DT-6234B Photo Tachometer, Non-Contact RPM

The DT-6234B is a non-contact LED photoelectric tachometer for reading rotational speed from a reflective mark. It covers 2.5~99,999 RPM at ±(0.05%+1) and adds a cumulative count function (1~99999) for counting revolutions or items. It runs on 4×AA batteries or an external DC 6V supply, which suits bench testing and longer sessions at a production line.

Key features

• LED photoelectric, 2.5~99,999 RPM
• Cumulative count 1~99999
• 4×AA batteries or external DC 6V supply
• Accuracy ±(0.05%+1), auto ranging, 99999 max display
• Resolution 0.1 RPM below 1000 RPM, 1 RPM above
• Max/Min/Last value memory; sampling 0.8s above 60 RPM

Applications

Speed checks on motors, engines, fans, pumps and speed control devices, and RPM set-up during maintenance of vehicles, ships, aircraft, model aircraft and production machinery.

Choosing within the series

In the DT-62 series, the DT-6234B is LED photoelectric, the DT-6234C is laser with 50~500mm range, the DT-6235B is contact only with surface speed and length, and the DT-6236B and DT-6236C combine contact with photoelectric or laser measurement. DT-6235B, DT-6236B and DT-6236C store 96 data sets; DT-6234B/C keep Max/Min/Last. Every DT-62 model accepts an external power supply as well as 4×AA batteries. The DT-22 series is the battery-only equivalent.
