3. Calibration

For accurate measurements, regular calibration is essential. The tester comes with calibration solutions for pH and ORP. Refer to the specific instructions in the included manual for detailed calibration steps for each parameter.

Figure 6: Calibration solutions included.

• pH Calibration: Typically requires pH 4.00 and pH 7.00 buffer solutions.
• ORP Calibration: Uses a 222mV ORP calibration solution.
• Other Parameters: TDS, EC, and Salt measurements may require specific calibration solutions or can be calibrated relative to known standards.

Operating Instructions

1. Basic Operation

1. Turn On: Press the "ON/OFF" button to power on the device.
2. Select Mode: Press the "MODE/CAL" button to cycle through the different measurement parameters (pH, H2, TDS, ORP, EC, Salt, Temp).
3. Immerse Electrode: Gently immerse the electrode into the sample liquid, ensuring the probe is fully submerged.
4. Stabilize and Read: Wait for the reading to stabilize on the screen (usually a few seconds), then record the value.
5. Hold Reading: Press the "HOLD/TEMP" button to freeze the current reading on the display. Press again to release.
6. Temperature Unit: While in temperature display, press and hold "HOLD/TEMP" to switch between °C and °F.
7. Rinse and Store: After each use, rinse the electrode with distilled or purified water and replace the protective cover.
8. Turn Off: Press the "ON/OFF" button to power off the device.

2. Understanding Measurements

• pH: Measures the acidity or alkalinity of water.

  Figure 9: pH scale and common examples.

• EC (Electrical Conductivity): Indicates the concentration of dissolved ions in water. Higher EC generally means more dissolved solids.

  Figure 10: EC measurement and water quality.
• ORP (Oxidation-Reduction Potential): Reflects the water's ability to oxidize contaminants. Higher ORP values indicate greater oxidizing power.

  Figure 11: ORP levels and applications.

• TDS (Total Dissolved Solids): Represents the total concentration of dissolved substances in water. Lower TDS generally indicates purer water.

  Figure 12: TDS values and water quality types.

• H2 (Hydrogen): Measures the concentration of dissolved hydrogen gas. Hydrogen-enriched water is believed to have antioxidant properties.

  Figure 13: H2 measurement and benefits.
• Salt (Salinity): Measures the salt content in water, crucial for aquaculture and marine environments.

• Temperature: Measures the water temperature, which also affects other readings. The device features automatic temperature compensation.

Maintenance

1. Electrode Care

• Always keep the electrode clean.
• After each use, wash the electrode with distilled water or purified water.
• Avoid colliding or rubbing the electrodes during use to prevent damage.
• Ensure the electrode protection cover is replaced when not in use to keep the probe moist and protected.

2. Battery Replacement

When the low battery indicator appears on the display, replace all four LR44 1.5V button batteries simultaneously to ensure optimal performance.

3. Electrode Replacement

The electrode head is replaceable. If the electrode becomes damaged or its performance degrades significantly despite proper cleaning and calibration, it can be unscrewed and replaced with a new one. This allows for extended product lifespan.

Troubleshooting

User Tips

• Regular Calibration: Calibrate the tester regularly, especially if you notice inconsistent readings or after a period of heavy use, to maintain accuracy.
• Proper Storage: Always store the electrode with its protective cap on, ideally with a few drops of storage solution or distilled water to keep it moist.
• Avoid Cross-Contamination: Rinse the electrode thoroughly between different samples to prevent cross-contamination and ensure accurate results.
• Battery Life: Keep spare LR44 batteries on hand, as they are essential for the device's operation.
• Temperature Impact: While the device has ATC, extreme temperature differences between the sample and the device can still affect initial readings. Allow the device to acclimate if possible.
