From Transformer Turns Ratio Meters with the TR-SPY Mark III, Precision Micro Ohm Meters with the Micro Centurion II, to the Raytech line of Winding Resistance Meters that includes the WR14 and WR50-12.
Used in routine maintenance and acceptance testing and for investigating the core, windings, and tap changer settings of transformers for common problems.Raytech TR-SPY Mark III Three Phase TTR (Transformer Turns Ratio)
Designed for a high degree of accuracy for the measurement of very low resistance.
A battery or line-operated, field-portable instrument designed specifically to measure the dc resistance of all types of magnetic windings safely and accurately.
Offers the power to measure resistance of highest Inductivities in shortest time. Including the world unique demagnetizing function.
