Model SG-3 and Model SG-3A, consisting of a thermocouple gauge of low vacuum and an ion gauge of high vacuum, are a kind of direct reading vacuum measuring instruments. They can be widely used to measure the vacuum of the air system in laboratories or in factories.
Model SG-3A is the improved type of Model SG-3. In comparison with Model SG-3, it has the advantages of little zero drift, low temperature-rising, reliable function and so on.
These two models are installed in standard meter cabinets, universal in use and easy to be used on rack or bench.
