Digi-Stem Meters & Probes are sold separately and paired together to create a complete custom system. This listing is for the probe only.
Digi-Stem® meters and probes are sold separately for a completely customizable system. Pair your Digi-Stem® DST620/DST660 Series Meter with an adjustable angle, straight or angle rigid, or remote probe to meet the requirements of your installation. DST620 & 660 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 secondary sensors via 1/2 inch NPT Female connector on the side of the housing.
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.
DST620 & 660 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 DST620 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® DST620 & 660 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.
