Specifications

Setup

1. Battery Installation

The BLE-PH01 meter requires batteries for operation. Open the battery compartment (usually located at the top or back) and insert the batteries according to the polarity indicators. Close the compartment securely.

2. Mobile App Connection

The BLE-PH01 connects to your smartphone via Bluetooth for enhanced functionality. Download the "YINMIK Mobile App" from your device's app store (iOS/Android).

1. Ensure Bluetooth is enabled on your smartphone.
2. Turn on the BLE-PH01 meter by pressing the ON/OFF button.
3. Open the YINMIK Mobile App. The app will automatically search for and connect to the meter.
4. Once connected, the Bluetooth icon on the meter's LCD screen will illuminate, and you will see real-time data on your phone.

Operating Instructions

1. Basic Measurement

1. Turn on the meter by pressing the ON/OFF button.
2. Immerse the probe into the solution to be tested. Ensure the probe is fully submerged.
3. Wait for the reading to stabilize on the LCD screen.
4. Press the HOLD/TEMP button to hold the current reading on the display. Press again to release.
5. To switch between Celsius and Fahrenheit for temperature, use the corresponding setting in the mobile app or press the HOLD/TEMP button (if applicable, refer to app for full control).

2. pH Calibration

The BLE-PH01 supports automatic 5-point pH calibration. Regular calibration ensures accuracy.

1. Prepare the calibration buffer solutions (e.g., pH 4.00, 6.86, 9.18 for Asia standard; pH 4.00, 7.00, 10.01 for EU standard).
2. Clean the probe with distilled water and dry it gently.
3. Press the CAL button on the meter or initiate calibration through the mobile app.
4. Immerse the probe into the first buffer solution (e.g., pH 6.86 or 7.00). The meter will automatically recognize the buffer.
5. Wait for the reading to stabilize and for the meter/app to indicate successful calibration for that point.
6. Rinse the probe with distilled water and repeat the process for the remaining buffer solutions in ascending or descending order.
7. The app will display a calibration record for reference.

3. Setting Measurement Limits

You can set maximum and minimum measurement limits for pH and humidity within the YINMIK Mobile App. If a test result exceeds these set ranges, the value will be displayed in red on the app, providing a visual alert.

Maintenance

1. Probe Cleaning

After each use, rinse the probe thoroughly with distilled or deionized water to remove any residue. Do not wipe the probe vigorously, as this can damage the sensitive glass bulb. Gently blot dry with a lint-free tissue.

2. Storage

Always store the pH probe with its protective cap filled with a storage solution (or pH 4.00 buffer solution if storage solution is unavailable). Never store the probe dry or in distilled water, as this can shorten its lifespan.

3. Battery Replacement

When the battery indicator on the LCD screen shows low power, replace the batteries promptly to ensure accurate readings. Refer to the battery compartment for the correct battery type and orientation.
