments, the paraffin resistant probes are recommended:

  • Angled 90°, paraffin resistant (Order #: 3873.111)
  • Straight, paraffin resistant (Order #: 3873.211)
