Description Overview GAOTek dissolved oxygen analyser is one of the intelligent online chemical analysis instruments. It is widely used in continuous monitoring of dissolved oxygen, saturation, oxygen partial pressure and temperature. The continuous monitoring data is realized by remote transmission monitoring and recording through the transmission output connection recorder. Features Using photoelectric technology, low maintenance rate and high stability No oxygen consumption, no flow rate requirements, can be measured by purified water Good compatibility, the sensor provides standard 4 mA to 20 mA signal, which can be interchanged with E H sensor Strong anti-interference ability, full digital processing technology and full stainless steel shell shielding Automatic temperature compensation Technical Specifications Measuring principle Fluorescence method Meter size 3.8 in x 3.8 in x 5.1 in (96 mm x 96 mm x 130 mm) Measuring range Oxygen content 0 mg/ L to 20mg/L; Saturation 0% to 200% Accuracy ±1% FS Resolution Oxygen content 0.01 mg/L; Saturation 0.1% Repeatability ±0.5% FS Temperature range 14 °F to 140 °F (-10 °C to 60 ℃) Resolution(temperature) 32.2 °F (0.1 ℃) IP grade IP 68 Correction accuracy (temperature) 32.9 °F (±0.5 ℃) Temperature measurement type Manual/Auto (NTC 10 K / PT 1000) Power supply AC 220 V 10%, 50Hz to 60Hz Relay alarm 250 VAC/ 3 A Communication RS 485(compatible with MODBUS RTU) Transmitting function Isolated transmission 4 mA to 20 mA output, maximum loop 750 Ω, 0.1% FS
