New Testo 549 – Our best ever value manifold

The biggest strength of the Testo 549 digital manifold has to its phenomenal value. At under £200 it is our best ever value manifold. Just switch on, measure, and read off Large figures allow the values to be read off the display quickly and easily.



Testo's new manifold range are incredible value, completely negating the price advantage of analogue gauges


Two temperature-compensated pressure sensors measure high and low pressure quickly and precisely, and automatically calculate the temperatures. A glance at the instrument display is enough, and you see the measurement result. Two temperature inputs guarantee you the simultaneous calculation and display of superheating and subcooling. The temperature can additionally also be displayed. By simply pressing a button, you can switch between the measurement tasks at your will.



 No matter how tough the job is, testo refrigeration manifolds are be up to the task
