How the system works:
When not in use, Pods should be stored in an environment with an ambient temperature between 0°C and 30°C.
Sensor malfunction/failure can occur when Pods are exposed to condensing levels of humidity for an extended period of time.
1 Per sensor manufacturer datasheet: The humidity and temperature sensors are factory-calibrated and the calibration data is stored in the on-chip non-volatile memory. Please click here to view the sensor manufacturer’s data sheet.
2 Humidity Sensor Max Accuracy The humidity measurement accuracy specification is based upon testing performed on random samples of at least 2% of all manufactured units at an ISO 17025 certified calibration laboratory. At least 99% of all units manufactured will perform within the stated accuracy claims with more than 99% certainty.
3 Exact battery life can vary depending on device age, use case and operating temperature. Battery life will be inherently diminished when Pods are operated continuously at temperatures below 0°C.
4 “Typical” use of a Pod is considered to be actively logging for a total of 8-16 hours with one full log download per day, every day while operating at 0°C - 20°C.
Recommended Operating Range The recommended operating range for the data logger is 20% up to 80% RH (non-condensing) for temperatures of -10C to 60C. Operation outside of this range can result in a shift in sensor readings. Prolonged exposure outside of this range can result in extensions in Pod recovery time. Pods exposed to condensing levels of humidity for an extended period of time will likely result in electrical failure.
Hysteresis The RH sensor will experience hysteresis, and readings can vary based on the duration of time the sensor sat at the previous humidity level. This means that sensor readings can be dependent on whether the sensor is changing from a low-to-high vs. a high-to-low humidity environment. Any effects resulting from hysteresis should disappear after suitable soak times, allowing the sensor to stabilize. Typical effects of hysteresis (+1% RH) over the range of 20% to 80% RH are taken into consideration for the accuracy claim.
High Humidity Environments Exposure to high humidity (80% RH and above) can cause drift in sensor readings. Based on information from the sensor manufacturer, this drift could be up to 1.5% RH for short, non-condensing exposures. The sensor comes with a factory-fitted protective cover to help mitigate some of the effects from high humidity exposure. The observed drift can disappear slowly as the sensor is brought back to and operated under normal ambient conditions. The time required for the sensor to recover depends on the magnitude and duration of exposure to high humidity. Above 90% RH it is difficult to avoid condensation on the sensor, which will result in sensor errors. Additionally, prolonged exposure to high humidity may result in shifts in sensor readings that persist indefinitely.
Stated accuracy does not include:
- Effects from operation outside the recommended operating range, or long term exposure to very humid conditions.
- Contamination of the sensor by particulates, chemicals, etc.
- Other aging-related shifts (long-term stability).
