Overview
The HI98198 dissolved oxygen meter uses Optical inspection Fluorescence (OPDP) Measuring method to ensure the accuracy of dissolved oxygen measurement. With built-in standard methods and standards, it is easy to measure dissolved oxygen DO, biochemical oxygen consumption BOD, oxygen consumption rate OUR, specific oxygen consumption rate SOUR without complicated calculations. The HI764113 built-in temperature sensor Custom-made Optical inspection Fluorescence dissolved Oxygen electrode is suitable for the determination of dissolved oxygen in fresh and salt water (or seawater), with durability and Reliability.
Features
1. Data traceability: Query GLP data with a private key to ensure data security.
Data logging and management: Store up to 4000 measurement readings, support AutoEnd to automatically maintain stable readings.
3. Prompt function: Automatically detect and initialize the dissolved Oxygen electrode, and remind to replace the fluorescent dissolved Oxygen film.
4. Excellent features: host IP67, Electrode IP68 waterproof standard, large LCD display and backlight function, sturdy body suitable for on-site use.
5. Powerful data management function: USB-C interface to transfer data to computer, USB stick or Android device.
6. Special quick connection to dissolve Oxygen electrode: waterproof joint design, easy to disassemble and install.
Principle
The HI98198 uses Optical inspection Fluorescence (OPDP) Measuring method for dissolved oxygen measurement with built-in standard methods and standards. The HI764113 Optical inspection Fluorescence dissolved Oxygen electrode uses a dome hat design to repel bubbles, improving Sensitivity and Fast Response Time without minimum Flow velocity, polarization time or filler manipulation.
Applications
Determination of dissolved oxygen in fresh water, determination of dissolved oxygen in salt water (or seawater)
Standards
IP67 international waterproof standard, IP68 international waterproof standard
Steps
1. Install the dissolved Oxygen electrode using a dedicated quick connect waterproof connector.
2. Select single point or two point calibrated Automatic calibration, or user-defined single point calibrated.
3. Perform atmospheric pressure and temperature calibration (optional).
4. Start the measurement and use the AutoEnd key to automatically maintain a stable reading.
5. Transfer data to external devices through the USB-C interface.
Notice
• When the fluorescent dissolved oxygen film is damaged or lost, the instrument will remind to replace it, and it needs to be dealt with in time to avoid measurement problems.
• Ensure use under applicable environmental conditions (0 to 50 ° C, maximum relative humidity 100%).
• Use a dedicated HI920016 USB A-C data transmission cable for data management.
• Electrode maximum bearing depth is 20 meters/29 PSI, avoid using beyond the limit.
