Portable Water Turbidity Test Analyzer EZL-PTA11 is built specifically for water quality tests, offering consistent and precise readings, particularly in the low turbidity range, with a low detection limit of 0.10NTU. The measuring range is 0 to 1000 NTU, with automated changeover between ranges. The instrument is equipped with two 90° and 180° detectors, with the 90° detector receiving scattered light and the 180° detector receiving transmitted light.
