Part Number: 275597   
Price:  $2,325.00 
   Quantity:  
 
Manufacture: Yokogawa
Product Description: Model 2755 Measures resistances from the 100 m Ohms to the 110M Ohms Range by operation of switches. Batteries and the Galvanometer are self-contained, for your safety. The Front Panel is provided with power and galvanometer circuit selectors, One ratio arm dia, and four measuring arm dials.
Model 2755 is also equipped with a Murray and Varley Loop tester for convenient location of line faults such are "shorts" and "Grounds" in power, telephone, telegraph, and signal cables.
