Digital pressure gauge as312 model : as 312 temperature : -10 to 50°c range : 0 to 700 bar battery life : 2000 hours accuracy : ± 0.5% of f.s output : nil description : the as312 series is a media isolated digital pressure gauge featuring multiple measurement units, minmax readings, selectable tarezero 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. specifications : display update rate : 2 samples per second power : 9 volt alkaline battery automatic power off : 1 hour battery life : 2000 hours operation (typical) protection rating : nema 4, ip 65 instrument case poly carbonate performance @ 25°c (77°f) : pressure range : a number of preset ranges are available measurement units : psi, bar, kgcm, atm, inh20, inhg accuracy : hysteresis and non-repeatability) stability (1 year) : ±0.25% fs (typical) over range protection : 2x rated pressure burst pressure : 5x or 20,000 psi whichever is less pressure cycles : >100 million environmental data temperature media : -55 to 125°c (-67 to 257°f) operating (ambient) : -10°c to 70°c (14°f to 158°f) storage : -10°c to 85°c (14°f to 185°f) thermal limits compensated range : 0°c to 55°c (32°f to 131°f) tc zero : tc span :
