In laboratory environmental testing, substandard humidity levels in constant temperature and humidity chambers are a common problem, often stemming from three easily overlooked hidden settings. By dissecting these three core settings, you can quickly resolve humidity issues.

Constant Temperature and Humidity Incubator—Three Hidden Settings You Shouldn't Overlook:

1. Humidity PID Parameter Calibration:

Most users default to the equipment's factory settings, neglecting the fact that environmental temperature differences and sample characteristics can affect parameter adaptability. Users can press and hold the "SET" button on the control panel for 5 seconds to enter calibration mode, fine-tuning the proportional, integral, and derivative parameters according to actual testing needs to avoid humidity overshoot or lag.

2. Humidification System Mode Switching:

Many users use the default humidification mode for extended periods, unaware that the equipment features an external isolated humidification system with "rapid humidification" and "stable humidification" modes. Switching to the corresponding mode can prevent fluctuating humidity levels, reduce scale buildup in the humidification tubes, and extend component lifespan.

3. Sensor Segment Calibration:

Humidity sensors are prone to dust accumulation and shifting over time, leading to distorted data. Users can periodically wipe the sensor probe with a dry cloth, access the calibration interface through the control panel, and fine-tune using a high-precision portable thermometer and hygrometer to ensure accurate detection.
