Vibration, Time & Speed

ATS, ATA, ATHA, ATHS Tachometers and Tach/Hourmeters

The AT series tachometer is a rugged, transistorised instrument with solid-state circuitry for indication of engine revolutions per minute (RPM). It is equipped with a bracket for mounting into a standard 86mm (3-3/8 in.) dash mounting hole.

The tachometer’s full 270° sweep of the pointer gives an accurate indication on a large easy–to–read scale. The dial can be illuminated for night reading.

ATA models sense engine speed in conjunction with an engine-driven charge alternator; ATS models work with a flywheel mounted magnetic pickup. ATHA and ATHS models are also equipped with a digital hourmeter to record the elapsed running time of an engine.

Features:

  • Sensing from magnetic sensor (ATS, ATHS) or
    battery charging alternator (ATA, ATHA)
  • High visibility 0-3000 or 0-4000 RPM analogue scales,
    270° sweep
  • 0 - 100,000 hourmeter, LCD (ATHA, ATHS models)
  • Reliable air-core movement
  • Easy calibration using DIP switches
  • Through-dial lighting
  • Universal 12/24 VDC (11-28 VDC) power supply, reverse polarity protected.
