In October/November of 2018 we shipped some UVB Sensor (UVB-BTA) that were assembled with the label on the tube that says Relative Humidity Sensor (RH-BTA). They were sold as UVB sensors and came in bags labeling them as UVB sensors and they do work correctly as UVB sensor. However, the only label on the device is for a Relative Humidity sensor.

To identify these sensors, (besides the fact that when you plug them into an interface they will autoID differently than the label on the sensor,) you can look at the end of the tube. The UVB sensor has a solid translucent piece of plastic at the end, while the real Relative Humidity sensor has a cage type end that lets in air.

If you have any of the UVB sensors that are labeled as Relative Humidity, please contact Vernier Technical Support to discuss. We can provide you with the correct label to prevent confusion. To reach us by phone, call 1.888.837.6437 or email support@vernier.com.
