TemperatureDigital precision resistance sensor Pt100 up to 400 °C with resolution of 0.001 K as reference sensor,with ALMEMO® D7 connector for ALMEMO® v7 measuring devices / data logger Digital precision resistance sensor Pt100 FPD723L0250A3D For immersion measurements in air, gases and liquids Digital precision resistance sensor with highest accuracy and linearity for temperature measurements in a wide temperature range. Highest resolution 0.001 K over the entire measuring range. Application as reference probe for comparison measurements in research, development, quality assurance and production processes. For all ALMEMO® V7 measuring instruments/data loggers, ALMEMO® 202-S, 204, 104, 710, 510, 809. The digital ALMEMO® D7 measuring plug operates with its own built-in AD converter. The linearization of the Pt100 characteristic is calculated according to DIN IEC 751 (no approximation method). The overall accuracy of the measurement is independent of the ALMEMO® V7 display unit/data logger. The complete measuring chain, consisting of the Pt100 sensor and the connected ALMEMO® D7 measuring plug, can be calibrated. Highest accuracy is achieved during calibration by a multi-point adjustment of the temperature sensor. The digital sensor is supplied with a DAkkS accredited calibration certificate incl. multi-point adjustment. 11/2025 • We reserve the right to make technical changes.
