Microtector portable Electronic Point Gage
(전자식 포인트 게이지)
Accuracy ±0.00025" W.C.  Battery Operated, Self-Contained


 Model 1430

Meets laboratory and field needs for fast, accurate pressure measurements at moderate cost. Combines modern, solid state integrated circuit electronics with time proven point gage manometer. Delivers repeatable accuracy in measuring positive, negative or differential pressures to ±.00025" water column over a 0 to 2" w.c. range. Metric model M-1430 reads from 0-50 mm w.c.

Calibrates other instruments. Provides high precision for test laboratories of manufacturers of fans, air conditioning and heating equipment, pneumatic or fluidic controls, etc. Used in college, university and consultant laboratories - wherever precision measurements are required. Used with pitot tube (at extra cost) for precision measurement of low air velocities.

Measures positive, negative or differential pressures to 2/0" W.C. When pressure is applied, fluid level frops in left bore, rises over point in right bore, actuating meter. Point is then retracted from fluid, returned again slowly until contact registers on meter. Reading on micrometer is then noted. Repeat operation several times. Then multiply average by two. This is the pressure applied. Interpolating eight divisions between .001 micrometer graduations easily achieves a -total accuracy of .00025" w.c.

Simple, detailed instructions furnished enable operator to level unit, adjust fluid level and zero gage quickly. To level, adjust finger-tip screws in base, using spirit level bubble as guide. To bring fluid to proper height in bore, open rapid shut-off valve tube connectors. Back point out of fluid. Remove or add fluid until it coincides with mark on bore.

To zero gage, set micrometer scales at zero mark. Turn meter switch on. Turntop micrometer knob to lower the point until meter indicates contact. Readjust until zero micrometer reading and meter contact indication exactly coincide. Gage is ready for use.

 Easy to Maintain and Clean

Battery replacement and instrument cleaning are quick and simple - use mild soap and water. Indicating fluid consists of distilled water and a small amount of Dwyer A-126 Fluorescein green color concentrate. Max. pressure 100 psig (6.89 bar).
