Fluke Thermometer Models

Fluke Thermometers for Calibration Referencing

Fluke Thermometers are ideal for calibration referencing, the Fluke 1523 and Fluke 1524 measure, graph, and record PRTs, thermocouples, and thermistors; the handheld tools deliver exceptional accuracy and wide measurement ranges.

These versatile Fluke Thermometer instruments can be taken anywhere. The Fluke 1523 and Fluke 1524 models let you handle field applications with ease, as well as typical laboratory measurements and data logging too. With dual channel measurement capabilities of both models, the Fluke Thermometer range can do twice the work in half the time.

Reference Thermometers by Fluke are designed for accuracy, precision, and compliance with the latest safety standards. The Fluke 1523 and Fluke 1524 both deploy current reversal, a technique used in high-end instruments, to eliminate thermal EMFs (electromagnetic forces) for precision temperature measurements.

Specifications are guaranteed from –10 °C to 60 °C ambient. Special precision resistors and a highly stable reference voltage source keep accuracy virtually insensitive to environmental temperature. Like all Fluke thermometers which are handheld, the 1523 and 1524 Reference Thermometers come with a two-year warranty and free lifetime technical support.

Choosing the right probe:

Probes for Fluke 1524 and Fluke 1523

It is important to select a reference probe that covers the full temperature range requirements of the sensor application.

We have a number of probes available all offering different benefits to the user. Of these Fluke probes, there are 5 key probe types that are compatible with the Fluke Thermometer, those being:

Standard reference PRT

Precision industrial PRT

Secondary standard PRT

Full immersion PRT

Thermistor secondary probe

We have a table below that highlights the key data such as probe range and accuracy. The table should help in deciding the correct probe for your application, however, if you need some additional assistance then get in touch and one of our technical sales team will be happy to help select the correct probe for your requirements.
