Overview
The HANNA HI991404-02 water meter is a multi-functional measurement device that simultaneously monitors acidity pH (0.0 to 14.0 pH), conductivity EC (0 to 3999 μS/cm), total solid solubility TDS (0 to 2000 ppm) and sample temperature (0.0 to 60.0 ° C). The instrument features a waterproof design, large dual-line screen display and user-friendly Operating interface, supports 24-hour continuous monitoring, suitable for hydroponics, aquaculture, greenhouses and continuous water quality monitoring scenarios, and is compatible with laboratory suspension for space optimization and multi-batch sample rapid measurement.
Features
1. Waterproof design, adapt to a variety of environmental conditions
2. Appearance of the new model and large double-line screen display, easy to operate
3. With the screen calibrated operation steps prompt and stable indication
4. Two-button simple operation, user-friendly interface
5. Supports 24-hour continuous monitoring of pH, EC, TDS, and temperature
6.1-2 point acidity automatic identification calibrating, built-in standard calibrating point
7 conductivity and TDS single point automatic identification calibrated
8. Can be suspended, saving laboratory space and supporting multi-batch data retrieval
Principle
The meter is measured by standard HI1293 pH Electrode and HI7630 EC-TDS Electrode. The pH measurement uses automatic temperature compensation. The conductivity and TDS measurement have adjustable temperature compensation factor (β = 0.0 to 2.4%/℃) and adjustable conversion factor (0.45 to 1.00) for accurate data collection. The instrument has built-in automatic identification Adjustment, which is calibrated with preset standard points to ensure measurement Stability and accuracy.
Applications
Hydroponics, aquaculture, greenhouses, continuous water quality monitoring, laboratories
Steps
1. Connect Standard Electrode and Power Adapter
2. Turn on the instrument and calibrate according to the screen prompts
3. Measurement mode (pH, EC, TDS or temperature)
4. Immerse Electrode in Sample and Read Display Data
5. Operating interface for data retrieval or setup
Notice
• Ensure use in 0~ 50 ° C, maximum 95% relative humidity (non-condensing) environment
• Electrode check before calibrating to avoid contamination
• Use a 12VDC adapter for the power supply, do not operate under overvoltage
• Electrode wire length is 2 meters, avoid excessive bending when using
• Keep drying during storage to prevent Electrode damage
