Multi-Function Frequency Counter Detector PPM with Measurement Range 1Hz～100MHz

Overview:

  The multi-function counter is developed by using the microprocessor technology. It is a precise test instrument. The biggest feature of this instrument is the use of reciprocal counting technology, high measurement accuracy, wide frequency measurement range, high sensitivity and fast measurement speed. With PPM measurement function, the preset frequency F0 can be set arbitrarily. This instrument is suitable for post and telecommunications, electronic laboratories, production lines, teaching and scientific research.

Features:

■ Single-chip control

■ Equal precision measurement

■ Measurement speed 20 times/second

■ Cost-effective, high reliability

■ F0 can be set arbitrarily during PPM measurement

■ PPM FM meter for crystal industry

■ A channel has low-pass filter and 20 times attenuation

■ 10-bit LED display (8 data bits, 2 index values)

■ New conductive rubber light touch button, beautiful appearance
