Fluke 1524 Reference Thermometer
Finally, a reference thermometer as versatile as you are
The new 1524 Reference Thermometer from Flukeﾒs Hart Scientific division measures, graphs, and records PRTs, thermocouples, and thermistors. The new thermometer readouts deliver high accuracy, wide measurement range, logging, and trending, all in a handheld tool you can take anywhere.
The 1524 lets you handle field applications, laboratory measurements, and data logging with ease. And with the dual channel measurement capabilities of the model 1524, you can do twice the work in half the time.
Make accurate, consistent measurement…anywhere
You need accuracy for compliance, product yields, energy savings, and consistent results. The 1524 uses current reversal, a technique used in high-end instruments that eliminates thermal EMFs, for precision temperature measurements. Specifications are guaranteed from ﾖ10 °C to 60 °C ambient. Special precision resistors and a highly stable reference voltage source keep 1524 accuracy virtually insensitive to environmental temperature.
Like all Fluke handheld tools, the 1524 Reference Thermometer endures rigorous testing in temperature extremes and under harsh conditions of vibration, so you can take it with confidence anywhere you need to go.
Monitor trends in the lab or in the field
See trends graphically on the 1524 thermometerﾒs 128×64-backlit LCD display. You can change the graphﾒs resolution at the touch of a button. Now it is easy to see when the temperature is stable (without statistics or long delays) or to monitor processes over time to verify correct operation.
Hold readings on the display at the touch of a button, or document up to 25 readings and associated statistics for easy retrieval. Statistics include the average maximum and minimum values, and the standard deviation.
View them through the display or by uploading it to a PC via RS-232 conection and 9940 I/O TookKit software, included free. To monitor and log more data over time, use a PC and optional LogWare II software
RS-232-to-USB adapters are available for those who prefer USB connectors. Battery power lasts at least 20 hours on three AA batteries, or use the dc power adapter for extended periods of measurement. Power saving features can be enabled or disabled for longer battery life or greater convenience.
INFO-CON connectors ensure correct temperature conversion
Inside the INFO-CON, a memory chip keeps calibration information for the attached probe. Simply plugging in the probe uploads the information to the readout. The connector transfers this information to the 1524 automatically, ensuring the correct temperature conversion for accurate, hassle-free measurements
Probes may be locked by password to specific channels and readouts for security or for system calibration traceability. Plug any thermocouple with mini-thermocouple jacks into an optional universal thermocouple adapter for convenient measurement. Each thermocouple adapter or standard connector supports reference junction compensation (RJC) with its own internal precision thermistor.
Features:
High accuracy
PRTs: up to ± 0.011 °C
Thermocouples: up to ± 0.24 °C
Precision thermistors: ± 0.002 °C

Fitting easily into your hand and weighing only 1 pound (0.4 kg), these thermometers can go anywhere. And when they get there, you can have total confidence in the accuracy of your measurements. The 1522 has the power of a full data logger, with memory to hold 10,000 readings.

Probes
The 1521 and 1522 read both Pt-25 and Pt-100 RTDs as well as thermistors. PRTs and RTDs, with their wide temperature ranges and stabilities, have long been favored as temperature standards. From –200°C to 100°C, the 1521 reads PRTs accurately to ±0.025°C. Even at 800°C these are high-precision readouts, accurate to ±0.1°C.
Ultra-stable thermistors offer excellent stability and even greater accuracies over a more narrow range—typically from about –10°C to 110°C. At temperatures below 50°C, these Handheld Thermometers read thermistors to ±0.005°C. Accuracy at 100°C is ±0.02°C.
While a small number of handheld thermometers on the market offer 0.01° resolution, they fail to provide the accuracy necessary for the last digit to be meaningful. Hart’s Handheld Thermometers let you select resolution from 0.1° to 0.001° and offer the accuracy to support even 0.001° resolution.
Of course, the 1521 and 1522 let you match the exact resistance versus temperature characteristics of an individually calibrated probe. This is true standards thermometry. Hart’s Handheld Thermometers read ITS-90, CallendarVan Dusen, or Steinhart-Hart coefficients for maximum system accuracy.
These are real algorithms, not approximating conversion methods or electronic look-up tables. If you want to use common industrial curves, RTDs can be read using the common DIN 43760 (IEC 751) curve and thermistors can be read using the YSI 400 curve.
INFO-CON Connectors
Probes attach to the 1521 and 1522 using Hart’s new “INFO-CON” connector. The INFO-CON (partially based on U.S. Patent 5,857,777) allows you to change the probes you use without requiring you to reprogram your readout. A memory chip in the INFO-CON stores all the critical information about your probe, including its serial number, recall date, and calibration constants.
