Time Calibrators
Time Calibrators
SF2003 Time Calibrators are multi-function calibration instruments designing, developing and producing as per Verification Regulation of Time Calibrators (JJG 601-2022). It can calibrate mechanical/electronic stopwatch, 405/407/408/415/417 type electric stopwatch and 411 type millisecond meter.
Based on high accuracy OCXO as its internal time base, it outputs fully digitally controlled and stable calibration signal. 7 inch touch screen suitable for easy operation.
Standardly configured PC Software makes the remote controlling of SF2003 realized with ease.
Applications
Metrological Services
Used to calibrate stopwatches and timers to meet standard accuracy requirements, ensuring the reliability of time measurements.
Factories
Verifies the precision of timing devices used in production processes, maintaining consistency in manufacturing operations.
Academies and Research Institutions
Supports experiments and research that require accurate timing, providing calibrated tools for time-sensitive studies.
Sports Events
Ensures the accuracy of stopwatches used in competitions, guaranteeing fair results in timing-based sports.
Laboratories
Calibrates timers for scientific tests and experiments, where precise time measurement is critical for valid data collection.
During calibrating mechanical/electronic stopwatches, 4 measuring functions--Auto Measure, Single Measure, Cycle Measure, Batch Measure can be selected as per actual measuring requirement, which will highly improve working efficiency.
It can also calibrating 405/407/408/415/417 type electric stopwatch and 411 type millisecond meter.
With 7 inch touch screen, it is more convenient for instrument operation and matches the increasing market requirement to the display.
The standardly configured PC Software makes the automatic measurement and remote controlling easy, thus improve the measuring efficiency.
