Instruments for electrical measurements

Description

These are precision instruments (cl. 0.5) designed and manufactured to be used in the laboratory for electrical engineering. The self-consumption and the response times of the meters are reduced to the minimum, and these are light and damped, resistant to shocks and vibration. The instruments are fitted inside containers made with impact resistant and shockproof material. The scales are traced with a high number of divisions: some instruments have more scales to avoid the use of multiplication factors. The moving iron instruments are shielded against external magnetic and hysteresis free fields and can be used in DC and CA, keeping within the precision class.

The following instruments are available:

- Ammeters


- Voltmeters


- Wattmeters

- Power factor meters


- Frequency-meters


- Galvanometers


- Ammetric transformers

- Shunts
