China Astronomical Clock:

Astronomical Clock is a kind of high precision time measuring instrument, the vibration frequency of the frequency of 4.19 MHz AT cut circular frequency of quartz crystal as a time reference, using the temperature frequency capacitor automatic compensation, can guarantee in a wide temperature range with highaccuracy of the clock. The time indication way for the second jump threeneedle analog, this product adopts two No. 1 batteries in parallel type power supply, so as to improve reliability, but also can replace the batteryconveniently, the quartz clock in the replacement of the battery does not stop and go, the other two batteries power supply also prolong the service life of the battery.

This product is with high second signal stability, in addition to poking mechanism of foreign, also with the speed, the stop button and other devices,the product is suitable to use in navigation, astronomy, seismic, geodetic and laboratory as time standard.

Specifications:

1. Oscillator: NDK 4.194304MHz

2. Time Keeping Accuracy:≤±0.2s/day at +20℃±1℃

3. Power: DC 1.5V

4. Second Movement Type:Leapfrog

5. Resistance to vibration and Impact Performance:(The clock should run normally at following conditions)

1) Vibration Frequency:80Hz, Acceleration:2g

2) Impact Acceleration:7g, Impact Frequency: 60~80 times per minute.(The clock should run normally with 2000 times impact.)

6. Antimagnetic Performance:≥7 oster

7.Size: 200×145×80mm, Weight: ≤3kgs
