The testo 512-1 is a differential pressure gauge equipped with a high-precision differential pressure sensor. It is ideal for measuring inter-room differential pressure in clean rooms, checking negative pressure during asbestos removal work, and inspecting pressure in combustion equipment. When combined with an L-shaped Pitot tube, it allows for the calculation of wind speed and airflow from differential pressure (dynamic pressure). It is best suited for measuring in high wind speed ranges (40 to 100 m/s), high temperatures (70 °C and above), and ducts containing dust and mist. The testo 512-2 is a differential pressure gauge capable of measuring differential pressure and gauge pressure up to 2000 hPa. 【Features】 ■ Backlight ■ Hold function ■ Maximum/Minimum values ■ Average (time/multiple points) ■ Damping ■ Auto-off ■ Sound alarm ■ Printer (optional) ■ Mobile app integration ■ Wind speed and airflow calculation (512-1) *For more details, please download the PDF or feel free to contact us.

The testo 440dP is a multi-environment measuring instrument that allows for environmental measurements with a single device by attaching probes. It has a built-in differential pressure sensor, making it suitable for adjusting ventilation and air conditioning systems, measuring comfort levels indoors, and assessing filter effectiveness in clean rooms. It features a built-in menu for environmental measurements, allowing for intuitive operation. There is a wide variety of digital probes available, including both wired and wireless types, which can be selected according to the application. 【Features】 ■ Simple menu structure for intuitive operation ■ Clearly displays three parameters on a color display ■ Calculates air velocity/flow from differential pressure measurements ■ Built-in memory for saving data in CSV format *For more details, please download the PDF or feel free to contact us.

The testo 420 differential pressure gauge is a convenient device for checking the effectiveness of dust filters in clean rooms. It can also calculate air velocity and airflow in air conditioning ducts using a Pitot tube. 【Features and Functions】 ■ Differential pressure gauge suitable for micro differential pressure measurement ■ 3.5-inch large screen display ■ Maximum and minimum value display ■ Memory included (continuous recording possible for up to 15 minutes), can be connected to a PC ■ Air velocity calculation ■ Connect a Pitot tube to the main unit for air velocity calculation ■ Automatic zero adjustment function to prevent zero point drift *For more details, please download the PDF or feel free to contact us.

The "testo 550i" is a lightweight and compact manifold that does not have a display and is designed for app operation only. By simply turning on the device and launching the "testo Smart" mobile app, it automatically connects via Bluetooth, allowing you to start using it quickly. Additionally, we also offer the smart scale "testo 560i," which can be easily operated from the digital manifold or mobile app. 【Features and Functions】 ■ Lightweight at 595g ■ Selectable from over 90 types of refrigerants (R32, R410A, R463A, R407C, R448A, R600a, R290, R134a, R22, etc.) ■ Simultaneous display of pressure, saturation temperature, temperature, superheat, and subcooling ■ Versatile for tasks such as vacuuming, refrigerant charging, commissioning, and regular inspections ■ App integration for recording, documenting, and sharing measurement results *For more details, please download the PDF or feel free to contact us.

The "testo 550s/557s" is a digital manifold that excels in various applications such as vacuum pumping, refrigerant charging, trial operation, and regular inspections. Not only can it accurately measure refrigerant pressure, but it also displays the saturation temperature (evaporation temperature and condensation temperature) according to the selected refrigerant. When a temperature probe is connected, it can calculate superheat and subcooling. It connects wirelessly to a smartphone, allowing for the recording and documentation of measurement results. With the use of optional features, you can utilize vacuum mode and automatic charging mode. 【Features and Functions】 ■ Selectable from over 90 types of refrigerants (R32, R410A, R463A, R407C, R448A, R600a, R290, R134a, R22, etc.) ■ Simultaneous display of pressure, saturation temperature, temperature, superheat, and subcooling ■ Large display with backlight that supports Japanese language display ■ Versatile use for vacuum pumping, refrigerant charging, trial operation, and regular inspections ■ App integration for recording, documenting, and sharing measurement results *For more details, please download the PDF or feel free to contact us.
