DIGITAL DIFFERENTIAL THERMOMETERS

The Serviceman today needs an instrument that is reliable, durable and accurate,

has usable functions and probes for measuring refrigeration and air-conditioning

systems, and is reasonably priced. The Weiss DT51A and DT52A offer such a

product for temperature measurement.

The DT51A-1 is a type K thermocouple based single probe thermometer

with a range of -50/1999°F, resolution switch(0.1°F or 1°F), Data Hold feature,

Max Memory, °F or °C switch and includes a general use probe. The DT52A-4

is also type K thermocouplewith two probe inputs that offer the differential feature

required in refrigerationand air-conditioning service. Includes two velcro probes with

the sensor built in, plus a bead probe and general probe with handle in an ABS carrying case.
