Description
Portable Laboratory Ammeter EP-2 (GOST 1845-52) in Carbolite Case
The Soviet portable laboratory analog ammeter of the EP-2 series is designed for accurate measurements of the RMS (root mean square) value of AC current at a frequency of 50 Hz in the range up to 2.5 Amperes. The electromagnetic measurement mechanism is housed in a rigid protective case made of impact-resistant carbolite (bakelite) with a secure metal latch and a leather strap for easy carrying. It is manufactured in accordance with the requirements of the Soviet standard GOST 1845-52.
Key Advantages and Features:
- Durable Carbolite Transformer Case: The top cover of the case flips open during measurement, and when closed, it securely protects the glass window and the pointer mechanism from impacts and dust during transport.
- Electromagnetic Measurement System: Features high reliability, resistance to short-term current overloads, and a long service life.
- Wide, Clear Scale: The high-contrast dial with a zero-adjuster on the front panel ensures accurate reading of measurements.
- Screw-Type Laboratory Terminals: Convenient threaded terminals at the top of the housing allow for secure attachment of test leads or probes.
- Collectible and Practical Value: The device is in demand both for equipping physics and electrical engineering laboratories and among collectors of vintage equipment or for loft-style interior design.
Compatibility and Applications:
- Laboratory and practical work in educational institutions, physics, and electrical engineering classrooms.
- Adjustment, verification, and testing of industrial and household AC electrical equipment.
- Equipping vintage measurement stands, interior decoration, photo studios, and film sets.

Expert Tip: Before starting measurements, place the ammeter on a flat horizontal surface and check the zero position of the pointer (adjust with the slotted screw of the zero-adjuster if necessary). The ammeter must be connected to the electrical circuit strictly IN SERIES with the load. To avoid damaging the measurement mechanism, do not exceed the maximum current of 2.5 A.
