MT25 Optical Tachometer and Stroboscope Calibrator
Important Note:
The MT2013 has been discontinued and is being replaced by the MT25. Any details shown below refer to the current MT25 model.
The MT25 is an optical tachometer and stroboscope calibrator built for day-to-day checking and calibration of optical tachometers, optical speed sensors and stroboscopes. It follows the same operating approach as the earlier MT2013, but in a refreshed enclosure with updated low-voltage electronics and a universal external power supply (included)—so there’s no need for region-specific versions.
As well as supporting most brands of optical tachometer and sensor, the MT25 can also be used with pulse-driven instruments such as digital panel tachometers, ratemeters, batch counters and similar devices.
Please note: the MT25 is intended to confirm tachometer accuracy. If you need to verify that a tachometer will work reliably at a specified distance from a target, a separate test unit is required. This equipment is Class I and must be earthed.
Key Features:
- Wide pulse-rate capability: supports very low to high input rates (using divider/scaling functions)
- Clear 5-digit LED readout: designed for fast, confident checks on the bench
- Flexible scaling and display options: scaling up to five digits with selectable revolution display modes
- Low-speed performance: suitable for very slow rotational checks (down to thousandths of a revolution)
- Strobe calibration support: variable strobe/VLS output across multiple ranges
- Multiple output choices: pulse output plus optional serial/analogue variants depending on requirement
- Traceable calibration: supplied with a calibration certificate
Key Benefits:
- Reduces downtime: quick verification of tachometers and optical sensors without sending instruments away
- Works across mixed fleets: suitable for checking “non-Compact” optical tachometers and stroboscopes as well as Compact models
- Consistent results: stable update behaviour and over-range indication aid repeatable checks
- Simple global deployment: one model for multiple regions thanks to the included universal PSU
