Small distances, inaccessible by a micrometer screw gauge
Travelling microscope
Measure force
Small forces: newton meter or slotted masses and hanger
Larger forces: force meter
Temperature of small space(temp of a droplet of liquid/within a crack) or rapidly changing temperature
Thermocouple thermometer
Supply heat energy at constant rate to a fluid
Heater
Large tank of water with a constant temperature controlled by thermostat
Water bath with thermostat control
- temperature can be set to diff values
