ondyne 2000-A-N-NV hygrometer with probe

The Ondyne 2000‑A‑N‑NV is a precision industrial hygrometer that uses a detachable probe to measure relative humidity in process environments. Common failure modes for this class of devices include probe corrosion or contamination, drift in the internal temperature sensor, and degradation of the analog-to-digital converter circuitry due to long-term exposure to high moisture levels. First‑check diagnostics: verify power supply voltage and polarity at the unit’s input; inspect the probe connector for loose contacts or visible damage; review any error codes displayed on the LCD or transmitted via serial interface for indications of sensor or calibration faults.[oss-gpt-20b] Post Comment
