The MC Miller Co., Inc. is now manufacturing the Gas Electronics Model 702 Underground Insulation Checker, a patented corrosion test instrument, utilizing electrochemical reaction to perform 100% accurate insulation tests on all types of buried insulators from remote test leads.

Checks all types and sizes of buried insulators from remote test leads: Flanges, dressers, couplings, unions, carrier pipe to casing, whether parallel or in series.
 

100% accurate: Not affected by pipe-to-soil potentials or protection voltages.
 

Indicates continuity of connection between pipe and test lead.
 

Simple to operate: Simplified operation procedure reduces training time to 10 minutes, following step by step instructions.
 

Cost-effective: Saves time compared to present test procedures.

Built to provide years of dependable service, this precision instrument is light, compact, and housed in a rugged case, 4" W x 6" L x 3-1/4" D. This case provides adequate protection under all normal field conditions. Operates on 2 D Cells and 2 "AA" batteries.
