Portable Pressure Calibrator  > Crystal IS33 Series

The smallest Crystals are shirt pocket size, but they're our
toughest yet with an unbreakable aluminum case. They're
our most versatile too, capable of measuring pressures
from "H2O all the way up to 3000 PSI and vacuum.

There are a variety of models to choose from. Model 31s
have one sensor, Model 33s have two. All sensors are
built-in, stainless steel, gas and liquid compatible, with an
accuracy of ±0.05% of reading. All models measure
milliamps (that can also be displayed in 0 to 100% for 4 to
20 or 10 to 50 milliamps), have an RS-232 port and come
with a carrying case. And, they're intrinsically safe.

Every 30 series instrument is tested and calibrated in an
environmental chamber, duplicating field conditions. That's
why the specifications (including milliAmps) are not derated
for temperature!

Last, but not least, a single 9V battery provides 90 hours
of continuous operation.
