Tianfang Technology has secured numerous national patents through the development of fingerprint locks, induction locks, and password locks. With advanced equipment and cutting-edge technology, the company's products remain at the forefront of the industry, offering high-performance, innovative smart lock solutions to users worldwide. Tianfang's strong technical foundation and creative approach have led the way in developing the "electromechanical conversion device" for intelligent locks, enabling a dual-choice unlocking system that prevents unauthorized access via mechanical keys.
Tianfang smart door locks offer the following advantages:
1. **Dual Electromechanical Conversion with Enhanced Security**
This system ensures that only an electronic key can unlock the door when the electronic system is functioning normally, while the original mechanical key becomes ineffective. In case of a power failure or malfunction, the mechanical key can be used, but the system will trigger an immediate alarm.
2. **Universal Compatibility**
There's no need to replace the entire mechanical lock. Simply replace the front and back panels to upgrade your existing security door into a high-tech anti-theft fingerprint lock.
3. **Wireless Video Intercom & Remote Unlocking**
You can view and communicate with visitors from anywhere in your home, and unlock the door remotely without having to physically go to the door.
4. **Instant Alarm System**
If someone attempts to tamper with the lock using a keyhole or other methods, the system will immediately trigger an alarm.
5. **Mobile Phone Unlock & Smart Alarm Integration**
You can unlock the door using your smartphone, and the system will automatically call a preset number if an unauthorized attempt is detected.
6. **Intelligent Network Management**
You can set access rights for specific individuals at certain times, review lock activity records, and even unlock the door remotely through a smart network.
7. **Semiconductor Biometric Identification**
The fingerprint lock uses advanced dermal recognition technology, ensuring a false acceptance rate of less than 0.0001% and a rejection rate of under 0.01%, making it highly secure against fake fingerprints.
8. **Combined Unlock Options**
Users can choose to unlock with a fingerprint, password, or both, maximizing security and flexibility.
9. **Randomized Password Function**
This feature helps prevent password theft by generating unpredictable sequences during input.
10. **Multiple Independent Opening Systems**
Including induction locks, fingerprint locks, and password locks, the system ensures safe and convenient access with at least two independent unlocking methods.
Additionally, the sky-proof lock offers four practical features: fingerprint unlocking, real-time monitoring, remote control, and wireless connectivity. It provides clear video transmission from the door to your room, allows remote locking and unlocking, and operates fully wirelessly for hassle-free use. As a patented product, Tianfang Lock adds an extra layer of security and convenience, enhancing daily life and helping people achieve a more secure and comfortable lifestyle.
Flow Calibration Column
Flow calibration column is widely used in flow calibration of metering pump and dosing device, which can accurately calibrate the output flow of metering pump. Flow calibration column is also called flow calibration tube, calibration column, calibration tube
Transparent tube material: plexiglass, transparent PVC,
Connector material: PVC, stainless steel,
Connection mode: internal thread, external thread and flange.
1. Overview
Flow calibration column is widely used in flow calibration of metering pump and dosing device, which can accurately calibrate the output flow of metering pump. Flow calibration column, also known as flow calibration tube, calibration column, calibration tube, the main material: plexiglass, transparent PVC and stainless steel; connection methods are internal thread, external thread, flange.
2. Selection of flow calibration column
The selection of flow calibration column is determined according to the requirements of pump flow and calibration time. For example, if the flow rate of the pump is 60L / h, and the customer needs to calibrate the flow rate of 0.5-1min, then the calculated flow rate per minute should be 60L â–³ 60 = 1L, then a calibration column with a volume of 1l can be selected.
3. Usage of flow calibration column
When using, the calibration column is filled with medium, and the liquid level of the medium is consistent with the maximum scale of the calibration column. According to the volume of the pump, open the pump volume, and then check whether the pump is calibrated according to the volume of the pump.
