Main features
1.I01-BP has a database of over 160 refrigerants that can recommend refrigerant filling pressure values.
Global environmental awareness is growing, and more environmentally friendly refrigerants will continue to be released in the future. Traditional refrigerant gauges cannot be updated in real time, so technicians have to keep buying new gauges to keep up with the environment, which is wasteful and inconvenient. Smart refrigerant gauges support OTA updates and have data on over 160 refrigerants. Intelligent computing recommends refrigerant filling pressure values.

2. Remotely track data changes to ensure worker safety and efficiency.
Technicians used to have to be physically present at the air conditioner to monitor the refrigerant gauge data. However, this could be dangerous, as air conditioners are often installed in high places or other dangerous locations.
Smart refrigerant gauges can be monitored remotely via its dedicated Bluetooth on the mobile app, with a range of up to 400 meters (in open areas). This allows technicians to monitor multiple gauges at once, which can greatly improve work efficiency.

3. Properly installing the refrigeration equipment can prevent excessive refrigerant replenishment and machine damage.
Technicians used to have to rely on their experience to determine how long each step of an air conditioner installation would take. However, human errors in the readings of traditional refrigerant gauges could often lead to damage to the air conditioner, refrigerant leaks, or the need to rework or repair the air conditioner. With vacuum leak alarms and pressure records, technicians can now more accurately determine the time required for each step, which can help to reduce machine wear and tear and the need to refill the refrigerant.

4. Replacing traditional monitoring methods with smart refrigerant gauges
I01-BP overcomes the limitations of traditional analog with interactive operation, durability, and accurate readings. It utilizes backlit LEDs for visibility and offers readings through a user-friendly app.
5. Wide-ranging pressure measurement range
Wide-ranging pressure measurement from -14.7PSI to 800PSI (resolution 0.1) with interactive features for easy operation.

6. Built-in absolute atmospheric pressure, no need for calibration
The gauge has a zeroing and cancellation function that can be used without interrupting the installation process of HVAC.

7. Multiple users can monitor one gauge, and one user can access multiple gauges simultaneously
The app allows multiple users to connect to the gauge simultaneously, so that multiple people can monitor one gauge or one person can monitor multiple gauges. This can improve overall work efficiency.

8. Robust and weatherproof
Sensors are designed to automotive grade, rugged and practical.
