with an Aluminum Top, Serial No. 991000532150
Manufactures Comments/Specifications:
The 720 series hot plates are simple, direct entry, non-programmable
models, which allow the operator to set one temperature and one
timed period. Using a microprocessor to regulate key process
parameters - heating and ramp cycle timing, the 730 series hot plates
PMC 720 and 730 series digital hot plates are available with
aluminum and porcelain-coated stainless steel top plates. Aluminum
top plates heat quickly and uniformly. Porcelain-coated stainless steel
top plates heat-up more slowly than aluminum tops, but are more
