Overview
HI9146-04 Microcomputer Dissolved Oxygen Meter is a dissolved oxygen meter of HANNA brand, suitable for the determination of dissolved oxygen in different water quality and wastewater in various industries. The instrument is equipped with high-performance Polarographic Sensor Dissolved Oxygen Electrode, which generates current through a specific dissolved oxygen film to ensure stable and accurate measurement. Users can choose mg/L (ppm) or% Saturation dissolved oxygen% mode for measurement.
Features
1. Large screen background light LCD, operation guide display
2. The battery display icon reminds to replace the battery in time, and the measurement is accurate and reliable
3. Automatic compensation of height, salinity and temperature, Automatic calibration function in air
4. Polarography dissolved Oxygen electrode for field measurement
5. Measurement results are expressed in ppm (mg/L) or%
Principle
The dissolved oxygen meter uses a high-performance Polarographic Sensor Electrode, which generates a current through a specific dissolved oxygen film to ensure stable and accurate measurement. The instrument can choose 1 point or 2 point calibrating, and it is recommended to use HI7040 zero oxygen standard solution for zero point calibrating or automatic 100% calibrating in air.
Applications
Water quality and wastewater in various industries
Steps
1. Select calibrate mode: single point or double point calibrate
2. Perform calibrating: use HI7040 zero oxygen standard solution for zero point calibrating or automatically perform 100% calibrating in air
3. Set compensation: choose height compensation and salinity compensation
4. Start measurement: Use the HOLD key to lock the measurement reading
5. Record data: It is convenient for users to accurately record data
Notice
• Operating ambient temperature range of 0 to 50 ° C (32 to 122 ° F) with a maximum relative humidity of 95%
• Pay attention to the battery display icon in time to ensure that the battery is sufficient
• It is recommended to use HI7040 zero oxygen standard solution for zero point calibrating
• Height compensation and salinity compensation can be selected as needed during measurement
• Use the HOLD key to lock measurement readings to ensure accurate data recording
