Product Overview: PIECAL 311 Evolution Line RTD Calibrator

The PIECAL 311 Evolution Line RTD Calibrator makes temperature calibration faster, easier, and more accurate. With its intuitive EZ-CHECK switch, you can instantly select up to three preset outputs, while the two-speed EZ-DIAL knob and automatic stepping functions streamline calibration workflows. The bright backlit display ensures visibility in dark environments, and the secondary Ω display lets you verify RTD readings directly against standard tables. Compared to older models like the Altek 311, the PIECAL 311 offers higher accuracy at low excitation currents, enhanced durability, and improved compatibility with modern smart instrumentation. Its separate battery compartment preserves calibration seals and allows quick power changes without tools.
