A digital manifold gauge has been released that has a high pressure pressure gauge and a composite pressure gauge attached, allowing you to quickly check the pressure, temperature, superheat, and subcooling in real time when charging or draining refrigerant, allowing you to quickly confirm whether the refrigerant is being charged.

Testo Korea (Branch Manager Jeon Kyeong-ung), the Korean branch of Testo, a world leader in measurement technology, announced on the 7th that it will be introducing the digital manifold gauges 'testo 557s' and 'testo 550s' to help refrigeration engineers perform gas measurement tasks for refrigerant management more easily and conveniently.

A digital manifold gauge is a device that is used to charge or drain refrigerant, with a high pressure pressure gauge and a combined pressure gauge attached. It checks pressure, temperature, superheat, and subcooling in real time, allowing you to quickly check whether the refrigerant is being charged.

'testo 557s' is a digital manifold gauge with 4-way valve block for commissioning and maintenance management of refrigeration systems and heat pumps.

All measurement data and evaluation results are clearly presented digitally via a large graphic display, and all measurement data and evaluation results can be wirelessly transmitted to Testo's dedicated mobile app.

The measurement menu is guided while measuring, and important variables can be automatically recorded.It supports Bluetooth up to a range of 100m, so you can check the measured values in real time through a smartphone connected via Bluetooth. You can also conveniently manage the refrigerant through the app using favorites and automatic updates.

It also has an international waterproof and dustproof protection rating of IP54, protecting the product from water and dust, allowing safe operation in harsh working environments, and is equipped with various functions that facilitate routine work on refrigeration systems and heat pumps. Supplied as a practical kit, users can immediately prepare for all measurement tasks in optimal condition.

'testo 550s' is a digital manifold gauge with a 2-way valve block for commissioning, repairing and maintaining refrigeration systems and heat pumps. Like the 'testo 557s', it can evaluate results in graph form via a large Korean display.

The stored program guides the user through the measurement process, automatically measuring critical system parameters such as superheat/subcooling, target superheat, cooling/heating capacity and several other areas.

All measurement data and evaluation results can be wirelessly transmitted to Testo's dedicated mobile app, and the product has obtained the international water and dust protection rating of IP54, protecting it from water and dust, so it can be used even in harsh working environments. It can wirelessly measure humidity, temperature and vacuum in real time and record data by linking with a mobile app via Bluetooth 5.0.

“The ‘testo 557s’ and ‘testo 550s’ are products that make commissioning, repair and maintenance of refrigeration systems and heat pumps much easier for maintenance engineers of heating and cooling facilities. Their 4-way and 2-way block methods support fast and efficient work, respectively,” said Sangyeop Lee, HVAC/R Sales Manager at Testo Korea. “With the upcoming season of rapidly increasing refrigerant use ahead, these products allow engineers to work more conveniently and safely on-site via Bluetooth and a dedicated app, and are optimized for demanding measurement tasks in various industrial sites.”

Meanwhile, Testo Korea is the Korean branch of Testo SE & Co.KGaA, a global measuring instrument company established in 1957 in Germany, and provides smart measurement solutions for various industrial sites. Testo has maintained an average annual growth rate of more than 10% and is striving to develop measurement solutions that will lead the Industry 4.0 era. In addition, since the establishment of the Korean branch, it has been the first in the industry to have a domestic service center and has been realizing customer satisfaction through after-sales service and technical support.
