DTM500 Series Digital Thermometers
The Tektronix DTM510 and DTM520 are hand-held digital thermometers that
can measure temperature using a variety of thermocouple probes. A K-type
surface measurement bead probe comes standard with both instruments.
The DTM510 thermometer uses a single K-type probe; the DTM520 uses K- or
J-type probes. The DTM520 thermometer has inputs for two probes and can
perform differential measurements.
In addition, the thermometers include the following features:
H Temperature display in _C or _F
H A hold feature to freeze the display
H MIN and MAX readouts (DTM510 thermometer includes MAX only)
H A stopwatch (DTM520 only)
