Nakamura Simplified Ammeter, CA-50N

Overload prevention device protects meter against any current or voltage overload

* four distinctive colors used for different types of meters enable instant identification
* accuracy with JIS class 2.5 with high internal resistance
* long circular scale (84mm)provides easy and accurate reading
* multi-purpose terminals employed to prevent displacement of heads
* internal mechanism of instrument is completely visible
* lightweight, great impact strength, and no leakage
* flow of current is not interupted when device is connected or removed
* pointer indicates the direction of the flow of the current
* appropriate range (0.5A or 5A) selected by simply inverting the meter measuring ranges: 0.5A and 5A

SPECIFICATIONS

*By simply inserting the ammeter, current can be measured without disconnecting the circuit.
*Students can easily understand the mechanics because it is easy to see that the switch contacts are automatically closed when the ammeter is removed.
*The graduations are divided evenly on both sides and have no numerals.
*The center of the scale represents zero and each graduate registers 0.5A or 5A each.
