Overview: This document provides technical specifications and features for two types of tachometers: the Contact Type Tachometer CT900 and the Laser Tachometer LT900. Both devices are designed to measure rotary and line speeds with additional functionalities such as real-time, maximum, minimum, and average measurements.
Contact Type Tachometer CT900:- Measurement Capabilities: Measures rotary speed from 0.5 to 19999 rpm and line speed from 0.05 to 1999.9 m/min.
- Resolution: 0.1 rpm for speeds below 1000 rpm and 1 rpm for speeds above 1000 rpm; 0.01 m/min for speeds below 100 m/min and 0.1 m/min for speeds above 100 m/min.
- Accuracy: ±(0.5%+d) rpm for speeds below 300 rpm and ±(0.05%+d) rpm for speeds above 300 rpm; ±(0.1%+d) m/min for line speed.
- Specifications: Sampling time is 0.8 seconds for speeds above 60 rpm. Powered by 2x1.5V AAA batteries. Dimensions are 55×33×158 mm, and it weighs 106g.
- Features: Includes a backlight for visibility and the ability to review the last measured value.
Laser Tachometer LT900:- Measurement Capabilities: Measures rotary speed from 2.5 to 99999 rpm.
- Resolution: 0.1 rpm for speeds below 1000 rpm and 1 rpm for speeds above 1000 rpm.
- Accuracy: ±(1%+5d) rpm, where d is the resolution.
- Specifications: Measuring distance ranges from 50 to 500 mm. Powered by 2x1.5V AAA batteries. Dimensions are 56×30×127 mm, and it weighs 106g.
- Features: Includes a backlight and the ability to review the last measured value.
Optional Accessories: Both tachometers come with optional accessories, including a wheel clamping sleeve and various cone attachments.
