DO-66 Dissolved Oxygen Analyzer Pen Type Intelligent Dissolved Oxygen Tester LCD Display for Aquarium Fish Tank Aquaculture

DO-66 pen-type intelligent dissolved oxygen analyzer (hereinafter referred to as the instrument) is designed to facilitate the user's on-site operation. The instrument can be divided into two parts: sensor and electronic unit. The sensor uses a thin film dissolved oxygen electrode. The electronic unit is an integrated operational amplifier + a microcomputer chip with automatic temperature compensation. It has an LCD display for easy reading in dark environments, and is the best assistant for intelligent dissolved oxygen analysis in aquarium fish tanks.

Specification: Product name:dissolved oxygen meter Material:plastic+metal Display:LCD display Power supply: 2 *AAA batteries (not included) Residual current: No more than 0.15mg/L Response time: No more than 15 seconds Measuring range: Oxygen concentration:0.0~16.5mg/L Dissolved oxygen saturation:0.0~199.9% CF:0.0~50°C/32.0~122°F

Calibration: Rinse the electrode well with DI water or rinse solution. press ON/OFF to turn on the machine. Dip the electrode into the zero oxygen solution for at least 3 minutes, and keep shaking gently until the display value stabilizes. Press and hold the ON/OFF key until the second line of display shows "CAL" character, continue to shake the electrode gently, when the display value is stable, press [% / L/mg] key, it shows DO value 0%, complete the zero calibration. Clean the electrode, dip the electrode into the saturated dissolved oxygen solution and keep shaking the electrode gently until the displayed value is stable. Shake gently and press ON/OFF key until the second line of the display shows "CAL" character, then press ℃/°F key, the DO value of 100.0% is shown at this time, the slope correction is finished. Note: If you accidentally enter the calibration state (the second line displays CAL characters) due to an operation error, press the [ON/OFF] key briefly to exit. Note:Dont include any calibration, electrolytes and liquids
