High-performance portable conductivity/dissolved oxygen meter, including 5 measurement functions, the meter is suitable for outdoor measurement of sample conductivity, total dissolved solids (TDS), salinity, resistivity, dissolved oxygen concentration and saturation.
Conductivity/TDS/salinity/resistivity mode features:
• High-performance portable conductivity/dissolved oxygen meter with backlit LCD display.
• 1 to 5 point calibration, automatic identification of conductivity standards.
• Optional cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS conversion coefficient, linearity and pure water compensation, seawater and practical
salinity measurement modes.
Dissolved oxygen mode features:
• 1 or 2 point calibration, using air-saturated water or zero oxygen liquid.
• Salinity and atmospheric pressure compensation to eliminate measurement errors.
Common features:
• Automatic temperature compensation to ensure accurate measurement of the full range.
• Automatic end point lock, keep stable readings for easy browsing and recording.
• Calibration due reminder, reminding the user to calibrate the meter regularly.
• Automatic power off, effectively saving battery power consumption.
• The setting menu can customize the number of calibration points, display resolution, stability conditions, temperature units, date and time, etc.
• Reset function, automatically restore the meter to the factory default settings.
• Expand memory, store or recall up to 500 sets of data.
• USB communication interface, easy to transfer data to a personal computer.
• Multi-mode power supply scheme (battery, power adapter, computer USB port) to ensure the smooth application of the meter.
