Benchtop Turbidimeter

Description :

The ST 300 is a benchtop turbidity, chlorine and color meter with wide range and high accuracy. The ST 300 meets ISO 7027 standards for turbidity, follows standard methods 4500-CI-G for chlorine and Standard Methods 2120-C for color. The ST 300 meter meets EPA 180.1 for turbidity and EPA 330.5 for chlorine and follows standard methods 2120-C for color. The turbidity range is 0 to 4000 NTU with a MDL of 0.05 NTU. The free and total chlorine range is 0 to 10 ppm with a MDL of 0.03 ppm. The meter can store 500 data points which can be downloaded to a computer. Features 7 different languages, and runs on rechargeable batteries or a USB computer/wall adaptor.
