Electrical testing
Refrigeration and air conditioning systems along with heat pumps are electrical systems and are therefore subject to electrical testing in some cases. Whether this involves multimeters, clamp meters, current testers or voltage testers – thanks to innovative technologies and simplified application, Testo’s measuring instruments measure electrical parameters safely and precisely.
Multimeters, clamp meters and voltage testers from Testo
testo 760 digital multimeter: Recognizes measurement parameters automatically
testo 770 clamp meter: Get a good grip on cables – even when things are tight
testo 750 voltage tester: Easy to read from any position
testo 755 current/voltage tester: A voltage tester that also measures current
testo 745 non-contact voltage tester: Filters high-frequency interference
One App for all applications.
The testo Smart App guides you quickly and easily through measurements on refrigeration, air conditioning and heating systems.

What I’d like to tell other technicians is that this instrument really saves a lot of time, and you don’t have to take that much stuff along, you’ve got less to do yourself because the testo 557s does everything for you.

We used to have to work with analog measuring instruments and needed a notepad, plus we needed external temperature probes. Testo has now incorporated all of that into one instrument. This makes it easier and much quicker for us to satisfy the customer with regard to the performance of their equipment.

My first impression is very positive; a very nice, new measuring set that you certainly won’t regret purchasing as a refrigeration technician. I don’t think any other brand can compete with it.
