25-Watt Low-Frequency Transmitter
The Loc3-25Tx is a 25-watt low-frequency transmitter built for long-distance pipeline location, buried pipe and cable locating, and coating-defect mapping. Selectable ELF combinations down to 3 Hz suit longline work, alongside a 20 Hz to 9.82 kHz range.
The two-inch dot matrix display with LED backlight shows output current, volts, resistance and frequency, while direct-connection and clamp modes are selected automatically when an accessory is plugged in. Powered by a Li-ion rechargeable tray for the full 25 watts, and it delivers a constant current output with high-voltage protection.
Packaged in a rugged IP65 housing, the Loc3-25Tx protects against inadvertent connection to voltages up to 230 V AC and pairs with the vLoc3-DM and the wider vLoc3 receiver family.
