heletimers
Heletimers are a class of timing devices designed for operation in helium-rich or cryogenic environments. The term is not standardized and can refer to several distinct implementations used in laboratories, manufacturing, and experimental setups. In general, heletimers aim to deliver reliable timekeeping or event triggering when conventional electronics face low temperatures, high purity gas handling, or restricted convection.
Common designs combine mechanical or electronic timing with a helium-compatible enclosure. Some implementations use sealed, low-outgassing
Typical applications include timing sequences in cryogenic experiments, helium-leak testing, and processes that use helium purge
Variants range from handheld, battery-powered units for field use to bench-top timers integrated into test rigs.
