Descripción detallada
El HC2S3 incluye un filtro de polietileno que protege el sensor del polvo fino y partículas, minimizando la absorción y retención de agua. Opcionalmente está disponible un filtro de teflon adecuado para ambientes marinos. El tiempo de respuesta es más lento si se utiliza el filtro de teflon.

Campbell Scientific offers two filter tips:
- The HC2S3-L comes with a polyethylene filter that provides protection against fine dust particles, doesn't absorb or retain water, and offers a good response time.
- A Teflon filter can be ordered separately (pn 27755, HC2S3 Replacement Teflon Filter). This filter has a smaller pore size (10 micron) that provides good protection against fine dust particles and salt (marine environments), but it has a slightly slower response time than the polyethylene filter.
-
The sensor should not be cleaned with water. If the sensor is dirty, the filter should be changed or cleaned more frequently. A dirty filter can be cleaned with distilled water.

To measure ambient temperature and relative humidity (RH), mount the HC2S3-L probe inside a 41003-5 or 41003-5A 10-Plate Radiation Shield. The 27731 hex plug is shipped with the HC2S3-L so that it can be used with older 10-plate radiation shield models. The 6-plate radiation shield (pn 41303-5A) cannot be used with the HC2S3-L.

Note the difference between calibration and a field check. Calibration cannot be done in the field, as it requires an experienced technician and specialized equipment.
Field checks of measurements can be done to determine if the data make sense with the real-world conditions. Follow these steps to field check a sensor:
- Find a second sensor of the same type as the installed sensor whose data is in question. The second sensor will be used as a benchmark sensor and should be known to be accurate or recently calibrated.
- At the site, take readings using both sensors under the same conditions. The best practice is to measure both sensors side-by-side at the same time. Note that the sensors will never have the exact same measurement.
- Depending on the sensor model, if the difference in the readings of the installed and benchmark sensors is greater than the sum of the accuracies for both sensors, either return the installed sensor to Campbell Scientific for calibration or replace the appropriate chip.
- The 107, 108, 109, 110PV-L, and BlackGlobe-L temperature sensors can be calibrated.
- The HC2S3-L and HMP155A-L temperature and relative humidity sensors can be calibrated.
- The CS215-L has a replaceable chip for temperature and relative humidity. For more information, refer to the “Maintenance and Calibration” section of the CS215 instruction manual.
- The HMP60-L has a replaceable chip for relative humidity only. For more information, refer to the “Maintenance” section of the HMP60 instruction manual.

To incorporate a sensor that is compatible with wireless sensor interfaces into a wireless network, a CWS900-series wireless sensor interface is needed, as well as an A205 CWS-to-PC interface to configure it.
