In industrial production, HVAC debugging, clean laboratory monitoring, and even medical equipment research and development, precise control of pressure parameters is like an "invisible hand", directly affecting equipment efficiency, environmental stability, and product quality. However, traditional pressure measurement tools often face problems such as insufficient accuracy, delayed response, and complex operation, especially in scenarios where small pressure differences need to be captured, making it difficult to meet the requirements.

1、 Why do we need a micro differential pressure gauge? ——Accurately capturing 'invisible pressure'

In many fields, pressure is not simply "high" or "low", but requires tiny differences precise to the level of pascals (Pa) or even millipascals (mPa). For example:

·Heating, Ventilation, and Air Conditioning (HVAC): The balance of air duct speed requires detection of a slight differential pressure of 0.1~10Pa to ensure uniform distribution of airflow;

·Cleanroom: To maintain a positive pressure environment, real-time monitoring of a pressure difference of 1-50Pa is required to prevent external contamination from entering;

·Industrial equipment: Filter blockage warning needs to capture pressure difference changes of 20-200Pa to avoid faults in advance;

·Medical respiratory equipment: Airway pressure monitoring should be accurate to ± 1Pa to ensure patient safety.

Traditional pressure gauges or ordinary differential pressure gauges are limited by accuracy and response speed, often unable to meet the requirements of these scenarios. The emergence of GTI113 is precisely to fill this gap - it is designed specifically for measuring small pressures, making "invisible pressures" clear and controllable.

2、 The core advantages of GTI113: precision, flexibility, and reliability

As a handheld micro differential pressure gauge designed specifically for professional scenarios, the GTI113 aims to "solve practical pain points" in terms of accuracy, functionality, and user experience. Its core advantages can be summarized into three points:

1. High precision measurement, accurate in millimeters

GTI113 adopts a high-sensitivity piezoresistive sensor with an accuracy of ± 0.5% ± 0.5Pa and a resolution of up to 0.1Pa. Whether it is detecting small air velocity differences in HVAC ducts or monitoring pressure fluctuations in clean rooms, it can provide stable and reliable values to avoid misjudgment caused by errors.

2. Multi functional integration, one device covers multiple scene requirements

Unlike single function measurement tools, GTI113 integrates three major functions of "differential pressure measurement+wind speed calculation+temperature monitoring" to meet the diverse needs of various scenarios:

·Differential pressure measurement: supports positive pressure, negative pressure, and bidirectional pressure difference detection, with a range coverage of ± 500Pa;

·Wind speed and air volume calculation: With a pitot tube and built-in algorithms, the differential pressure value can be directly converted into wind speed (m/s) and air volume (m3/h) without the need for additional equipment, improving HVAC commissioning efficiency;

3. Humanized design makes measurement simpler

GTI113 optimizes design details based on actual user operation scenarios:

·Handheld and portable: The body weighs only 363g, with a small size that can be held with one hand, suitable for long-term on-site operations;

·Clear display: high-definition LCD color LCD screen, multiple pressure units can be switched (inH2O/mmH2O/Pa/mmHg), data can be directly browsed and statistically analyzed, and data changes are clear at a glance;

·Fast response: The sensor response time is less than 1 second, which can capture instantaneous pressure fluctuations and avoid missing key data;

·Long battery life: Equipped with 4 built-in No. 5 dry batteries, it can last for more than 15 hours when fully charged, meeting the needs of all-weather operation.

3、 Real world application: How does GTI113 solve industry pain points?

From research and development laboratories to production lines, GTI113 has been widely used in multiple fields, becoming a "capable assistant" for professionals:

Case 1: HVAC system debugging - making wind speed balance "visible"

The HVAC engineer of a commercial complex needs to ensure that the wind speed of the air ducts on each floor is uniform (with a deviation of less than 10%) when debugging the fresh air system. The traditional method requires repeated measurement of wind speed and calculation of pressure difference, which is time-consuming and prone to errors. After using GTI113, engineers can directly read the pressure difference of the air duct through the device and display the wind speed value directly. Within 10 minutes, the entire layer of wind speed balance detection can be completed, and the efficiency can be improved by 80%.

Case 2: Cleanroom pressure difference management - the "invisible defense line" to protect the production environment

A pharmaceutical factory requires a positive pressure difference of 5-10 Pa to be maintained between different areas in the clean room to prevent external pollution. In the past, it relied on regular manual testing, and data could not be directly saved and read, making calculations very cumbersome. After the introduction of GTI113, technicians can monitor the pressure difference in various areas in real time and export historical data through the device storage function, which not only saves manpower but also improves compliance.

Case 3: Industrial equipment maintenance - early warning to avoid downtime losses

The air compressor system of a certain factory needs to regularly check the filter pressure difference (normal value<150Pa). If the pressure difference is too large, it will prompt blockage and need to be replaced. In the past, due to the lack of precise tools, equipment energy consumption increased or even shut down due to delayed judgment. After using GTI113, maintenance personnel can quickly detect the pressure difference daily, and replace the filter element in advance when the value approaches 150Pa, reducing the annual maintenance cost of a single device by about 30%.

4、 Choosing GTI113 means choosing professionalism and peace of mind

In the era of pursuing efficiency and quality, precise measurement is the core manifestation of professional ability. The GTI113 handheld micro differential pressure gauge, with "high precision, multifunctionality, and easy operation" as its core, provides a reliable micro differential pressure measurement solution for HVAC, clean, industrial, medical and other fields.

Whether it is a pharmaceutical factory that requires strict environmental control, a data center that pursues energy efficiency optimization, or a factory workshop that needs to ensure stable equipment operation, GTI113 can become your "pressure measurement expert".
