Feature: 1. This frequency meter capable of measuring the frequency parameters of continuous carrier signal walkie‑talkies, with signal strength indicator. 2. It is the tool of choice for maintenance personnel, test frequency, and signal strength of wireless enthusiasts. 3. This portable frequency counter is designed to count continuous wave signal that comes from two‑way radio. 4. There are easy ranges for you to choose from. The ranges cover most of the two‑way radio frequency you want to measure. 5. Its four‑button control is easy to use and its small size allows you to carry it wherever you want. 6. Work by TCXO (X'tal temperature compensation (CRiSTAL) oscillator), in the range of ‑45℃ ‑ 65℃ can reach ± 2 ‑ ± 4ppm accuracy.
