Supported Applications
The Omega HHT12 is a hand-held precision optical tachometer designed for non-contact measurements of rotational speed. The instrument measures speeds from 5 to 99,999 RPM at a distance of up to 36 inches (91.44 cm) from a reflective target and at an angle of up to 30° off perpendicular.
Key functional capabilities include:
- Recall of maximum and minimum values
- Tripod mounting for continuous measurements with lock-on capability
Operating Conditions & Performance
The HHT12 operates within an ambient temperature range of 40 °F to 105 °F (5 °C to 40 °C). Humidity limits are defined as a maximum relative humidity of 80% for temperatures up to 88 °F (31 °C), decreasing linearly to 50% relative humidity at 100 °F (40 °C); conditions must be non-condensing.
Performance specifications include:
- Speed Range: 5 to 99,999 RPM
- Accuracy: ±0.01% of reading or ±1 digit
- Resolution: 0.001 RPM to 1 RPM
- Operating Range (Distance/Angle): 36" (91.44 cm) up to 30 degrees off perpendicular
- Light Source: Red LED
The unit meets Installation Category II and Pollution Degree Level II per IEC 664.
