Probe Designs and Ordering 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.
