Precision Dissolved Oxygen Meter Precision Dissolved Oxygen Meter 1 or 2 points auto-calibration (100% in saturated air or air-saturated water,0% in zero oxygen solution). Automatically compensates salinity and barometric pressure after manual input. Selectable readout in ppm, mg/L or % saturation. Selectable temperature units between degrees Celsius (°C) and degrees Fahrenheit (°F). Automatic Temperature Compensation ensures high accuracy of measurements. Automatic endpoint function freezes the stable measured values for easy reading and recording data. Calibration due reminder prompts you to calibrate the meter regularly. Help message as an operational guide to helps you understand how to use meter. Setup menu lets user customize calibration points, resolution, stability condition of measurements, temperature units, date/time to meet personal preferences. Reset function allows user to returns all settings to the factory default values. Expand memory stores and recalls up to 500 readings. Built-in real-time clock stamps stored data to meets GLP standards. Stored data can be transferred into personal computer via USB communication interface MODEL LMODO-50 SPECIFICATION Make LAB Dissolved Oxygen Range 0.00-20.00mg/L or ppm Resolution 0.1, 0.01 ppm, (Selectable) Dissolved Oxygen Accuracy +0.2mg/L or ppm Saturation of Oxygen 0.0-200.0% Accuracy ± 2.0% Temperature Range 0.0-50.0°C Temperature Accuracy ± 0.5°C Temperature Compensation 0-50°C, Automatic Salinity Correction 0-50g/L Barometric Pressure Correction 60.0-112.5kPa, 450-850mmHg Calibration Points 1 0r 2 points (100% in air or 0% in zero oxygen solution) Memory & Output 500 data sets with Date/Time stamping & USB Interface Power Supply DC 5V adapters, using AC 220V/50Hz Dimensions LxWxH (mm) & Weight 210 x 188 x 60 & 1.2 kg
