Look no further if you are after an absolute bargain for your next set of digital gauges.
The Testo 557 digital refrigeration gauge has a 4-way valve block, a large backlit display, and sight glass. Two NTC thermistor clamp probes provide superior accuracy of simultaneous, real-time superheat and sub-cooling readings. An external vacuum probe provides fast and more reliable evacuation of the system.
If you add up the cost of buying all those instruments individually, you can see why it makes sense to own this amazing piece of kit.
The gauges allow you to connect via Wireless Bluetooth to a Testo App, which allows you to view measurement data on your Smartphone or Tablet and quickly complete and save all data corresponding to your job. You can then email the service reports and invoice from the job site to your customer.
In addition to the 60 refrigerant profiles stored in the instrument, the App can also be used to download new refrigerants from the Internet directly into the digital manifold.
