DO-66笔试溶解氧测试仪

Product Description: Overview: The DO-66 portable dissolved oxygen analyzer (hereinafter referred to as the instrument) is designed for convenient on-site operation. The instrument consists of two parts: a sensor and an electronic unit. The sensor employs a membrane-type dissolved oxygen electrode, while the electronic unit integrates an operational amplifier and a microcomputer chip, featuring automatic temperature compensation. >Portable ·Compact and lightweight design. ·Includes a carrying case made of durable PP engineering plastic for easy transport and storage. >Long Battery Life ·Powered by two AAA batteries, providing up to approximately 600 hours of continuous use. ·Features a low-voltage warning for user convenience. A prompt will appear on the screen when the battery is nearly depleted, reminding users to replace the batteries promptly. >Waterproof ·Fully waterproof (except for the battery compartment) to protect internal circuitry. >Automatic Calibration ·Equipped with 0% and 100% automatic calibration buttons for easy operation. >Temperature Compensation ·Automatically detects and converts values based on the difference between actual solution temperature and standard temperature, ensuring more accurate measurements.
