Digital RTD Thermometers Boast High Accuracy
Operating over a temperature range from -328°C to 1,472°F (-200°C to 800°C), Wahl Instruments’ DST500 temperature indicator, and DSX500 transmitter thermometers present total system accuracy of ±0.3°F (±0.2°C) over a 1-year period. The devices offer a 1"-high LCD display and standard and custom-built probe configurations, including MIG standard tapered bulb for drop-in direct MIG replacement. The “Unique Quick Disconnect” option allows the user to remove the probe and meter for calibration without removing the permanently installed cable, and the “Adjustable Angle” probe option enables display adjustment. The DST500 includes a field-replaceable battery with a 2-year operational life, while the DSX500 is loop powered from an integral 4-mA-to-20-mA transmitter for data transmission. The units are factory configurable to the user’s specification or user-configurable via the optional DSTPROG software kit.
