The Triton TR8 Clear Water Sensor is ideal for all phases of drinking water processing including filter backwash. The sensor operates over a wide measurement range with output available in multiple units of 0.000 to 9,999 FNU, 0.00 to 3,000 ppm, 0.0 to 3.0 g/L, or 0 to 20%. It features an error rate of less than 5% of reading with repeatability greater than 1% of reading. Its assembly relies on a long life near an infrared LED light source (880 nm) and the 90-degree scattered light method in accordance with ISO 7027/EN 27027. Triton's sensor was developed for rugged water treatment environments and designed to operate at ambient temperatures from -5°C to +50°C (20°F to 120°F).
