Product introduction
The frequency meter capable of measuring the parameters of the frequency of the continuous carrier signal walkie- talkie
,with signal strength indicator. it is the tool of choice for maintenance personnel, test frequency and signal strength of
wireless enthusiasts. This portable frequency counter is designed for counting continuous wave signal comes from Two-
way Radio. There are easy ranges for you to choose. The ranges cover most of the frequency of the two-ways-radios you
want to measure. Its four-button control is easy to use and its small size allows you to carry it anywhere you like.Work by
TCXO(Temperature Compensate X'tal (crystal) Oscillator) ,In the range of -25
℃
~ 55
℃
.
