The kit for app-controlled, wireless measurements and digital documentation on your smartphone. You will get the testo 550i app-controlled digital manifold with Bluetooth, 2-way valve block and sturdy hook. For wireless temperature measurement on either flow/return pipework or for superheat/subcooling calculation, the 2 x testo 115i Smart Probes supplied allow simple and effective measurement, and the testo 770-3 clampmeter can be used for compressor current measurenet and other electrical testing. You&rsquo;ll be ideally equipped to carry out your measuring tasks on either monobloc or split system Heat Pumps ,and the kit can also be used for general refrigeration and air-conditining service applications as well.

With this kit, you&rsquo;ll be ready to start your measurements in the commissioning, servicing and maintenance of &nbsp;heat pumps, refrigeration, or air-conditioning systems straight away: You will get the testo 550s smart digital manifold with Bluetooth and 2-way valve block, two testo 115i bluetooth temperature pipe clamp probes allow simple measurement of superheat and subcool values. The testo 770-3 clampmeter can be used for compressor current measurement, and completing the package is the testo 560i digital refrigerant scales for accurate and effective charging of refrigerants via weight.

With this kit, you&rsquo;ll be ready to start your measurements in the commissioning, servicing and maintenance of &nbsp;heat pumps, refrigeration, or air-conditioning systems straight away: You will get the testo 557s smart digital manifold with Bluetooth and 4-way valve block, two testo 115i bluetooth temperature pipe clamp probes allow simple measurement of superheat and subcool values whilst the testo 552i Vaccum smart probe provides bluetooth measurement during system evacuation procedure. The testo 770-3 clampmeter can be used for compressor current measurement, and completing the package is the testo 560i digital refrigerant scales for accurate and effective charging of refrigerants in conjunction with the Testo smart valve.

Start your wireless measurements on refrigeration and air conditioning systems and heat pumps straight away. The practical kit containing the testo 570s digital manifold with Bluetooth and 4-way valve block together with the wireless temperature and vacuum probes plus testo 770-3 clamp meter is ideal for long-term and standard measurements. The intelligent error analysis in the testo Smart App ensures reliable diagnostics following a long-term measurement, eliminating the need for lengthy searches. And with the world&#39;s longest battery life of 360 hours, testo 570s is ideal for long-term measurements, but also for all kinds of short-term applications over the course of a working week. In addition, with a measuring accuracy of 0.25% fs, the manifolds offer maximum precision even at low pressure values.
