Anritsu HHT Series ordering and selection information

Selecting an HHT Surface Probe

  • Operating range: Provide the lowest, normal and highest surface temperatures. The HHT-5 examples start at 300°C, so they should not be selected simply as a wider-range substitute for HHT-4.
  • Measurement access: Describe the target surface and available approach to help select the probe geometry and reach.
  • Contact conditions: Tell us whether the surface is stationary or moving and whether measurements will be occasional or repeated.
  • Instrument compatibility: Provide the thermometer model so its Type K input, temperature range and connector can be checked.

Probe life depends on operating temperature and contact conditions. Anritsu's published contact-endurance figures decrease at higher temperatures; they should not be treated as a service-life guarantee.
