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.
