EziLab offers the Portable Water Turbidity Test Analyzer EZL-PTA10, a handheld NTU tester that shines light through a water sample and reads the scatter with two detectors set at 180° and 90° to cancel color effects. The dual-path optics measure 0–20 NTU down to a 0.10 NTU detection limit, hold ±0.1 NTU or 5% tolerance, and repeat within ±0.05 NTU below 5 NTU. Calibration takes up to four standards, zero drift stays within ±0.3% of full scale over 30 minutes, and a suspended solids mode reports mg/L. The 290 g IP65 body carries 5,000 records in memory, charges and transfers data over one USB port, and draws little power. Municipal water authorities, drinking water plants, environmental monitoring agencies, industrial wastewater operators, bottling companies and aquaculture farms use this portable turbidity meter for quick on-site clarity checks. Field tasks include reservoir and intake checks, filter breakthrough monitoring, distribution network spot tests, effluent discharge compliance, membrane integrity checks and pond clarity surveys. Choose it over benchtop turbidimeters when readings are needed at the source within minutes of sampling. Air bubbles and a fingerprint on the sample vial both inflate an NTU reading; let a sample stand a moment, wipe the glass, and invert gently before measuring. Field instruments are filed from Lab Equipment through Water Quality Analyzer.
