Frequent Ask Question - H2 BLE-9002 Bluetooth Hydrogen Meter

1: What is the measuring range and accuracy of the H2 BLE-9002 hydrogen meter?

The H2 BLE-9002 measures dissolved hydrogen (H₂) in the range of 0 to 2990 ppb (equivalent to 0.00 to 2.90 ppm) with an impressive accuracy of ±1 ppb (±0.01 ppm). It also measures water temperature from 0.0°C to 60.0°C (32.1°F to 140.0°F) with ±0.5°C accuracy, making it suitable for both casual home use and professional laboratory applications.

2: How does the Bluetooth connectivity work on the BLE-9002 hydrogen tester?

The BLE-9002 features built-in Bluetooth that pairs with a dedicated smartphone app (available for iOS and Android). Once connected, the app allows you to sync real-time readings, save historical data to the cloud, generate trend charts, and share results. The device also functions fully as a standalone meter without the app — the Bluetooth feature enhances data management but is not required for basic testing.

3: Is the H2 BLE-9002 waterproof, and what is the IP rating?

Yes, the H2 BLE-9002 has an IP67 waterproof rating, which means it is protected against dust ingress and can withstand immersion in water up to 1 meter deep for 30 minutes. This makes it safe for use in wet environments such as aquariums, hydroponic systems, and spa settings. However, we recommend avoiding prolonged submersion and always drying the device after use.

4: What type of battery does the H2 BLE-9002 use, and how long does it last?

The BLE-9002 hydrogen meter is powered by a standard LR44 button cell battery. Battery life depends on usage frequency, but under normal conditions, a single LR44 battery provides approximately 200–300 hours of continuous operation. The HD LCD display includes a low-battery indicator to alert you when replacement is needed. LR44 batteries are widely available and inexpensive to replace.

5: Can I replace the electrode on the BLE-9002, and how often should I do it?

Yes, the H2 BLE-9002 features a replaceable high-sensitivity electrode, which is a major advantage over disposable testers. Electrode lifespan typically ranges from 6 to 12 months depending on usage frequency and water conditions. Signs that replacement is needed include slower response times, inconsistent readings, or failure to calibrate properly. Replacement electrodes are available separately from Uniglobal Business.

6: What applications is the H2 BLE-9002 hydrogen meter best suited for?

The BLE-9002 is versatile and ideal for multiple applications:

Drinking Water Testing: Verify hydrogen levels in hydrogen-rich water bottles and pitchers.
Aquariums: Monitor dissolved hydrogen for healthy fish and aquatic plants.
Hydroponics: Optimize nutrient water quality and growing conditions.
Water Filters & RO Systems: Check the efficiency of hydrogen-generating purifiers.
Spa & Wellness Centers: Validate hydrogen water machine output.
Laboratories: Conduct research and quality control with 1 ppb precision.
