Overview
The HC2S3, manufactured by Rotronic, 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.
Note: For customers with an HC2S3, the HC2A-S3 replacement sensor is available.
Key Advantages
Superior performance and reliability
Technical Description
The HC2S3 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.
