Description

Expanding the LR-20 series of backpack electrofishers, the LR-20B Electrofisher combines 400 watts of output power with the simplicity of our classic Model 12 Electrofisher, while using the standard accessories of the LR-24 Electrofisher. The LR-20B offers the same rugged features and easy-to-use controls of the original LR-20, with increased output power.

Features

Easy to Use Interface

Simplified control knobs and streamlined settings allow adjustment over output frequency and duty cycle. All controls are housed inside of a non-conductive, waterproof enclosure with a shatter resistant hinged and latched cover. The easily accessible external anode, cathode, control plugs and battery connector make the connection of electrodes and battery pack quick and simple.

Output Controls

The rotary Output Frequency switch controls the frequency (pulses per second) of the LR-20B in 5 and 10 hertz increments. The Duty Cycle switch controls the percentage of time the output pulse is on. It also allows switching to straight direct current (DC) or gated bursts of either 2 or 3 pulses. The timer reset button resets the number of seconds the output of the LR-20B has been active.

LCD Display

The easy-to-read backlit LCD display shows real-time status of output voltage, output current, waveform settings, output time, remaining battery life, and internal temperature.

Safety Features

Many built in features assure that the LR-20B is safe for both operator and collectors. The audio alarm provides a loud audio warning whenever 30 volts or more are present between the anode and cathode. A bright red warning light also flashes once per second while output is active. The emergency shutdown switch turns the unit on when the switch is in the up position but allows the unit to be readily shut down by flipping the red cover down in the event of an emergency. The front cover - which is secured by two over-center toggle latches - must be closed for the output of the LR-20B to be activated. An immersion sensor automatically turns the output off if water should come in contact with the LR-20B case and a tilt sensor shuts off output if the LR-20B is tilted over too far.

Packframe and Suspension Harness

The packframe and suspension harness allow for adjustment of the shoulder straps and waist belt to fit most people comfortably. The straps and belt all have quick release latches that allow the LR-20B to be removed quickly if the operator falls into deep water or becomes injured.

Cross-unit Compatibility

The LR-20B shares the same connectors as the LR-20 and LR-24 electrofishers, making all electrodes, battery packs and related accessories interchangeable between units. This maximizes your equipment flexibility in large field operations and increases the versatility of your inventory of electrofishers.
