Portable Frequency Counter with CTCCSS/DCS Tester

Surecom SF 401 Plus

Now works with Digital Radio DMR

Introduction:　
•The frequency meter is capable of measuring the frequency of the continuous carrier signal walkie-talkies , 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 way 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 -45 ℃ ~ 65 ℃ can reach ± 2 ~ ± 4ppm accuracy
