3. Digital Multimeter NCV Auto-Ranging 6000 Counts TRMS Test Frequency Counter

The measurement must be made with correct input terminals and functions and within the allowable measuring range To prevent the meter from being damaged, the value to be input shall not exceed the extremes allowed by each measuring range.

When the meter has already been connected to the line being measured, the operator is prohibited from touching the input terminal that is not in service. When the voltage measured exceeds 60V DC or 30V AC (valid value),the operator shall be careful enough to avoid electric shock.

When the meter is used in the vicinity of the equipment that produces strong electromagnetic interferences, the reading on the meter will grow unstable and even produce serious errors. Don’t operate the meter whose appearance is damaged. The safety function of the meter will become null if the meter is not properly operated.

The meter must be operated with great care when working in the vicinity of an exposed conductor or bus line. The meter is prohibited from being used in the vicinity of any explosive gas, vapor or dust.

Highlighted Features:

  • Auto Shut-off, Anti Miss Plug make taking and recording measurements easier than ever before.
  • This digital multimeter is very suitable for diagnosing automotive, industrial and household electrical problems.
  •  NCV test and measure capacitance, diodes, live line and with selecting.
  • contact voltage detection function with a sensor to detect voltage and avoid electric shock without touching any wires. Light and sound alarm if detects the AC voltage(6-600V) or live line.
  • Power Reminder]Built-in explosion-proof ceramic fuse tubes, reverse Polarity protection, low battery indication, and overload protection for all ranges.

5. Digital Frequency Counter Bench Electronics Signal Meter

This frequency counter measures signals over a wide range from 0.01 Hz to 2.4 GHz. The gate time is continuously varying from 100ms to 10s. The maximum power consumption is only 5W. The instrument provides high performance stability and function at low cost. The counter can measure frequency, period and equal-precision. It is also featured with 3 step function selection, work state, unit and eight-digit LED display.

All functions in this frequency counter depend on a single CPU. A crystal-controlled temperature circuit provides a constant compensation for temperature change, thus reducing measurement errors typically caused by temperature drift. The Channel B (CH. B) input has an attenuator (x1, x20), AC/DC coupling for a low-pass filter.

Highlighted Features:

  • With 3 steps function selection: work state, unit & 8-digit LED display
  • Frequency measurement from 0.01 Hz to 2.4 GHz
  • Cyclic measuring range from 0.5 ms to 10 s
  • With attenuation of 20 dB and input impedance of 1 MO
  • With frequency, period and equal-precision measurement

8. Audio Frequency Counter

Frequency counter based on the microphone input. Counts when the input rises or falls past a set level and converts into into frequency or a time period. Results depend on your device and its hardware. If you just want to know the frequency of a sound with harmonics (e.g. mucial instrument), a FFT based app such as keuwlsofts spectrum analyser or guitar tuner will be better. This app can provide more accurate frequency measurement for single frequency input signals.

Features include: Displays triggered event count and frequency or time period. Graph of input signal, 2.5 ms/div up to 640 ms/div.
Gate time of 0.1s, 1s, 10s or 100s. Gain from x1 to x1000 Trigger on rise or fall AC or DC coupling Set a noise level so new event is not triggered until the signal has first passed this level.

Highlighted Features:

  • Open network sockets
  • Access information about networks
