GODIAGSHOP.COM has released three Godiag PIRT Power Probe multi-use circuit-testers with built-in diagnostic power. Godiag GT101 covers all functions of the others, GT102 supports the same function as GT101 but it cannot display current. GT103 is the most cost-effective while it doesn’t support AC voltage, Current display.
Check the comparison table carefully.

Function:
- GODIAG GT101/ GT102:
PIRT Power Probe + Car Power Line Fault Finding + Fuel Injector Cleaning and Testing + Relay Testing Car Diagnostic Tool
The same functions:
DC voltage, positive and negative voltage output, component activation, voltage display, Open circuit detection, Short circuit detection, Fuel injector test/cleaning, Relay test and Flashlight.
The different function:
GT101 supports current display while GT102 does not.
- GODIAG GT103:
Mini Pirt Electric Circuit Tester+ Car Power Line Fault Finding+ Fuel Injector Cleaning and Testing+ Relay Testing Car Diagnostic Tool
It supports DC voltage, positive and negative voltage output, component activation, Open circuit detection, Short circuit detection, Fuel injector test/cleaning, Relay test and Flashlight.
All three Godiag PIRT Power Probe testers don’t support AC voltage, Resistance and Oscilloscope function.
Therefore, how to choose the best one?
If you need to do Current function, you’d better choose GODIAG GT101 4 IN 1 PIRT Power Probe. If you need to display Voltage, GODIAG GT101 and GT102 both are OK.
If you want to choose the cheapest PIRT Power Probe with high quality, Godiag GT103 is the best choice.

- Detect Car Circuit Easily
The traditional multimeter doesn’t support live line measurement, which may burn out the multimeter. Test lead generally allows only 1.5 meters for 2-hands testing. Outage measurement may damage the car. You’ll have to know where the GND is if judging by voltage… Godiag GT103 can help to avoid all these trouble.
| Test Work | Multimeter | GT103 Electric Circuit Tester |
| Live working | Nonsupport | Support |
| Positive & negative output | Nonsupport | Support |
| Distance | 1.5 meters test lead | At least 6 meters |
| Protection | Fuse(need to replace if burn out) | 10A protection(automatically recover after power failed) |
| VCC | Support(need experience) | Support(red light flashes) |
| GND | Support(need experience) | Support(green light flashes) |
| Operation | 2-hands | Single hand |
