ISO temperature calibration certificate for surface probes; with 1 measuring point: +60 &deg;C

With this kit, you’ll be ready to start your measurements in the commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps straight away: You will get the testo 550s smart digital manifold with Bluetooth and 2-way valve block, two fixed cable clamp temperature probes (NTC) and a robust transport case. Additional Bluetooth probes, e.g. for wireless measurements of temperature and vacuum, are available separately.

The testo 550s digital manifold with Bluetooth and a 2-way valve block features a large graphic display, a compact, robust housing, guided measurement menus and the testo Smart App. Top-quality measurement technology, a high degree of reliability and smart functions for quick, easy measurements and documentation make the testo 550s manifold a reliable partner for your commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps.

The kit for wireless measurements in the field of commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps: You will get the testo 550s smart digital manifold with Bluetooth and 2-way valve block, two testo 115i wireless clamp thermometers (Bluetooth, NTC) and a robust transport case. Additional Bluetooth probes, e.g. for wireless, hose-free vacuum measurements with the testo 552i, are available separately.

Additional Bluetooth probes, e.g. for wireless, hose-free vacuum measurements with the testo 552i, are available separately.

The testo 557s digital manifold with Bluetooth and a 4-way valve block features a large graphic display, a compact, robust housing, guided measurement menus and the testo Smart App. Top-quality measurement technology, a high degree of reliability and smart functions for quick, easy measurements and documentation make the testo 557s manifold a reliable partner for your commissioning, servicing and maintenance of refrigeration and air conditioning systems and heat pumps.

Start your wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. Thanks to the Bluetooth vacuum probe supplied, you can even measure vacuum without any cables or hoses. You will get the testo 557s smart digital manifold with Bluetooth and 4-way valve block, one testo 552i wireless vacuum probe (Bluetooth), two testo 115i wireless clamp thermometers (Bluetooth, NTC) and a robust transport case. For other wireless measurements, other optionally available testo Smart Probes are also ideal.

For completely wireless measurements on refrigeration and air conditioning systems and heat pumps. Thanks to the Bluetooth vacuum probe supplied, you can even measure vacuum without any cables or hoses. You will get the testo 557s smart digital manifold with Bluetooth and 4-way valve block, one testo 552i wireless vacuum probe (Bluetooth), two testo 115i wireless clamp thermometers (Bluetooth, NTC), a hose filling set with 4 hoses and a robust transport case. For other wireless measurements, the Testo Smart Probes are ideal.

Use the fixed cable clamp probe (NTC) to accurately measure surface temperatures on heating system pipes, water pipes, refrigeration systems or heat pumps (pipe diameter 6 to 35 mm). Depending on the connected measuring instrument, the robust clamp probe can be used to detect superheating/subcooling on refrigeration systems, but also to determine flow and return temperatures in heating technology, for example. The collet enables the surface probe to be attached quickly and easily.

Ideal for calculating superheating/subcooling on refrigeration and air conditioning systems and heat pumps: Use the clamp probe kit for fast, accurate surface temperature measurements on pipes with diameters of 6 to 35 mm. The probe’s fixed cable has built-in kink protection – making it exceptionally robust and break-proof.
