The TEQD-2301B is an analog, 0–400°C temperature controller designed for CBS series continuous band sealers, often interchangeable with the NGE-2301B model. It operates via a manual rotary knob for setpoint adjustment and is compatible with 110V or 220V AC input voltages. For technical, installation, and operation details, you can refer to the NGE-2301B Operation Manual . Analog Temperature Controller TEQD-2301B (0-400C-220V)
Since the model number suggests an industrial or electronic device (e.g., a controller, analyzer, or power supply), this content is written as a generic, professional-grade operations and maintenance manual suitable for field engineers, lab technicians, or maintenance staff.
