Nephelometric turbidity meter AMI Turbiwell 7027

High precision, non-contact nephelometer based on ISO 7027 (EN 27027, DIN 38404) for the continuous measurement of turbidity in pure water, potable water, surface water treatment and effluent. Range: 0.000 to 200.0 FNU with a precision of ±(0.003 FNU + 1 % of reading). Turbidimeter with sample chamber and valve for chamber drain. Optional sample degasser for the prevention of interfering bubbles formation in the sample. High precision secondary standards for quality assurance Specifications Non-contact turbidity (Nephelometer according to ISO 7027) with control electronics, sample chamber, drain value for chamber purging (manual or automated) and sample degasser (optional) Complete system mounted on PVC panel (400 x 850mm), factory calibrated (formazine) and ready for operation Measuring and control transmitter on an aluminium case (IP 66). Two signal outputs freely scalable and with simulation mode. Potential-free alarm contact as summary alarm indication for programmable alarm values and for instrument faults. Monitoring of maintenance requirements. Measuring Range: 0 - 200.0 FNU/NTU Precision: ± (0.003 FNU + 1% of reading) Accuracy (based on formazine primary standard): Range 0 - 40 FNU ± (0.01 FNU + 2% of reading) Range > 40 FNU: ± 5% of reading Sample Conditions: Flow rate: Approx. 20 - 60 l/h Temperature: up to 45°C Power Supply: 100 - 240 VAC (±10%) 10 - 36 VDC
