Fits handheld noncontact RPM checks where you need a Monarch Pocket Tach 99 (PT99) optical tachometer covering 5 to 99,999 RPM with ±0.01% accuracy and Max/Min/Last memory.
Key advantages
- Range — 5 to 99,999 RPM
- Accuracy / resolution — ±0.01% of reading or ±1 digit; auto-ranging 0.001 to 1.0 RPM
- Optics — Red LED light source (not laser); ≤36 in at ≤30° off perpendicular
- Memory — Maximum, Minimum, and Last Reading
- Power — 2× AA; ~60 h continuous typical
Typical applications
- Machine RPM checks with reflective tape.
- Maintenance routes needing Max/Min capture.
- Sites preferring LED over Class 2 laser.
Selection guide
- LED vs laser — PT99 LED vs PLT200 laser reach
- Distance / angle — ≤36 in / ≤30°
- Memory needs — Max/Min/Last
- Power — AA alkaline life
Common mistakes
- Expecting laser range of PLT200.
- Working beyond 30° off perpendicular.
- Missing reflective target tape.
