Detailed Product Description

The ST926 Digital Tachometer (Non-Contact) is a handheld laser RPM meter designed for maintenance personnel, engineers, and technicians who require a quick and reliable method of measuring the rotational speed of moving machinery. By using photoelectric sensing technology together with reflective tape, the instrument accurately detects the speed of rotating shafts without requiring physical contact, reducing both equipment wear and operator risk.

Unlike contact tachometers, the ST926 allows measurements to be taken from a distance of 50 to 500 mm, making it especially suitable for equipment operating at high speed or in locations where direct contact is impractical. This non-contact measuring method helps improve safety while minimising the risk of interfering with normal machine operation.

With a wide measuring range of 10 to 99,999 RPM, the ST926 can be used on a broad variety of equipment, from slow-speed conveyor rollers to high-speed electric motors, fans, pumps, and other industrial rotating machinery. Automatic range selection enables fast measurements without manual adjustment, while the large LCD display provides clear and easy-to-read results.

For maintenance and troubleshooting, the built-in memory function stores the maximum, minimum, and last measured values, allowing users to compare readings and identify changes in equipment performance over time. Combined with its lightweight handheld design, automatic power-off function, and simple operation, the ST926 is an ideal tool for routine inspections, preventive maintenance programmes, equipment commissioning, and machinery diagnostics across manufacturing plants, workshops, HVAC systems, and industrial facilities.

Frequently Asked Questions

1. What is the ST926 Digital Tachometer used for?

The ST926 is designed to measure the rotational speed (RPM) of rotating machinery without making physical contact. It is commonly used for maintenance, equipment inspection, and troubleshooting.

2. How does the ST926 measure RPM?

The tachometer uses photoelectric sensing technology. A piece of reflective tape is attached to the rotating object, and the instrument detects each pass of the reflective mark using its laser sensor to calculate the rotational speed.

3. What types of equipment can be measured?

The ST926 is suitable for measuring the RPM of electric motors, industrial fans, pumps, compressors, conveyor rollers, generators, and many other rotating machines.

4. Is the ST926 a contact or non-contact tachometer?

The ST926 is a non-contact tachometer. It measures rotational speed from a distance without touching the rotating equipment.

5. Why is reflective tape required?

Reflective tape provides a clear target for the photoelectric sensor, enabling the instrument to detect each rotation accurately.

6. What is the measuring distance?

The recommended measuring distance is 50 to 500 mm from the reflective target.

7. Does the ST926 store measurement results?

Yes. It automatically stores the maximum, minimum, and last measured value for convenient review.

8. Does the ST926 automatically switch off?

Yes. To help conserve battery power, the instrument automatically powers off after approximately 15 minutes of inactivity.

9. Is the ST926 suitable for industrial maintenance?

Yes. Its wide measuring range, high accuracy, and non-contact operation make it ideal for preventive maintenance, machinery servicing, and industrial inspections.

10. What is the difference between a contact and non-contact tachometer?

A non-contact tachometer measures rotational speed using a laser sensor and reflective tape without touching the equipment, making it safer for high-speed or difficult-to-access machinery. Contact tachometers require direct contact with the rotating shaft, making them more suitable for applications where contact is practical and safe.
