Digital Frequency Counter is a precision instrument capable of measuring a wide band of frequency.

The instrument uses solid state, low drift circuitry to ensure a stable reading and a high accuracy. The instrument has eight digits LED display. Frequency Counter can measure frequency as low as 0.01Hz, while the highest measurable frequency is 2.4GHz.

The circuit uses a precision crystal controlled circuit to generate the time- base which ensures a high accuracy in measurement of frequency.

The frequency measurement is possible using time bases 100 msec - 10 sec. Frequency is indicated in KHz, MHz or GHz by LEDs.
