Not every pressure point needs a reference-grade gauge, but every gauge in the field has to survive weather, drops, and long shifts. The Additel 680A is built for that work: a 304 SS shell, a fully welded sensor, an IP67 rating, and 10 g shock resistance, with 0.1% or 0.2% of full span accuracy and ranges up to 60,000 psi (4,200 bar).

The display stays clear in bright sunlight and switches to a white backlight with one button. Data logging stores up to 800,000 records, Bluetooth connects the gauge to the Additel Link app, and battery life reaches 4000 hours in the default mode. For hazardous locations, the ADT680AEx carries CLASS I, Division 1, Groups A, B, C and D, T4 and CLASS I, Zone 0, AEx ia IIC T4 Ga for North America. Do not connect to the RS232 port or replace batteries in hazardous areas.
