HABOTESTAC Voltage Detection: When the probe end of the voltage tester is close to the AC voltage source, the red signal indicator flashes; the stronger the signal, the faster the red light flashes; at the same time, the beeping sound of the buzzer will increase in frequency with the enhancement of the signal strength.
HABOTESTDigital differential pressure gauge, can capture the smaller pressure difference, reading intuitively and accurately, avoiding the inaccuracy caused by parallax and human reading error of pointer differential pressure gauge.
