The advantage of TSL vacuum tube
High efficient temperature:adopting the advanced coating
technology,the amount that light converted into heat is
10% higher
than the normal vacuum tubes.
Endure the coldest temperature:
adopting the advanced
coating technology,the vacuum degree can
reach 5*10-4Pa,
then reduce the convection heat emission,at the
same time
the infrared reflector layer reduces the radiant emission
enable the tubes can work well in the coldest temperature
area.
stable function:It has long longevity,Going through36 working
procedures ensure the coating stbilization and
withstand
attenuation.
