Benchtop pH/DO Meter, w Electrodes, 9V

The labForce DO700 Benchtop pH/DO Meter features automatic calibration, automatic temperature compensation, data storage, timing measurement, clock display, RS-232 output, function setting and self-diagnose. It has three measuring modes for your specific measuring needs: stable measurement display mode, timing measuring mode, and continuous measuring mode. The DO electrode is capable of automatic temperature compensation and automatic salinity compensation as well as automatic air pressure compensation inside meter to make DO measuring mode has temperature, air pressure and salinity automatic compensation, easy to use, accurate to measure. The polarogram type DO electrode has a special electrode calibration cap. It only needs 3 to 5 minutes for electrode polarization. The electrode uses combination diaphragm cap which very convenient to use, and each DO electrode is equiped with three spare diaphragms caps. Choose from 13 kinds of pH buffer solution for automatic buffer recognition. It has a reliable structure with a large LCD with blue backlit, and all connectors are protected by silicon caps, making it IP54 waterproof and dustproof. Accuracy: ±0.01 pH, Range: -2.00-19.99 pH, ATC, Auto Calibration with automatic buffer recognition. Uses advanced digital filtering technology for improved response time and accuracy. GLP standard data management, 900 data sets of storage, manual/ auto timing storage, RS232 data output. 3 measurement modes: stable measurement display mode, timing measuring mode, and continuous measuring mode. High purified water and ammonia added purified water pH measuring modes available. Includes a EH redox potential measuring mode. DO electrode uses automatic temperature compensation and automatic salinity compensation as well as automatic air pressure compensation. The polarogram type DO electrode uses a special electrode calibration cap for faster electrode polarization (3 to 5 minutes). The electrode uses a combination diaphragm cap. Each DO electrode comes with three spare diaphragms caps. 2-Year Warranty
