testo manifold top tip # 1
Analogue manifolds are basic gauges and will only measure high and low pressures. Additional measuring instruments are required for the determination of the refrigerant temperature, as well as for other measurement and testing tasks. All calculations and recording are done manually and, due to the limitations of the gauges and the difficulty of using several instruments to obtain a reading, the measurements are often approximate and inaccurate.
This is why digital manifolds are increasingly being used in the refrigeration trade. As they can record various operating parameters resulting in multiple measurements being taken simultaneously with higher accuracy, and all done by one instrument.
