Portable Turbidity meter 25-PTM105 Catalog

Portable Turbidity meter 25-PTM105

Overview :

Portable Turbidity meter 25-PTM105 measures water clarity using 90° scattered light principle with infrared-emitting diode at 850 nm. It features silicon photodiode detector, dual measuring ranges of 0–100 NTU and 100–1000 NTU, minimum readout of 0.01 NTU, and ±6% error value (±2% F.S). Powered by AC 220V/50Hz or five AA alkaline batteries, it weighs 1.5 kg with dimensions of 370 × 260 × 15 mm. Includes USB communication interface, memory for up to 20 data sets, calibration at seven points, zero drift of ±0.5% F.S., and operates within 5–4°C temperature range. Suitable for quality control in drinking water treatment, environmental monitoring, food & beverage production, pharmaceutical processes and industrial wastewater analysis requiring precise turbidity assessment in field or laboratory settings.
