Overview
HI98130 high-range pH-EC-TDS- ℃ water quality analysis and measurement instrument adopts the new Appearance design, dual-line screen display, with the screen to calibrate the operation steps prompts, user-friendly Operating interface, stable indication mark, two-button simple operation, convenient operation. Can display pH (EC/TDS) and ℃ measurement at the same time, pH, EC, TDS quick switching, automatic identification calibrate, automatic temperature compensation, to ensure the accuracy and Stability of measurement in different environments. Battery replacement is simple and fast, with BEPS low-power error-proof system to avoid erroneous measurement, suitable for on-site environment and can also provide laboratory-grade measurement results.
Features
1. An instrument with three sensors integrated.
2. Waterproof design, if you want to transfer it into the sample, it can float on the surface.
3. With automatic temperature compensation function.
4. Provides a stable reading function that locks the reading on the display for recording Measured values.
5. With low battery reminder function, if there is not enough battery, the instrument will automatically shut down.
6. With automatic shutdown function, it automatically shuts down after 8 minutes of not using it to extend Battery life.
Principle
The instrument performs measurement by in-line pH Electrode, uses automatic identification and calibrating mode for pH calibration, and has automatic temperature compensation function. For conductivity (EC) and total dissolved solids (TDS) measurement, single point calibrating mode is used, and temperature compensation can be performed by adjustable compensation coefficient to ensure the accuracy of measurement results.
Applications
Water quality analysis, on-site environment monitoring
Steps
Step 1 Power on.
2. Calibrate according to the screen prompts (pH is 1-2 points to automatically identify calibrate, EC and TDS are single point calibrate).
3. Insert Electrode into the sample to be tested.
4. Wait for the reading to stabilize, and then lock the reading for recording.
5. Fast switching between pH, EC, TDS Measurement modes.
6. After use, the instrument will automatically shut down after 8 minutes of inoperation.
Notice
• Please ensure that the instrument is used in an environment of 0 ° C to 50 ° C (32 ° F to 122 ° F) with a maximum of 100% RH.
• Please use 4 1.5V button batteries when replacing the battery.
• The instrument has a low battery reminder function, which will automatically turn off when the battery is insufficient. Please replace the battery in time.
• The instrument has an automatic shutdown function to save power. Please keep it safe when not in use for a long time.
• When calibrating, use the standard calibrating point built into the instrument (pH4.01, 7.01, 10.01 or pH4.01, 6.86, 9.18) and the specified EC (1413 μS/cm) and TDS (1382 ppm) calibrating points.
• For EC/TDS measurement, the temperature compensation factor β (0.0 to 2.4%/℃) and TDS factor (0.45 to 1.00) can be adjusted as needed.
