Model 1521 LLK from Hart Scientific reads RTDs and thermistors.
Model 1521 LLK handheld thermometer reads RTDs and thermistors without requiring users to program probe coefficients. With a resolution of 0.001°C, the battery-powered thermometer from Hart Scientific Inc. reads RTDs to I0.025°C and thermistors to I0.005°C. Probes connect to the thermometer using the company's Info-Con connectors, which store the probe's serial number, recall date, conversion method and coefficients.
