  » CelsiStrips serve as temperature sentinels
  CelsiStrip self-adhesive labels are easily applied to any cleaned surface and will permanently change their specific temperature-indicating areas from white to black whenever specific temperature levels are reached or exceeded.
  These labels come in various arrangements of 40 sequenced temperature levels from +40° C/105° F up to 260° C/550° F. Applications include control of storage temperatures, to monitoring minimum and maximum temperature levels of thermal processes.
  Free samples are available from SAT (Spirig Advanced Technologies Inc), 144 Oakland St, Springfield MA 01108.
