1529-R Chub-E4 Four-Channel PRT/Thermistor Thermometer Readout
Verified working. Calibration has expired.
Product Overview
This selection guide covers the Fluke Calibration family of industrial thermometer readouts and reference probes used together to calibrate PRTs, RTDs, thermistors, and thermocouples. The readouts profiled include the 1502A, 1504, 1523, 1524, 1529, and 1586A Super-DAQ, paired with reference probes from the 5615 Secondary Reference, 5627A Precision Industrial, 5628 Secondary Standard, 5606 Full Immersion, and 5610 Thermistor Secondary product lines. The guide presents a five-step method for matching a readout and reference probe to a specific calibration application: choosing the readout, selecting the reference probe by temperature range and immersion depth, determining combined system accuracy, verifying test accuracy ratio against the sensor under test, and evaluating whether additional calibration is required.
Industrial temperature sensors are typically calibrated by placing them in a stable temperature source — a dry-well, furnace, or calibration bath — and comparing their output to a reference standard probe connected to a thermometer readout. The guide is written for calibration laboratory and field applications that include improving calibration accuracy in a bath or dry-well, and comparing against process instrumentation in-situ such as a thermowell next to a gauge or transmitter. Selection criteria addressed include the sensor types to be calibrated, field versus laboratory use, channel count, data logging and graphing requirements, and whether temperature source control is needed to automate sensor calibration.
Beyond cataloging Fluke Calibration readouts and probes, ValueTronics carries this family of instruments in both new and pre-owned condition out of its 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. All inventory is stored, inspected, and tested in-house rather than drop-shipped from a third party, so the readout, the matching probe with the correct connector type, and any accessory cables can be staged and verified as a complete calibration system before shipment.
