Electronic Vacuum Meter Testo 552
Testo
Electronic Vacuum Meter Testo 552
Art. no.: 7066456
Testo 552 is a digital vacuum reader for vacuum suction of cooling systems and heat pumps. It measures very low absolute pressure values and provides extremely accurate information about the system's dehumidification status (removal of foreign matter, including oils, foreign gas, etc.). Via a Bluetooth interface, testo 552 can connect to the testo SmartProbes app on your smartphone or tablet. It allows monitoring of the absolute pressure value obtained during vacuum suction - conveniently and wirelessly. In addition, measurement results can be quickly documented in the app and sent by email. The robust construction makes it ideal for everyday use and protects it from dirt and water.
Battery time: 50 hours without Bluetooth / backlight)
Compatibility for the SmartProbes app requires iOS 8.3 or later / Android 4.3 or later. It also requires a mobile device with Bluetooth 4.0

Temperature Logger in mini format IP65 - Testo
Art. no.: 4234665
Testo 174T
Display with current measured values and measuring information. Retains stored measurement data during power outages. The Testo 174T logger can be used almost everywhere where temperatures need to be registered
and documented. Perfect for, e.g., checking of various types of premises, or verification that a cooling or freezing chain has not been broken.
Also suitable for monitoring of spaces where temperature-sensitive products are stored and handled.
The data logger with display shows the most recent measured value and the maximum and minimum values directly at the measurement location.
Also shows if limit values have been exceeded. With the user-friendly, Swedish-language ComSoft4 software, data and settings can be transferred to a desktop or laptop PC.
The software can be downloaded from Nordtec’s Web site.
*THE BASIC MEASUREMENT SET INCLUDES: USB interface, logger 174T, wall holder, battery, and calibration protocol.

The Testo 174H model measures temperature and humidity, -20 to 70°C and 0 to 100 %rh.

Vacuum Pump Class A1, A2, A2L & A3
Testo
Vacuum Pump Class A1, A2, A2L & A3
Art. no.: 75897865
The new testo 565i vacuum pump performs vacuum extraction of refrigeration systems and heat pumps completely automatically thanks to the connection to the testo 552i vacuum sensor. When the desired vacuum target value is reached, the pumping stops automatically and a vacuum hold test starts simultaneously. This safely removes foreign gases and moisture, and information about the system's tightness is saved. The data logging function ensures complete documentation. This allows vacuum extractions to be carried out entirely independently.

Configuration, monitoring of real-time values, and sending of measurement reports can be easily managed via the free testo Smart App. This makes you flexible and saves valuable time.

For an optimal workflow, the testo 565i automatically establishes a Bluetooth connection to Testo's refrigeration gauges and to the testo Smart App when it is started. The pump also guarantees maximum safety at all times thanks to its compatibility with A2L and A3 refrigerants.

The testo Smart App guides you quickly and easily through measurements on refrigeration, air conditioning, and heating systems.

*Automatic Bluetooth® connection to your mobile and to the testo Smart App
*Preliminary setting for vacuum extraction
*Monitoring of all measurement values and data storage
*Graphical progress display
*Create and send measurement reports

Testo 557s Measure Set
Testo
Testo 557s Measure Set
Art. no.: 4234675
The digital manometer stand testo 557s with 4-way valve block allows fast measurements on cooling units, air conditioners and heat pumps. The large display also helps you analyze the results in graphic form. Finished program functions guide you through the measurement and enable automatic calculation of many important system parameters such as overheating, pressure drop testing or emptying. Thanks to the Bluetooth vacuum sensor testo 552i included in the measuring set, testo 557 can - as the first manometer stand ever - used for wireless vacuum measurement. Bluetooth sensors for temperature, pressure and humidity can be easily connected directly to the instrument and offer maximum flexibility. In combination with the testo Smart app, you can handle the digital documentation directly at the measurement site. In addition, you always have the current refrigerants available and can set your favorites and transfer them to the instrument. The proven quality and high durability guarantee that your manometer stand always delivers high performance, in all circumstances.

Temperature Meter Testo 922
Testo
Temperature Meter Testo 922
Art. no.: 67230858
There is a reason why professionals in industry and trade appreciate the compact differential temperature meter testo 922: it not only determines temperatures quickly and accurately but also directly calculates the differential temperature. And it does so within a wide measurement range – from -50 °C to +1000 °C. A typical application for the testo 922 is, for example, measuring supply and return temperatures. Two type K thermocouple sensors are included. The testo 922 is also compatible with other type K wire sensors on the market.

Here's how the testo Smart App makes things easier for you:
Simple setup of the measuring instrument
Efficient customer and measurement site management
Reliable storage of all measurement data
Transforms your mobile phone into a second screen
Displays graphical measurement value curves

D-Tek Stratus Electronic Leak Detector with Infrared Sensor
Inficon
D-Tek Stratus Electronic Leak Detector with Infrared Sensor
Art. no.: 7070191
D-TEK Stratus is the top model of Inficon's electronic leak detector that makes it easier than ever to find refrigerant leaks of all kinds in no time. D-TEK Stratus has two modes, a Cloud Hunting mode and a pinpoint mode. The Cloud Hunter mode is optimal to use in rooms with a lot of refrigerant gas in the air by showing the concentration of refrigerant gas in ppm on the leak detector's large color display.The closer you get to the source of the leak, the higher the concentration is displayed. The pinpoint mode is optimal to use when you are close to the leakage point as the leak detector in the classic way alerts for leakage with a color scale from green to red and a ticking sound with a frequency that indicates the concentration of the refrigerant gas. Switch between automatic and manual reset. The D-TEK Stratus has a newly developed IR sensor with the longest durability on the market that is easy to replace. Comes with lithium-ion battery, AC charger, DC charger for car, spare filter, IR sensor, headphones, extra long probe and impact-resistant bag.
Whisper Electronic Leak Detector with Ultrasound
Inficon
Whisper Electronic Leak Detector with Ultrasound
Art. no.: 22070806
Whisper is an electronic leak detector ideal for detecting and locating ultrasonic frequencies generated when the following common situations occur:
• leakage of any gas under pressure or vacuum
• electrical overload
• worn bearings
Whisperer picks up the ultrasound that arises in the event of, for example, leakage and turns it into an audible sound for the human ear in the supplied headphones. In this way it is possible to locate the leakage of whichever refrigerant or other gas at any time, for example when a conventional leak detector or leak detection spray does not work so well. Because the Whisperer only takes up ultra frequency sound it works really well, even in noisy environments. Supplied with a hard plastic bag and two “D” alkaline batteries, which can provide 165 hours of operation.
