Frequency meters

APPLICATION
CA37, CA39 and CA32 pointer frequency meters are moving-coil meters with built-in measuring transducers intended for measuring voltage frequency in AC electrical networks.
These meters can be mounted on panels of any kind of materials.
We deliver together the meters:
- two screw holders to fix the meter on the panel,
- a terminal shroud (on request),
- a service manual.
BASIC REQUIREMENTS, USER`S SAFETY
CA series meters are destined to be installed on panels or switchboards.
They are in conformity with EN 61010-1 standard requirements.
