STM-Rb-H Ultra-High Performance Rubidium Clock

The STM-Rb-H rubidium clock utilizes exclusive slotted resonator cavities and independent temperature control for triple vapor cells, significantly enhancing the performance of the rubidium atomic clock. This atomic clock exhibits excellent frequency stability and aging rate under both ambient temperature and vacuum conditions. With a smaller size and lower power consumption, the clock's frequency stability is comparable to that of passive hydrogen masers. This product can be used in metrology, timekeeping, aerospace, military, and other fields.
