Pointer Frequency Meters
Pointer frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz. The accuracy class is 0.5. They are available in many different sizes: The ZQ 0407 with 48x48 mm front frame
The ZQ x307 group with a 72x72 mm front frame
The ZQ x207 group with a 96x96 mm front frame
The ZQ x107 group with a 144x144 mm front frame.
They can also use two different dials: the ZQ 0x07 with a 90 degree dial and the ZQ 2x07 with a 240 degree dial. Ship versions are available for ZQ 0307, ZQ 0207 and ZQ 0107 pointer frequency meters.
The ZQ 0107 pointer frequency meter has a 144x144 mm front frame and a 90 degree dial. It is the same as the ZQ 0107 (see photo), except it is larger.
The ZQ 0207 pointer frequency meter has a 96 x96 mm front frame and a 90 degree dial. It is designed for measurement of mains voltage frequency within five different measuring ranges (45-55 Hz, 48-52 Hz, 45-65 Hz, etc.)
The ZQ 0307 pointer frequency meter has a 72x72 mm front frame and a 90 degree dial. It is the same as the ZQ 0207 (see photo), except it is smaller.
The ZQ 0407 pointer frequency meter has a 48x48 mm front frame and a 90 degree dial. It is the same as the ZQ 0207 (see photo), except it is smaller.
The ZQ 0507 pointer frequency meter has a 45 x45 mm front frame and a 90 degree dial. It is designed for measurement of mains voltage frequency within five different measuring ranges (45-55 Hz, 48-52 Hz, 45-65 Hz, etc.)
The ZQ 2107 pointer frequency meter has a 144x144 mm front frame and a 240 degree dial. It is the same as the ZQ 2207 (see photo), except it is larger.
The ZQ 2207 pointer frequency meter has a 96x96 mm front frame and a 240 degree dial. It is designed for measurement of mains voltage frequency within five different measuring ranges (45-55 Hz, 48-52 Hz, 45-65 Hz, etc.)
The ZQ 2307 pointer frequency meter has a 72x72 mm front frame and a 240 degree dial. It is the same as the ZQ 2207 (see photo), except it is smaller.
