A2108 Optical/Contact Tachometer Probes
 
This Series of Speed Probes is available in three versions, the basic Multimeter Probe and two Data Collection models.

A2108 Multimeter TachoProbe
The Multimeter Probe will convert any Digital Multimeter into an accurate Optical Tachometer quickly and easily. This Probe measures rpm Optically or by using the optionally available Contact Adaptor, contact rpm & linear rate in Metres/minute only can be measured. The A2108 is an ideal instrument for economic general purpose rpm checking with a more than adequate specification via any Digital or Analogue Multimeter.

DataProbes - Data Collection Laser models - A2108/LSR and A2108/LSR/232
Two Laser versions are available, Model A2108/LSR with Analogue output (can also be used with a Multimeter) and Model A2108/LSR/232 with RS232 Output. Both models incorporate standard tripod mounting and very high speed response time (once per revolution) providing a sophisticated speed monitoring tool where rapid data collection is important.

Key features - DataProbe versions · All models include a continuous "hands free" measurement mode.

· Rapid response update - once per rev up to 60,000rpm (1 millisecond)
· Continuous measurement mode provides "Hands Free" operation
· Tripod mounting bush fitted as standard
· Contact measurement facility via optionally available Contact Adaptor
· Auto-zero feature
