Inkbird ITC-308S Dual Aquarium Heater for Freshwater & Saltwater

Description

Product Overview

The Inkbird ITC-308S is engineered to meet the demanding temperature regulation needs of both freshwater and marine aquarium environments. Built with a robust housing and a high‑precision sensor, the unit delivers accurate temperature readings to within ±0.5°C, allowing hobbyists to maintain optimal conditions for a wide variety of aquatic species. Its dual‑stage capability means you can attach both a heating element and a cooling device, such as a chiller or refrigeration unit, to the same controller, simplifying setup and reducing the need for multiple controllers.

Designed for universal compatibility, the ITC-308S operates on 100‑240 VAC input power, supporting 50‑60 Hz frequency and a maximum load of 1200 W. This flexibility ensures reliable performance whether you are using a standard 110 V outlet in North America or a 220 V supply elsewhere. The controller features a clear dual‑display window that shows both the current water temperature and the user‑set target temperature simultaneously, with the option to switch between Celsius and Fahrenheit units.

Durability is a core focus of the design. The unit’s internal circuitry is protected against corrosion, a common challenge in saltwater setups, thanks to a sealed enclosure and high‑quality components that resist the harsh marine environment. The compact dimensions—7.48 × 3.94 × 2.76 inches—and lightweight construction (1.76 lb) make it easy to mount on the back of a tank or place on a nearby shelf without taking up valuable space.

Beyond its core functionality, the ITC-308S includes a suite of safety features. High and low temperature alarms alert you instantly if the water temperature deviates beyond the set thresholds, while a sensor failure alarm notifies you of any issues with the temperature probe. These alerts can be configured to trigger audible beeps, ensuring you are aware of any problems even when you are not directly monitoring the aquarium.

Usage

Whether you are maintaining a small community tank for tropical fish or a larger reef aquarium housing delicate corals and ornamental shrimp, the ITC-308S adapts to a range of scenarios. For freshwater setups, the controller can be paired with a standard aquarium heater to keep temperatures stable during cooler nights, while the cooling function can be employed during summer heat spikes to prevent stress on fish. In marine environments, the dual‑stage capability is especially valuable, allowing simultaneous control of a heater and a chiller to maintain the narrow temperature band required by many coral species.

Installation is straightforward: connect the temperature sensor probe to the designated port, attach your heating and/or cooling devices to the appropriate output terminals, and set your desired temperature range using the intuitive dial. The controller’s universal voltage compatibility means you can use it in virtually any region without needing additional transformers. Once configured, the ITC-308S continuously monitors water temperature and automatically activates the heater or cooler as needed, providing hands‑free temperature management for weeks or months at a time.

For hobbyists who run multiple tanks, the ITC-308S can serve as a central hub for each aquarium, with each unit operating independently to meet the specific needs of its tank. Its clear display and audible alarms make it easy to keep track of temperature status across several setups, reducing the risk of overlooking a critical temperature shift that could harm sensitive species.

FAQ

Can the ITC-308S control a single device only?

Yes, the controller is flexible enough to operate a single heating or cooling device if you only need one function. You simply leave the unused output terminal unconnected, and the unit will manage the attached device according to the temperature setpoint.

What type of temperature sensor does the ITC-308S use?

The ITC-308S includes a waterproof, high‑accuracy thermistor probe designed for aquarium use. The probe can be submerged directly in the water, and its cable is insulated to prevent corrosion, ensuring reliable readings over long periods.

How do the alarm settings work?

Through the dial on the front panel, you can set high and low temperature thresholds. If the water temperature exceeds the high limit or drops below the low limit, the controller emits a loud beep. You can also enable a sensor‑failure alarm that sounds if the probe stops reporting data.

Is the controller compatible with LED lighting systems?

While the ITC-308S is primarily intended for heating and cooling devices, its universal voltage input means it can be powered from the same outlet as LED lighting systems. However, it does not directly control lighting; you would need a separate dimmer or controller for that purpose.

What warranty does Inkbird provide for this product?

Inkbird offers a one‑year limited warranty covering manufacturing defects. If any component fails under normal use within this period, you can contact Inkbird support for a replacement or repair, subject to warranty terms.
