The testo 552 is a high-precision digital vacuum gauge designed to provide you with absolutely reliable readings. It has all the measuring functions you need for evacuating refrigerant systems and heat pumps and is built to last and tough enough to take the odd knock
Users can read the measurements using the testo Smart Probes App installed on their smart device. The testo 549i easily connects to standard Schrader valves without tools and without hoses,eliminating any refrigerant loss.
The Testo 549 digital refrigeration gauge is a breakthrough value, making analog gauges obsolete. It precisely measures high side / low side pressure and instantly displays the corresponding saturation / evaporation temperatures for 60 refrigerants
The testo 526-2 high-precision differential pressure measuring instrument is ideally suited for checking pressure in sensitive industrial processes, thanks to a measuring accuracy of ± 0.05% of final value.
Small, handy and practical: the testo 511 absolute pressure meter measures absolute pressure and is also suitable for measuring the barometric altitude between two points.
Handy and intelligent: the compact testo 510i differential pressure measuring instrument featuring professional measuring technology and smartphone operation for measuring differential pressure, air flow velocity and volume flow
