AVAIN LABS® Contact+Non-Contact Combo Tachometer DT-2236C

Description

AVAIN LABS® Contact+Non-Contact Combo Tachometer DT-2236C

The AVAIN LABS® Contact + Non-Contact Combo Tachometer DT-2236C is a versatile digital instrument designed for accurate measurement of rotational speed (RPM) using both contact and non-contact methods. Its dual-mode design allows users to measure rotating machinery without physical contact using laser/photo detection, or directly measure rotational speed using the contact mode. The DT-2236C is suitable for industrial maintenance, mechanical engineering, laboratories, workshops, manufacturing, quality control, and educational applications.

With a non-contact measuring range of 2.5–99,999 RPM and a contact range of 5–19,999 RPM, the instrument provides a broad measurement capability for motors, shafts, fans, pumps, conveyors, engines, and other rotating equipment. Its memory function stores the last, maximum, and minimum RPM values for convenient comparison and inspection.

Contact & Non-Contact Measurement

The DT-2236C Combo Tachometer provides two measurement methods in one instrument.

Non-Contact / Laser Measurement:
The photo/laser mode allows rotational speed to be measured without physically touching the rotating object. This is particularly useful for fast-moving or difficult-to-access components and helps avoid interference with the rotating system.

Contact Measurement:
The contact mode allows direct RPM measurement using the appropriate contact accessories. This is useful where physical contact with the rotating shaft or surface is practical.

The combination of both methods makes the DT-2236C a flexible digital RPM meter and rotational speed measuring instrument.

Wide RPM Measuring Range

The instrument provides a wide speed measurement range:

• Non-Contact / Laser: 2.5–99,999 RPM
• Contact: 5–19,999 RPM

The high-speed non-contact range makes the tachometer suitable for a broad range of rotating equipment and industrial applications.

High-Resolution Measurement

The DT-2236C provides fine resolution at lower rotational speeds:

• 0.1 RPM from 2.5 to 999.9 RPM in non-contact mode
• 1 RPM above 1,000 RPM

The specified accuracy is ±0.05% + 1 digit, providing precise RPM measurement for inspection and maintenance applications.

Memory Function

The tachometer automatically stores important measurement values, including:

• Last RPM Value
• Maximum RPM Value
• Minimum RPM Value

This memory feature is useful for comparing operating speeds and identifying changes in rotational performance during inspection and maintenance.

Applications

The AVAIN LABS® DT-2236C Tachometer is suitable for measuring the rotational speed of:

• Electric Motors
• Engines
• Fans & Blowers
• Pumps
• Shafts
• Rotating Machinery
• Conveyors
• Industrial Equipment
• Mechanical Systems
• Laboratory Equipment
• Manufacturing Machinery
• Workshop Equipment

It is also useful for preventive maintenance, equipment inspection, quality control, research, engineering laboratories, and educational demonstrations.
