SALscan20 is a pocket multi-parameter salinity tester that used to measures the salinity and conductivity of high concentration liquids, e.g., salt water, sea water, etc.   Features: Standard platinum sensor provides fast and reliable measurements. Up to 3 points calibration allows user to uses customized calibration     solutions. Manual temperature calibration provides accurate measured value. Automatic Temperature Compensation ensures highly accurate     measurements over the entire range. Hold function freezes the current displayed value for easy viewing     and recording. Setup menu lets user customize calibration points, temperature unit,     automatic or manual hold function to meet personal preferences. Reset feature allows user to resume all of the default settings. Auto-power off feature helps you effectively conserve battery life. Replaceable electrode reduces maintenance and replacement cost. Waterproof feature to ensures complete protection in harsh     environments.  

Bante980 is professional dissolved oxygen meter designed for laboratory applications. The meter is equipped with a polarographic sensor for measurement of dissolved oxygen concentration or percent saturation in water. Features: 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 either temperature units between degrees Celsius (°C)     and degrees Fahrenheit (°F). Automatic Temperature Compensation (ATC) ensures high accuracy     of measurements. Manual temperature calibration provides accurate temperature value. Calibration due reminder prompts you to calibrate the meter regularly. Automatic endpoint function freezes the stable measured values for     easy reading and recording data. Help message as a operational guide to helps you understand how     to use meter.
