Fluke HART 1521 Thermometer
With the Super-Thermometer, Black Stack, and Tweener thermometers, Hart established itself as the clear product leader for thermometer readouts. Our pattern of offering more power and more versatility for less money is indisputable. Now we underline that fact by introducing the two most powerful handheld thermometers in the world.
With the Super-Thermometer, Black Stack, and Tweener thermometers, Hart established itself as the clear product leader for thermometer readouts. Our pattern of offering more power and more versatility for less money is indisputable. Now we underline that fact by introducing the two most powerful handheld thermometers in the world.
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.
When you connect your probe, the 1521 automatically recognizes whether you’re using an RTD or thermistor and downloads the calibration constants and type of conversion specific to your probe. It also checks the recall date stored in the INFO-CON to verify it has not expired. To dedicate a single probe to your readout, disable the password-protected interchangeability function and your thermometer will read only the probe you specify.
Forget entering calibration constants yourself, and don’t worry about the mistakes that can so easily occur during that process. You don’t even need to select your sensor type. It’s all stored in the INFO-CON. Simply plug in your probe and you’re ready to take readings. It doesn’t get any easier.
Information is loaded into the memory of the INFO-CON by Hart when you purchase a probe or have a probe recalibrated by Hart. Alternatively, you may load your own information into an INFO-CON through the Handheld Thermometer or from the serial port of your PC with the optional download adapter. The adapter includes Model 9972 software, which provides an easy-to-use Windows interface to guide you through the loading process.
If you’d like to use a Hart Handheld Thermometer with probes you already own, no problem! Spare connectors are available. They connect easily to your probes, and you can program them yourself.
Model 1521 LLK
The 1521 uses a menu system for convenient access to all functions. Calibration and sensor programming functions are password protected to help prevent unauthorized access.
“Min” and “Max” functions store the lowest and highest readings since the last reset. The “Hold” function freezes and stores the current reading (up to six may be stored) for later recall. And the “Delta” function computes the difference between the current reading and a reference value, which may be recorded at any time.
Each thermometer comes complete with rechargeable nickel-metal-hydride batteries, an AC adapter/charger, an RS- 232 cable for connecting to your PC, and a spare INFO-CON connector. Every unit also includes a NIST-traceable calibration with actual resistance measurements for your individual meter at 10 points—4 representing typical RTD values and 6 representing typical thermistor values.
A wide variety of standards-quality probes are available from Hart in many different shapes, sizes, and price ranges. On pages 64 to 75 you’ll find PRTs as accurate as ±0.010°C and thermistors as accurate as ±0.001°C. The uncertainty of your probe should be added to the uncertainty of the meter to compute total system uncertainty.
