CT6/M/K Standard Optical-Contact Tachometer (Metric) & VLS5/J Remote Sensor



The Concorde CT6 and CT6/LSR Optical-Contact Handheld tachometers are available in a variety of models to suit most applications, with large Bright LED displays and a wide selection of excellent features, including standard optical system range up to 1 metre or with a Laser system with a range up to 2 metres for enhanced optical performance, these handheld Tachometers have facilities for both Optical and Contact measurements.

Standard Optical System

  • Optical Range (50mm – 1000mm)
  • Optical Angle (± 45° degree)


  • Bright LED Display
  • Very wide speed range
  • Long Optical Range
  • Last reading hold and recall memory
  • Additional Count and Times modes
  • Range of contact adaptors for rpm and linear rate
  • External input for remote optical sensors is standard
  • Wide range of accessories

Measurement Ranges

  • RPM
  • Linear speed Metres and Feet per minute (Metres/Seconds – Metric Model)
  • Count mode – length and revolutions
  • Time interval (Reciprocal speed)
  • Time accumulative (Average rate)

Metric only versions are available with two Linear ranges, Metres/Minutes and Metres/Seconds.

Maximum speed with Contact Adaptor: Governed by upper speed limit of bearings and is affected by measurement duration, typically 50,000 rpm for 10 Seconds. Maximum linear rate is typically 1,500 metres/minute or 4,500 feet/minute.
