Old, antiquated solenoid testers are no match for the brand new Pro50 from Armada. Let's face it, LED testers went out with the 90's. Digital is the best way to test, activate, chatter, and diagnose as digital processors can be programmed to deal with any situation. The digital capability of the Pro50 allows it to test AC, DC, high resistance, and any low voltage solenoid out there.
The Pro50 can do them all with the digital LCD screen, unlike the old analog models. But the digital multimeter built in really sets it apart. Different solenoids have different resistances and the meter diagnoses the actual voltages and resistance, letting the user decide what is good and what is not. For example, imagine an old solenoid tester, which are hard wired for a 20 to 60 ohm good range. Some DC solenoids read less than 20 ohms and will be diagnosed as shorts. On the Pro50, a 4 ohm solenoid reads as 4 ohms, thereby correctly identifying it as a good working solenoid. Digital is smarter.
In addition to digital features, the Pro50 also sends tracing tone for wire identification. The Pro50 uses 4 AA batteries for longer life. For long term affordability, the Pro50 features 24 inch detachable alligator leads (cords) so that if they deteriorate, they are easily replaceable. All for about $30 more than the old solenoid testers. Also a kit version, the Pro50K, comes with the Pro50, Pro210F Filter Probe, and zippered carry case is available.
