1. Equipped with temperature compensation device for higher measurement accuracy

2. Suitable for different installation needs indoors and outdoors

3. selectAISI 304Stainless steel made sealed case

4. selectAISI 316Stainless steel made pneumatic connection components

5. The on-site display values and output signals are not affected by external factors such as altitude

6. Electric contact switch design, achieving precise and stableSF₆Gas density monitoring function

7. Up to four pairs of contacts can be used to achieve multiple options such as overpressure alarm, dual alarm, or dual locking, making monitoring safer and more reliable

8. Overlapping dial design eliminates gaps in the dial and avoids the impact of sunlight on the compensating components inside the watch;
