Installation and Operating Instructions

Model 1430 Microtector

®

Portable 

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

•  

Three-point mounting, dual leveling 

adjustment, and circular level vial  
assure rapid setup

•  

Durablock precision-machined acrylic 

plastic gage body

•   

Sensitive 0 - 50 microamp D.C. meter 

acts as a detector and also indicates 
battery and probe condition 

•   

Heavy 2˝ thick steel base plate

provides steady mounting

•   

Top-quality glass epoxy circuit board 

and solid-state, integrated circuit 
electronics

•  

Electronic enclosure of tough, molded 

styrene acrylonitrile provides maximum 

protection to components yet allows     
easy access to battery compartment

•   

Rugged sheet steel cover and carrying 

case protects the entire unit when not 
in use

•   

Accessories included are (2) 3-foot 

lengths Tygon tubing, (2) 1/8˝ pipe 
thread adapters and 3/4 oz. bottle of 

fluorescein green color concentrate 

with wetting agent

Maximum pressure: 100 psig with
optional pipe thread connections.
