Fish Guardian Pro
FGP5000
$575.00
The Fish Guardian Pro FGP5000 is an underwater snail barrier and a device that can be used to anesthetize fish in the lab or the field. In the barrier mode it will prevent evasive New Zealand mud snails from working their way into fish hatcheries and other locations where fish would digest these snails. When the battery voltage is greater than 20 volts (typically two 12-volt sealed lead acid batteries in series) the controller switches to fish / anesthesia mode. A small tub of water about 2 feet wide and about 8 inches deep with electrodes on two sides of the tub can be used to anesthetize fish. After 10 to 15 seconds the fish will be immobilized and can be placed in an adjacent tub of water where the fish can be processed before regaining consciousness in about a 3 to 5 minutes. The controller is powered from a battery not an AC power supply. The controller has several features:
· Probe Measurement Data (Voltage, Current, Resistance)
· Battery Voltage Measurement
· Automatic Switch to Fish / Anesthesia Mode when Battery Voltage > 20 Volts
· Automatic Probe Polarity Switching after 24 hours (Barrier Mode) and 71 minutes (Fish / Anesthesia Mode)
· Pulse Countdown to Polarity Switch
· Barrier Effectiveness Parameter. Shows Maximum Supported Probe Length (Barrier Mode Only)
· Display Probe Polarity Indication
· Warning / Error Messages (Low Probe Current, Low Battery Voltage, Over Current)
· Probe Short Protection
· Plug and Play Operation, no Configuration Needed
· Case comes with Two Mounting Holes (4.755” apart)
· Includes 6” Power and Probe Pigtails
