Overview
The HANNA HI991405-02 water meter is a multifunctional measurement device that simultaneously monitors acidity pH (0.0 to 14.0 pH), conductivity EC (0.00 to 20.00 mS/cm), total solid solubility TDS (0.00 to 10.00 g/L) and sample temperature (0.0 to 60.0 ° C). It features water resistance, a new Appearance design, an oversized dual-line screen display and a user-friendly Operating interface. It supports 24-hour continuous monitoring. It is suitable for hydroponics, aquaculture, greenhouses and water quality continuous monitoring. It is also suitable for laboratory hanging use, efficient use of space and supports rapid measurement of multiple batches of samples.
Features
1. Waterproof function design, adapt to a variety of environments;
2. Appearance and large double screen display, easy to operate;
3. With the screen to calibrate the operation steps prompts and stable indication signs;
4. Two-button simple operation, user-friendly interface;
5. Support 24 hours continuous monitoring of pH, conductivity, TDS and temperature;
6. Automatic identification calibrating: pH supports 1-2 points, EC and TDS support single point;
7. Suitable for suspended use in laboratories, saving space.
8. Adjustable temperature compensation and conversion factor to improve measurement flexibility.
Principle
The water quality meter is measured by built-in Electrode (HI1293 pH Electrode and HI7630 EC-TDS Electrode), pH measurement uses automatic temperature compensation, conductivity and TDS measurement support adjustable temperature compensation factor (0.0 to 2.4%/℃) and adjustable conversion factor (0.45 to 1.00). The instrument automatically recognizes the calibrating point and has built-in standard calibrating points (pH: 4.01, 7.01, 10.01; EC: 12.88 mS/cm; TDS: 6.44 g/L) for fast and accurate continuous monitoring.
Applications
Hydroponics, aquaculture, greenhouses, continuous monitoring of water quality, suspended use in laboratories
Steps
1. Connect standard Electrode (HI1293 pH Electrode and HI7630 EC-TDS Electrode);
2. Turn on the power supply and use the 12VDC Power Adapter for power supply;
3. Calibrate according to the screen prompts: pH can choose 1-2 point automatic identification calibrate, EC and TDS for single point automatic identification calibrate;
4. Immerse Electrode into the sample and the instrument automatically displays pH, EC, TDS, and temperature readings.
5. In the continuous monitoring mode, it can be suspended and used to retrieve measurement data.
Notice
• Make sure the power supply is a 12VDC adapter to avoid voltage mismatch;
• Operating Environment Temperature between 0~ 50 ° C, relative humidity not exceeding 95% and no condensation;
• Before calibrating, confirm that the built-in standard points are accurate to avoid measurement errors;
• Electrode wire length is 2 meters, use to avoid excessive pulling;
• Regularly check Electrode status to ensure Measurement accuracy;
• Instrument weight 190g, avoid heavy pressure when storing.
