Displacement of a stainless steel plunger entering an exact mass of mercury is accurately measured by a micrometer screw. This operates a mechanical counter which reads the exact temperature of control. A secondary larger plunger sets the range of the instrument anywhere from -35° to 200°C in 100°C intervals. The counter covers 100°C in .02°C divisions, with readability to .01°C. G 2 1 0 2 0 Thermoregulator, ultra micro, filled with mercury and ready for use 0-100°C «170
