6. bayite DC 5-120V 100A Mini Digital Current Voltage Amp Meter Ammeter Gauge with Hall Effect Sensor Transformer
Feature
Through-hole design: No wiring difficulty. Measure positive or negative current. No current direction limitationElectrically isolated from high voltage power source which eliminates risk to delicate monitoring equipment and also minimizes safety concerns
Display Voltage or (+ -)Current. Voltage Range: 5V-120V. Current range: 0-100A
Large wire capability: Diameter of the hole through sensor is 3/4 inch(19 mm)
Loop through sensor multiple times to strengthen signal. For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps
Description
bayite Hall effect current meter reads current by detecting the magnetic field around the wire, there is no electrical contact which eliminate risk to delicate monitoring equipment and also minimizes safety concerns. The sensor doesn't get hot like the current shunt sense resistor which can have thermal temperature heat dissipation issues.Three display modes:
1, alternately display Amps and Voltage
2, only display Amps
3, only display Voltage
Specifications:
Measurement Range: + -100A
Accuracy: + - 1%
Resolution: 0.3A
Working current: 7-15mA
Power supply: DC 5-120V
Product Dimensions: 48mm*29mm*23mm
Mounting hole: 45.5mm*25.5mm
Sensor hole diameter: 19mm
Operating temperature: -4F - 140F (-20C - 60C)
As the resolution is 0.3A, the current reading might be flickering with 0.3A difference. For example, if the current is 1.7A, you might see a 1.7A and 2.0A alternatively. This is normal.
If your signal is too weak or you are not getting the resolution you want, you can coil the wire through the current sensor as many times as you want to double, triple, or quadruple the sensitivity or resolution.
For example, if your current signal is only 0.2 Amps, you could loop the wire through the sensor 10 times and the signal would by 10X stronger and would appear as 2.0 Amps.

Empowers You to Save Hundreds on Electric Bills
Electricity bills are rising. Now you can cut down on costs and find out what appliances are actually worth keeping plugged in. Simply connect these appliances to the Kill A Watt, and it will assess how efficient they really are. The large LCD display counts consumption by the kilowatt-hour, the same as your local utility. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring voltage, line frequency, and power factor. Now you will know if it is time for a new refrigerator or if that old air conditioner is still saving you money. Kill A Watt can help you reduce your power bill and will help find power-wasting appliances so you are able to decide whether it is worth keeping them plugged in. For standard 115 VAC appliances only, 15 amps maximum, 125 VAC maximum.Find Out How Much Electricity You're Using
 Large LCD display counts consumption by the kilowatt-hour |
Test The Quality of Your Home's Power
But measuring appliance consumption is just the tip of the iceberg. Because it can monitor voltage (Volt) and line frequency it can also test if an outlet is working, or evaluate the quality of the electrical power provided by your utility company. It can detect voltage drops around the house, help to predict brownout conditions or to make sure a new home's outlets are in working condition before escrow closes.
 The LCD shows all meter readings: volts, current, watts, frequency, power factor, and VA |
