Time Verification Instrument Standard Device

Time Calibration Instrument

Our fixture can place the stopwatch horizontally for testing, or vertically, whereas fixtures from other manufacturers can only test horizontally. If vertical testing is desired, they must rely on leaning against a wall or other objects, which may introduce certain deviations in the measured data. Moreover, their fixtures are crudely made. 2. Fixtures from other manufacturers can only test one stopwatch at a time, while our fixture can simultaneously measure multiple stopwatches, significantly saving time. Additionally, our fixture is more finely crafted and better complies with stopwatch verification regulations.

Product Introduction

The GDS-50 Stopwatch Calibrator is a high-precision time calibration instrument. This device is a multifunctional, comprehensive automatic testing apparatus for time calibration, developed in accordance with the requirements of JJG237-2010 "Verification Regulation for Stopwatches." It is used to calibrate mechanical stopwatches, electronic stopwatches, pointer-type electric stopwatches, digital electric stopwatches, digital millisecond meters, and various other timers. The instrument under test measures the standard time interval signal, obtaining the actual measured value of the standard time interval signal, thereby determining the measurement error of the instrument under test and achieving the purpose of calibration. It is suitable for value transfer of various types of stopwatches, can establish a standard device for stopwatch calibrators, and carry out verification/calibration of time-related instruments.

Product Function

It can be used by metrology departments at all levels, factories, universities, and research institutions to calibrate time instruments such as 401/405 electric stopwatches, 407/408 electric stopwatches, 411 digital millisecond meters, and 415/417/417B digital electric stopwatches.

Product Features

a) High precision and cost-effectiveness;

b) Comprehensive functions and reliable performance;

c) Utilizes a highly stable quartz crystal oscillator as the time base.

Typical Applications

1) For metrology departments, factories, universities, and research institutions to calibrate timing instruments such as mechanical stopwatches, electronic stopwatches, pointer-type electric stopwatches, digital electric stopwatches, and digital millisecond meters.

2) Used as a daily difference measuring instrument;

3) Used as a standard time interval generator;
