Overview
The HC2S3-QD is a rugged, accurate temperature and humidity probe that is ideal for long-term, unattended applications. The probe uses an advanced capacitive sensor to measure relative humidity. The probe includes a filter to protect the sensor from dust and particles, for superior performance and reliability.
Key Advantages
Wired for RAWS-F Station
Technical Description
The HC2S3-QD comes with a polyethylene filter that protects its sensor from fine dust and particles and minimizes water absorption and retention. Alternatively, a Teflon filter is available for marine environments. The response time is slower when using the Teflon filter.
