Description

The AS312 series is a media isolated digital pressure gauge featuring multiple measurement units, min/max readings, selectable tare/zero and an automatic power
off to conserve battery power. Also, a backlight provides improved visibility under marginal lighting conditions.

The AS312 will operate with any liquid or gas that is compatible with 17-4PH stainless steel. Please consult the factory for other available wetted materials.

The design of this one-piece sensing element contains no silicone oil, welds or internal O-rings. The AS312 is ideal for oxygen service, hydrogen* tanks and other critical applications where fluid filled gauges cannot be used.
