ILA-550 Inductive Loop Analyzer

 

Model ILA-550 Inductive Loop  Analyzer  .  Excellent tool for use with scanning type detectors

Features & Benefits

• Contains all the functions necessary to test newly installed loops and loop systems. A powerful troubleshooting tool. 
• Easy to use, fits in the palm of your hand. 
• Housed in an attractive, compact, impact resistant case. 
• Liquid crystal display (LCD) provides direct readout for ease of measurement. 
• Operates on internal batteries or from an AC adapter (included). The adapter also charges the batteries. 
• Battery level status shown on display. 
• Automatic shutoff if the selector switch is not moved within eleven minutes or if the battery voltage falls below a preset level - to conserve battery life. 
• Measures the leakage resistance of the loop to ground at 500 VDC. 
• Measures frequency and relative signal strength of a loop network connected to an active detector with a probe suspended over the loop (indirect method) or when connected to the loop terminals (direct method). 
• Measures loop inductance, resistance, and Q of a loop with NO detector connected. Unit provides excitation to measure newly installed loop at locations without power or a detector. 
• Measures the change of inductance (-DL) caused when a vehicle drives over the loop and remembers the greatest change encountered. Useful for properly setting detector sensitivity levels. 
• Comes with a nylon bag to carry the analyzer and all accessories.
