Functions of Testo’s digital manifolds
Testo’s digital manifolds are powerful tools that offer refrigeration, air conditioning and heating engineers maximum efficiency and precision. Equipped with advanced features specifically designed for demanding work environments, they are indispensable companions in the field of system maintenance and diagnostics. Here are the key features that make the manometers true all-rounders:
These manifolds combine the advantages of a touchscreen with those of a traditional keypad. This combination enables intuitive operation for quick measurements, while the keypad operation remains reliable in adverse conditions, such as wet conditions or when working with gloves. Wireless integration into the entire Testo refrigeration portfolio also offers flexible and versatile use in any situation.
With a measuring accuracy of 0.25% over the entire range (up to 60 bar), the manometers deliver accurate results. Built-in temperature compensation ensures that external influences do not distort the readings. In addition, the compatibility of the manifolds with A3 and A2L refrigerants ensures maximum safety when working with environmentally friendly but flammable refrigerants.
Thanks to the hybrid charging system, which supports both non-rechargeable and rechargeable batteries (via USB-C), the manifolds are always ready for use – no matter where you are. The rugged design with IP54 protection ensures durability even in the harshest conditions. Regular over-the-air (OTA) updates keep the manometers up to date without the need for additional software installations.
The Bluetooth range of up to 150 metres and seamless integration into the testo Smart App enable remote control and monitoring of your measurements. All data is recorded in real time and can be documented and shared directly via the app, making workflows more efficient and professional.
Applications of digital manifolds
Digital manifolds are essential tools for installers and refrigeration and heating engineers, also known as HVAC/R technicians. These professionals use the manometers to ensure precise diagnostics and energy efficiency of refrigeration, air conditioning and heat pump systems. The innovative technology and smart features of the manifolds offer numerous advantages that make life much easier for technicians.
One key application for digital manifolds is the precise determination of high and low pressure in the refrigeration circuit. All results are displayed simultaneously on a large graphic display, allowing technicians to see immediately whether the system is functioning correctly. This enables quick and efficient diagnosis of the system.
Another important application is leak testing. Testo’s digital manifolds precisely record and analyze the pressure curve to check the tightness of systems. This function is crucial for detecting leaks, ensuring system efficiency and preventing environmental damage. Precise recording and analysis of the pressure curve enables technicians to quickly identify and repair potential leaks.
In conjunction with suitable measuring instruments such as the testo Smart Probes, our digital manifolds can automatically calculate the target superheat and subcooling. This saves time and increases the accuracy of the setting, thereby improving the efficiency of the system. Compared to analog manometers, our digital solutions also offer temperature compensation to ensure truly reliable results.
Measuring the vacuum and evacuating systems are necessary tasks when installing refrigeration and air conditioning systems, in order to remove moisture and foreign gases from the system. Digital manifolds provide a graphical progression display of the pressure values and the evacuation process. When used in conjunction with the appropriate testo Smart Probes, such as the testo 552i vacuum probe, technicians can run the evacuation process fully automatically thanks to the auto-stop function when target vacuum values are reached. Together with the self-starting vacuum hold test, this makes it possible to carry out fully automated evacuation.
Long-term measurements can be carried out for a detailed inspection of systems. Testo’s digital manometers enable technicians to take measurements over longer periods of time and analyze the data collected. With long-term measurements of up to 72 hours, each reading can be diagnosed and potential problems can be detected early. This is particularly useful when plant operators report faults that cannot be immediately reproduced on site. Long-term measurements enable technicians to take targeted action, resulting in improved plant performance and reliability.
What to look out for when buying a digital manifold
Selecting the right digital manifold is crucial when it comes to ensuring that you work accurately and efficiently in the refrigeration, air conditioning and heating industry. With so many models to choose from, there are a few important things to consider to help you choose the best manometer for your needs.
In measuring technology, precision is key. Make sure that the manifold has high accuracy and built-in temperature compensation to ensure reliable results in different environmental conditions. An accuracy of 0.25% over the entire measuring range (60 bar) is a good benchmark for a professional manometer.
A good manifold should ideally be equipped with both a touchscreen and a keypad. This enables flexible use, particularly in difficult working environments in which you may have to wear gloves or use the instrument in wet conditions. Models that also offer wireless control and documentation via an app provide even more flexibility and efficiency.
One key purchasing criterion is the manometer’s compatibility with modern refrigerants such as A3 and A2L, which are increasingly being used because of their environmental friendliness.
A digital manifold that receives regular over-the-air (OTA) updates offers a significant advantage. This means you always have the latest technology at your fingertips, without the additional cost of new equipment or software. This guarantees that your instrument is future-proof and remains compatible with new refrigerants and features.
The manifold should be rugged and durable, to withstand the toughest working conditions. Look for an IP54 certification, which provides protection against dust and spray water.
