Finely divided particles preferably formed into tablets or into pellets of granular temperature indication material are used as a thermometer and are brought into contact with a surface to measure surface temperature by a change in appearance of the indication material at a known temperature. The handle assembly may define a proximal and distal end such that, in use, the proximal end is further away from the hard disk drive being assembled than is the distal end. The movable exhaust pipe includes one or more interference tabs concentrically and circumferentially fitted about its exterior surface. The equalizer is switched to use the MMA when the cost reaches a first threshold.
