Vernier Turbidity Sensor TRB-BTA Information The Vernier Turbidity Sensor TRB-BTA is a portable and easy-to-use sensor that measures the turbidity of water samples. Turbidity is a measure of the cloudiness of water, and it is an important indicator of water quality. High turbidity can indicate the presence of suspended particles in the water, which can make it difficult for aquatic life to survive. The Vernier Turbidity Sensor TRB-BTA has a range of 0 to 200 NTU (nephelometric turbidity units), and it is accurate to ±2 NTU for readings under 25 NTU and ±5% of readings above 25 NTU. The sensor comes with a 100 NTU standard for quick calibration, and it can be used with a variety of Vernier data collection interfaces, including the LabQuest 2, LabQuest Mini, and LabPro. Image:
