Model 1430 Microtector
Electronic Point Gage combines mod-
ern, solid-state integrated circuit elec-
tronics with a time-proven point gage
manometer to provide fast, accurate
pressure measurements.
SPECIFICATIONS AND FEATURES
• Accurate and repeatable to ± .00025
inches water column
• Pressure range: 0 - 2˝ w.c., positive,
negative, or differential pressures
• Non-toxic and inexpensive gage fluid
consists of distilled water mixed with
a small amount of fluorescein green
color concentrate
• Convenient, portable, lightweight
and self-contained, the unit requires
no external power connections and
is operated by a 1.5 volt penlight cell
• A.C. detector current eliminates
point plating, fouling and erosion
• Micrometers are manufactured in accor-
dance with ASME B89.1.13-2001, and
are traceable to a standard at the National
Institute of Standards and Technology
