Overview
The HANNA HI981420-02 Water Quality Analyzer is a versatile device that continuously monitors pH, conductivity (EC), total solids solubility (TDS) and sample temperature. Measurement ranges are pH 0.00 to 14.00, temperature 0.0 to 60.0 ° C, EC 0.00 to 10.00 mS/cm, TDS 0 to 5000 ppm or 0 to 7000 ppm. Simple and easy to use design, equipped with a large LCD screen and green background light, supports fast one-click calibrating and 24-hour continuous monitoring. It is suitable for hydroponics, aquaculture, greenhouses and water quality monitoring. It is also suitable for laboratory suspension use to optimize space utilization and data management.

5. User friendly: large screen LCD green background light, environment ray of light Sensor automatically adjust luminance.
6. Data management: Automatically record the last 30 days of data, USB-C interface transmission.
7. Alarm function: High and low alarm LED indicator, can be set to turn on or off.
8. Wide range of applications: suitable for hydroponics, breeding, greenhouses and laboratories and other environments.
Principle
The water quality meter is measured by the built-in HI1285-8 Electrode integrated pH, EC, TDS and temperature sensor. pH measurement is based on potentiometry, EC and TDS measurement is based on the principle of conductivity, and temperature measurement is realized by the built-in Sensor. The device automatically performs temperature compensation (pH temperature compensation automatic, EC-TDS compensation β = 1.9%/℃) and uses a dedicated Quick Cal standard solution for rapid calibration to ensure measurement accuracy. Data is automatically recorded and stored, and the GLP function is supported to track calibrate history.
Applications
Hydroponics, aquaculture, greenhouses, continuous water quality monitoring, laboratory suspension
Standards
Good Laboratory Practice (GLP)
Steps
1. Connect the Power Adapter and turn on the device.
2. Use pH and EC-specific Quick Cal standard solution for one-button rapid calibrating.
3. Electrode is immersed in the sample and the device automatically starts the measurement.
4. Read pH, EC, TDS and temperature data through a large-screen LCD.
5. Set the alarm high and low values, and you can choose to turn on or off the alarm function.
6. Data is automatically stored, and historical data can be retrieved through the USB-C interface.
7. Clean Electrode and turn off equipment after use.
Notice
• Make sure the Electrode is properly connected and immersed in the sample.
• Check the valid period of the standard solution before calibrating.
• Avoid use in a condensing environment, the applicable environment is -5~ 50 ° C and the maximum 95% RH is non-condensing.
• Regularly clean the Electrode to maintain Measurement accuracy.
• Data storage interval is 15 minutes, timely backup of important data.
Alarm settings can be adjusted as needed to ensure safety.
• Use original accessories to avoid incompatible power supplies.
