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