QWA-5A Quartz Clock and Watch Tester
Product Overview
The QWA-5A Quartz Clock and Watch Tester is a precision measurement instrument widely used in the quartz clock and watch industry. It is primarily designed to measure the frequency accuracy of quartz crystals used in clocks and watches and to evaluate the timekeeping accuracy of various quartz clocks, watches and electronic devices.
The QWA-5A can measure daily error, monthly error and ppm-level frequency deviation of quartz clocks, watches and quartz crystals. Its probe-type accessory is suitable for testing a wide variety of finished and semi-finished products.
With high reliability and stability, the QWA-5A is designed for demanding production environments. It can maintain stability within 0.5 ppm over a relatively wide ambient temperature range, making it suitable for precision quality control and production testing.

Key Features
• Designed specifically for precision testing in the quartz clock and watch industry
• Measures quartz crystal frequency accuracy
• Measures timekeeping accuracy of quartz clocks and watches
• Supports daily error measurement
• Supports monthly error measurement
• Displays clock, watch and crystal frequency deviation in ppm
• Probe-type accessory suitable for finished and semi-finished product testing
• High reliability and excellent long-term stability
• Maintains stability within 0.5 ppm over a wide ambient temperature range
• Suitable for production environments and quality control applications
• Compact design for convenient installation and operation

Working Principle
The QWA-5A evaluates the frequency accuracy and timekeeping performance of quartz-controlled clocks, watches and electronic devices by measuring their timing or oscillation frequency deviation from the reference standard.
During testing, the probe accessory can be connected to or positioned at the appropriate measurement point of the finished or semi-finished product. The instrument detects the frequency deviation and calculates the corresponding timekeeping error.
Measurement results can be expressed in ppm, while clock and watch performance can also be evaluated through daily error and monthly error, providing a convenient method for production inspection and quality control.
