Air Flow Measurement

Anyone can use this meter with its plain language screen prompts, soft keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese No need to worry about DO probe compatibility – the meter accepts and automatically recognizes Orion polarographic and RDO optical/ luminescence-based probes Accurate results are easy with automatic temperature, manual salinity and automatic/ manual barometric pressure compensation Dont miss a reading – AUTO-READ* locks in the stable reading on your screen and ready indicator alerts when readings are stable Calibrate using water-saturated air, air-saturated water, a Winkler titration or zero point calibration Non-volatile memory holds up to 1000 data points with time and date stamp Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software Four AA batteries (included) provide over 800 hours of operation or purchase the universal power adapter (sold separately) to use AC power Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing Three year meter replacement warranty Certifications: CE, TUV, FCC Class A limits Range -5° to 105°C (23° to 221°F) Resolution 0.1 (0.1) Relative Accuracy ±0.1 Concentration Range Polarographic: 0 to 90mg/L, RDO optical: 0 to 50mg/L Concentration Resolution 0.01, 0.1 Relative Accuracy Polarographic: ±0.2mg/L, ±2%, RDO optical: ±0.1mg/L up to 8mg/L, ±0.2mg/L up to 20mg/L, 10% of reading beyond, ±2% % Saturation Range Polarographic: 0 to 600, RDO optical: 0 to 500 % Saturation Resolution 0.1, 1 Salinity Factor 0 to 45 ppt, manual Calibration Water-saturated air, air-saturated water, manual (Winkler) and zero point Inputs 8-pin mini-DIN Sensor Types Polarographic or RDO (optical/luminesce-based) DO Data Management 1000 points with date/time stamp Output RS-232, USB Display Graphic LCD, simultaneous display of measurement, temperature, date/time, and more Power Supply Four AA batteries or optional universal AC line voltage Relative Humidity 5 to 85% noncondensing Warranty 3-year meter replacement
