Compact Digital non-contact laser tachometer RPM DT2234C+

The voltage / power / battery level indicator KA2284 contains five LED lights that light up progressively as the voltage increases, from green to red to yellow.
It is ideal for your projects that require voltage level indicators, such as battery capacity and audio level indicators.
The built-in potentiometer adjusts the range (sensitivity) of the LED display, and the DC or AC input can be selected via the P2 bridge.
The AC and DC input can be controlled with bridge P2: bypassed for DC, open for AC.
Adjustable power level through the potentiometer. Power Level KA2284 Indicator Module 5 LED features:
- Operating voltage: 3.5 - 12 VDC
- 5 level LED KA2284 controller
- Adjustable power
- 4 pin terminal:
       - IN: Input voltage to measure

The JDS6600 series DDS signal generator can generate sine waves, square waves, triangle waves, pulse waves and arbitrary waves, etc. The frequency will be up to 15MHz. And it has duty cycle correction, amplitude modulation function and frequency sweep function etc. It can display output signal, amplitude and frequency at the same time. This series has amplitude frequency characteristics, and the appearance is very delicate and beautiful. It can be applied in factories, schools, research institutes and laboratories. There are 5 models, JDS6600-60M, JDS6600-50M, JDS6600-40M, JDS6600-30M and JDS6600-15M. The main difference is the maximum sine wave output frequency. JDS6600 -15MHZ is the maximum output frequency of the sine wave.
