with this innovation is to save its customers a lot of time while maximising efficiency.
Wireless connectivity and remote control via smartphone Efficiency and flexibility are essential in times of skills shortages. Testo relies on this, too. Workflows are optimised through end-to-end connectivity between the devices. This means that evacuations can also be monitored remotely.
For most people, the smartphone is not only a constant companion, but also a tool to control more and more technical devices. The testo Smart App allows the entire evacuation process to be controlled by smartphone and all the collected data to be saved or sent as a measurement report. This ensures maximum flexibility and ease of use for the customers.
Increasingly important: compatibility with flammable refrigerants
The growing demand for climate-neutral solutions means that flammable refrigerants are becoming increasingly important and being used more and more often. To be prepared for modern refrigeration systems and heat pumps, Testo guarantees that its new vacuum pump can be used safely even with flammable class A3 and A2L refrigerants.
Reliability and convenience Testo also places emphasis on safety with its integrated nonreturn valve; this prevents vacuum loss even in the event of power interruptions thereby guaranteeing a high level of reliability.
To ensure that vacuum pumps work smoothly, oil must be topped up regularly and the oil level checked. To save time in this area too, a large sight glass allows the oil level to be assessed quickly and the oil to be added and removed easily.
