Yosemitech Y600-A Handheld Instrument provides keyboard and backlight with comprehensive functions, simple operation and brief interface. The instrument is a portable device that can automatically recognize Yosemitech's digital sensors including optical dissolved oxygen, 4-electronic conductivity, turbidity, chlorophyll, BGA, OIW and TSS ,and can measure, display, log. The microprocessor based meter can transmit USB signals and perform sensor calibration easily on a single platform.
Y507-A Dissolved Oxygen Probe adopts the internationally leading fluorescence lifetime technology, which is based on the quenching principle of specific substances to active fluorescence in physics. The remarkable advantage of this fluorescence method in measuring dissolved oxygen is that it does not consume oxygen in the measurement process, so there is no flow rate limit, no need to preheat electrolyte, no need for maintenance and frequent calibration. The response time of optical dissolved oxygen probe is as low as 20 seconds, making the measurement of dissolved oxygen more accurate, more stable, faster and more convenient.
Y600-A&Y507-A Portable Dissolved Oxygen Meter, with automatic temperature and pressure compensation, salinity manual input compensation function; It supports automatic locking of dissolved oxygen detection value and setting of filtering mode. This Optical Do Meter has high accuracy and stability, and widely used in Wastewater treatment facilities, Aeration tanks, Aquaculture systems, Environmental monitoring stations, Research laboratories, Industrial process control.
