Frequency Counter

50 MHz Auto-Ranging
Frequency Counter Kit / Frequency Meter

I have substituted the (16x1) LCD that has a 2x7 header for a new LCD (16x1) that uses a straight 16 pad configuration (the 16x1 LCD with a 2x7 header is no longer available). The new LCD is easily used by spreading the ribbon cable and soldering it to the LCD (the pin holes are in order with the ribbon cable straight across so soldering is easy). The other end of the ribbon cable still connects to the PCB with a 2x7 header. The connection to the new LCD is easy and neat and makes a great project.   (See our disclaimer at the bottom of the page for kits sent outside the USA)

New!  HV input capacitors included for use on 120VAC lines. Instructions enclosed.

bullet

Reads frequency from 1Hz to 50MHz and displays it on a 16 character LCD display.

bullet

Auto-ranging with floating decimal point.

bullet

Up to 7 digits displayed

bullet

Auto-adjusting gate speed (0.1 sec to 1 sec).

bullet

Microcontroller-based circuitry provides for simplicity, ease of assembly, and  highly stable readout.

bullet

Sensitivity approximately 100 mV RMS (100 Hz to 2 MHz), 800 mV RMS @ 50 MHz.

bullet

Input overload protected.

bullet

Limited warranty.

New Design! With 2x7 Headers on the PCB for easy ribbon cable hook-up

Reads frequency from 1Hz to 50 MHz and displays it on a 16 character LCD display. Auto-range feature provides floating decimal point and automatic placement of suffix (Hz, KHz, or MHz). Gate speed automatically decreases to one second below 100KHz to display frequency with a resolution down to an amazing 1Hz. Must see to believe. Microprocessor-based circuitry provides for highly stable readout with no jitter. Soup up that home brewed function generator with a digital readout. Powered by a 9-volt battery (not included) or a 12VDC power pack (not included). Notice: I cannot guarantee the safe delivery of your kit to countries other than the USA as sometimes they are lost or stolen in route. To insure a kit overseas or send it UPS would cost much more than the cost of the kit. ( Kits ordered outside the USA are sent with no money back guarantee for lost or stolen merchandise). Thank You!
