What is the recommended calibration frequency for the E+E Elektronik HTP501 probe

[AriannaFitz]

To maintain optimal accuracy with your E+E Elektronik HTP501 Digital Humidity and Temperature Probe, calibration is recommended. While the probe requires no special maintenance, for the best results, especially when measuring across broad humidity and temperature spans, calibrate the probe every 12 months. You have options for calibration, including using a humidity calibrator, a handheld device, or humidity standards. Alternatively, you can send your probe to the E+E Elektronik calibration laboratory for professional calibration and adjustment. For detailed guidance on calibration and adjustment procedures, please consult the E+E Elektronik website or contact their customer support team.
