Yosemitech Y600-A handheld instrument is independently developed by Yosemitech. It provides keyboard and backlight with comprehensive functions, simple operation and brief interface. The instrument is a portable device that can automatically recognize Yosemite'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.
The dissolved oxygen sensor 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 Yosemitech optical dissolved oxygen probe is as low as 30 seconds, making the measurement of dissolved oxygen more accurate, more stable, faster and more convenient.

- Powered by a long-life rechargeable lithium battery for both the handheld main unit and sensors.
- Equipped with a built-in air pressure sensor for automatic dissolved oxygen level compensation.
- Features an intuitive interface requiring no complex instructions for easy operation.
- Automatically identifies digital sensors, stores data, and enables immediate measurement upon startup.
- Each sensor is field-replaceable, calibratable, and maintainable, offering users flexibility and convenience.
