Fast, accurate wire and valve locating...the choice of irrigation professionals

Description:

The new and improved 521A Wire and Valve Locator builds on the success of the industry-standard Model 521. The new 521A has added features such as: loudspeaker listening, an extended locating wand for comfort, a slimmer case and a change to easy-to-find “D” cell transmitter batteries. Like its predecessor, the 521A combines adjustable transmitter power with a sensitive locating receiver to allow location of buried wires and valves with speed and confidence.

Features:

• High power transmitter offers extended long range and allows use on higher resistance wire paths.
• Adjustable transmit power allows you to select the best signal for maximum performance.
• Receiver provides adjustable loudspeaker audio, headset audio and visual indications of signal strength.
• Long-nose receiver wand makes it easy for you to move along quickly to locate even the longest wire path.
• Valve solenoid ‘hotspot’ signal makes pinpointing valves easy.
• Rugged headphones block ambient noise.
• Includes transmitter, receiver, headset, ground stake, and slim-line carry case.
• Battery-operated (eight “D” cell batteries and one 9V included).
• 1-year warranty.

Description:

Tempo continues its excellence in irrigation system troubleshooting with the introduction of the new Model 24B Station Master Pro. The upgraded Station Master Pro is a portable, battery-operated irrigation system diagnostic tester combining solenoid activation and wire identification. The easy-to-understand LEDs notify the technician if sufficient voltage is being supplied by the controller and the condition of the solenoid. The solenoid activation mode is used to activate valve solenoids either from the controller or at the valve, along with testing continuity of the solenoids. In chatter mode the Station Master Pro will turn the solenoid off and on about once per second to aid in locating the valve by ear. In addition, the Station Master has the added functionality of providing tone generation to identify wires which can be traced with any Tempo 200 Series tone probe. The Model 24B operates on two 9 volt alkaline batteries and can safely hold open a working solenoid for hours. The test leads come equipped with premium "bed-of-nails" and piercing pin bent nose clips for use on insulated wires, allowing the technician to connect the unit without cutting or stripping the wires. The unit is housed in a high impact ABS plastic case designed to withstand the rigors of daily use in the field.

Features:

• Troubleshoot irrigation systems.
• Chatter mode for audible locating of valves.
• Activate any 24V AC valve solenoid.
• Test solenoids for continuity.
• Send tone to identify wires.
• Check clock AC voltage.
• Low battery indication.
• Easy-to-understand LEDs.
• Test leads with "bed-of-nails" and piercing pin plips.
• Tracing valve wiring.
