Buying advice

When choosing a vacuum gauge, consider the pressure range you need, whether you prefer analog or digital readouts, and the importance of portability versus robustness. For general laboratory use, a capacitive manometer like the MKS 626A offers the best accuracy, while the Omega HG-10B provides a cost-effective solution for routine monitoring. If you work primarily in low-vacuum regimes, a Pirani-type gauge such as the Vacuubrand VP2 or MKS 241A will give reliable performance. Dual-mode gauges give the most flexibility but can be more complex to install and calibrate.
