Fits rotational and linear speed checks where you need an AEMC CA1725 or CA1727—optical non-contact or contact adapter measurement to 100,000 RPM with frequency, period, and duty-cycle functions.
Key advantages
- RPM — CA1725 6–100,000; CA1727 60–100,000
- Accuracy — 1×10⁻⁴ of reading ± 6 counts
- Modes — RPM, linear speed, Hz, period, duty cycle
- Optical — 1–50 cm; ±15° to reflective strip
- CA1727 — 4,000-point memory; USB / TachoGraph; IP51
Typical applications
- Motor / fan RPM checks.
- Conveyor linear speed.
- Machine maintenance tach surveys.
Selection guide
