From the manufacturer
Testo was founded in Lenzkirch, in the Black Forest region of Germany, in 1957 and has since designed, developed, and manufactured portable test and measurement instrumentation and solutions. Backed by 60 years of measuring engineering experience, testo’s mission is to provide the highest quality, service, and value in the industry.
Testo’s first product manufactured was a simple electronic thermometer. Today, the product line has expanded to include a large variety of temperature measuring instruments, such as data loggers, air velocity meters, humidity and dew point meters, refrigeration service analyzers, multifunction instruments, stack gas analyzers and air emission monitors, water analyzers, tachometers, sound, pressure, and light meters, and thermal imagers.
Accuracy and flexibility on site with the testo 557
With its 4-way valve block, large backlit display, sight glass, two NTC thermistor clamp probes and vacuum gauge the testo 557 combines convenience with the the superior accuracy of a digital gauge to provide you with accurate readings for every job.
Convenient and Precise
The rugged, compact design allows you to take the testo 557 to onto any job site and readings are shown on the large, easy to read 2-line backlit display within seconds. The 60 on board refrigerant profiles eliminate the need for PT charts.
Complete Servicing Kit
Your testo 557 Kit includes 4 hoses, each 5 ft long: 3 hoses (blue, red, yellow) with 7/16‘‘ UNF (straight and 45° angle), 1 Hose (yellow) with 5/8‘‘ UNF, (straight and 45° angle), suitable for all refrigerants. No need to switch over refrigerant hoses thanks to automatic heat pump mode.
Highlights
- Measures high side / low side pressure and displays saturation / evaporation temperatures
- 2 temperature probe inputs for simultaneous real-time calculation of superheat and subcooling
- External vacuum probe for faster and more reliable evacuation of the system
- Automatic heat pump mode eliminates the need for switching refrigerant hoses
