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 alsotype K thermocouple with two probe inputs that offer the differential feature required in refrigeration and 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.
Temperature indication follows National Bureau of Standards and IEC58 temperature/voltage tables for type K thermocouples which are supplied with the thermometer.
