Specifications
- Plug-In Darkness Sensor for pump activation only when aquarium lights are off. No need for separate timer, or resetting timer after power outages.
- Float Switch Compatibility. A Float switch is available as an accessory, and is plugged into the control jack in the back of the pump. The float switch is connected to transistor-level voltage, providing safety and dependability.
- High Volume One Channel System. The Sentry is made to be used as a one-channel makeup water doser. Using the included long-life tubing set, the Sentry will pump up to 800mL per hour, or up to 5 gallons per day.
- Two-Channel Capability Built In, with digitally adjustable dosing rates from .3 ml. to 100 ml./hour per channel when used with the included 2-channel tubing set.
- A/C Control—Using the optional A/C controller, the Sentry can easily be controlled by other devices, such as pH controllers, electronic float switches or aquarium monitoring systems.
- Accuracy and Tubing Life Utilizing a heavy-duty, Swiss-made motor and precision gear drive system. The Sentry pumps at a constant rotor speed of 12 rpm when set at 300. For slower rates, the timing cycle is changed but the rotor speed remains constant. Since it doesn`t rely on friction to drive the pumping mechanism, the output of the pump will remain stable over very long periods of time. Also, since the rotor moves at such a slow speed, tubing life is significantly better than that of higher-speed, gearless pumping systems.
- Built-In Battery Backup—The built-in nickel cadmium battery pack will power the pump for over an hour, providing peace of mind during power outages or in moving the equipment. The settings not only stay in memory, but the pump will actually run on the battery for over an hour. When turned off, the memory of the last rate setting remains in the pump electronics for 24 hours, so when turned back on, it rapidly returns to the previous setting.
- Precision Gear Drive—Internally the Swiss-made motor and gearbox power the rotor at 12 RPM, providing 24/7 operational capability as well as consistent dosing rates. To see the gear drive assembly, which is normally hidden within the pump.
- Bright LED Display—Easily visible from a distance or underneath darkened cabinets. Quiet Operation. This pump runs exceptionally quietly, making less noise than most desktop computers.
- Fixed-Dose Capability—Easily set a fixed volume to be dosed using the "dose" control button, providing a simple way to administer medications or other one-time additions of materials, or to acclimate livestock by adding a fixed volume of aquarium water.
