Product Details

The Armada Technologies Pro48K™ is the most widely recognized diagnostic tool in the irrigation industry. Often referred to simply as the "Pro48," this multi-function kit is designed to perform the three most critical electrical tests on a 24V irrigation system: verifying controller output, testing solenoid integrity, and "chattering" valves for easy location. By providing a portable 24V power source, the Pro48K allows technicians to operate valves even when the controller is inaccessible or dead. Its signature "Chatter" mode pulses the solenoid rapidly, creating a vibration and sound that can be heard through the soil, making it the go-to tool for finding buried valve boxes. Housed in a rugged, weather-resistant case, the Pro48K is the "Swiss Army Knife" for irrigation service professionals.

Key Features:

• Three Diagnostic Modes: Easily switch between testing the Controller (clock), the Solenoid (valve), or using the Chatter function to locate valves.
• Solenoid Activation: Provides enough current to open most standard 24V AC irrigation valves without needing a wall outlet or controller.
• Audible & Visual Continuity: Features a bright LED and a distinct beeper to confirm a complete electrical circuit or identify a broken wire.
• High-Voltage Protection: Built to withstand accidental contact with 120V AC, protecting the internal circuitry from common wiring mistakes.
• Heavy-Duty Leads: Comes with premium alligator clips and rugged, flexible wires designed for repetitive field use.
• Protective Carrying Case: The "K" in Pro48K signifies the complete kit, which includes a padded, zippered carrying case to keep your leads and unit organized.

Specifications:

• Compatibility: All standard 24V AC irrigation systems.
• Power Source: Two 9V Alkaline batteries (not included).
• Operating Voltage: 18V - 24V DC pulsed output (solenoid safe).
• Indicators: Red/Green LED for polarity and continuity; Internal beeper for chatter/continuity.
• Construction: High-impact ABS plastic with weather-resistant seals.
• Kit Includes: Pro48 Tester, leads, and the Pro21 padded carrying case.

Operation & Troubleshooting Tips:

• Finding a "Lost" Valve: Connect one clip to the station wire and one to the common wire at the controller. Switch to "Chatter." Use an Armada Pro-series locator or simply follow the sound in the grass to find the buried box.
• Testing the Controller: Switch the Pro48 to "Clock" mode and touch the leads to the controller terminals while the zone is active. The LED will turn Green if the controller is outputting the correct voltage.
• Verifying the Solenoid: Switch to "Solenoid" mode. If the LED turns Red, the solenoid coil is intact. No light indicates an "Open" (broken) coil that needs replacement.
• Battery Tip: If the "Chatter" sound becomes weak or the LED dims, replace both 9V batteries simultaneously for maximum performance.

Common Uses/Applications:

• Spring Start-Ups: Quickly verifying that every zone is firing before the controller is fully programmed.
• Valve Box Locating: Finding valves that have disappeared under years of mulch, dirt, or new sod.
• Wire Repair: Confirming that a newly made wire splice is providing a solid electrical connection.

Common Questions:

Q: Can the Pro48K damage my irrigation controller?

A: No. When used in "Clock" mode, it acts as a passive tester. However, it is always a best practice to disconnect the field wires from the controller terminals before using the "Solenoid" or "Chatter" power modes.

Q: Does it work on DC Latching (Battery-Operated) solenoids?

A: No. The Pro48K is designed specifically for standard 24V AC solenoids. It will not properly activate 9V DC latching solenoids.

Q: What is the difference between the Pro48 and the Pro48K?

A: The Pro48 is the standalone unit. The Pro48K includes the Pro21 padded zippered carrying case, which is highly recommended for protecting the leads in a service truck.
