Relative Humidity Sensor by Vernier

The Relative Humidity Sensor by Vernier is a low cost and reliable sensor that can be used to measure, record and monitor relative humidity while connected to a Maxwell hosted computer. The Relative Humidity Sensor includes the compatible Go!Link USB sensor interface to connect to your computers USB port.

The Relative Humidity Sensor and Go!Link combined are a perfect fit with Maxwell to record and monitor relative humidity in your environment that's between the range of 0 to 95% (± 5%). CHROMiX has tested and approved both Relative Humidity Sensor and Go!Link USB sensor interface for use only with Maxwell Client v5.x and newer.
