Digi-Stem® meters and probes are sold separately for a completely customizable system. Pair your Digi-Stem® DST621/DST661 Series Meter with an adjustable angle, straight or angle rigid, or remote probe to meet the requirements of your installation. DST621 & 661 probes utilize ten conductor cables for dual sensor remote probes, and are available with IP68 rated quick disconnect connector options on the meter and/or probe side. Note that the secondary RTD is entirely independent, powered by customer provided 24VDC loop power. The primary RTD sensor, LCD screen, and meter electronics are powered by the internal battery, and comprise the "TID" (temperature indicating device.) Access the secondary RTD via four-pin Turck® brand connector on the side of case for a watertight access to the transmitter.
Use the quick disconnect option to disconnect the meter and probe for lab calibration, while leaving the cable in place for easy removal and replacement.
DST621 & 661 Series probes feature our unique Probe ID feature available on rigid probes and remote probes with a cable length of 25 meters or less. Probe ID prevents the connection of unauthorized probes to your DST621/DST661 meter; using an unauthorized probe will display a "Prb" error on the LCD screen. If you don't want Probe ID, please ask for it to be disabled when ordering.
Digi-Stem® DST621 & 661 Series probes utilize Pt100, Class A, 4 wire platinum RTD sensors in MgO packed MI cable. Programmable RØ allows any initial tiny probe error to be offset in the meter. Sanitary probes are in compliance with 3A Standard 74-06.
To build your probe, refer to our probe configuration matrix. Choose one option from each section to build a standard probe configuration.
NIST Traceable Certificate of conformance is available.
