Description:

The Warner Instrument TC-344C is a versatile and reliable dual-channel temperature controller designed for precise temperature regulation in laboratory and research applications. This model provides temperature control from ambient to +65°C, and it features a dual-channel design with adjustable DC output for quiet operation, ideal for sensitive setups like electrophysiology.

In Auto mode, the unit maintains a set temperature automatically with a thermistor feedback loop, offering accuracy typically better than ±1°C and under ideal conditions as low as ±0.1°C. In Manual mode, the controller allows continuous DC output adjustable from 0 to 15 volts.

The TC-344C is equipped with multiple features, including independent temperature monitoring for each channel, external input for computer control, and an open-thermistor fault protection circuit to prevent overheating in case of thermistor failure. Its low-noise toroidal transformer power supply minimizes electrical interference, making it ideal for recording setups that require high precision.
