EDAN SE-1 Electrocardiograph

The EDAN SE-1 is a single-channel, portable resting electrocardiograph designed for routine 12-lead ECG acquisition and thermal recording in clinics, hospitals, and primary care settings. It pairs a foldable LCD screen (192 × 64 pixels) for real-time waveform preview with a built-in high-resolution thermal printer, allowing the clinician to preview the ECG signal before committing it to paper.

The device is built around complete digital filtering—including baseline drift suppression, AC interference rejection (50/60 Hz), and EMG filtering (35 Hz)—with automatic baseline adjustment to keep the trace readable during acquisition. Lead-off detection and alarm notify the user when an electrode loses contact, supporting acquisition quality. Operation can be set to auto or manual mode, and the rhythm lead is selectable from any of the 12 standard leads.

Power is supplied by a built-in rechargeable lithium-ion battery or AC mains (100–115 V / 220–240 V, 50/60 Hz). EDAN literature cites more than 3 hours of continuous operation on battery, with distributor documentation listing up to 6.5 hours depending on configuration and usage. The enclosure weighs approximately 2.3 kg with battery included and measures 300 × 260 × 75 mm, with a membrane keypad designed for wipe-down between patients.

The SE-1 carries CE marking under MDD 93/42/EEC as a Class IIa device (Rule 10) , certified by TÜV SÜD (CE 0123) , and is designed to IEC 60601-1 and IEC 60601-2-25 safety standards. It is Class I, Type CF, defibrillation-proof, and is not suitable for use in the presence of flammable anesthetics. The SE-1 is part of the same single-channel platform as the SE-100, and the two models share the core recording architecture and accessory ecosystem.

The SE-1 is built for facilities that need a straightforward, single-channel ECG device with preview display, integrated thermal printing, and battery-backed portability—without the footprint or cost of a multi-channel system.

Key Features & Benefits

Foldable LCD Screen for Pre-Recording Waveform Preview

The foldable 192 × 64-pixel LCD screen displays the ECG waveform in real time before recording begins, allowing the clinician to confirm signal quality, electrode contact, and baseline stability at the point of acquisition. The screen folds down when not in use, reducing the device footprint during transport and storage.

Built-In High-Resolution Thermal Printer

The integrated thermal printer produces single-channel ECG recordings on 50 mm × 30 m thermal paper at selectable paper speeds of 25 mm/s or 50 mm/s (±3%) . The printer is part of the main unit, so no separate printing device is required at the bedside or in the consultation room.

Complete Digital Filtering and Automatic Baseline Adjustment

The SE-1 applies digital filtering to address common acquisition artifacts: EMG filter at 35 Hz (−3 dB) , AC/DFT filter at 50/60 Hz (−20 dB) , and automatic baseline adjustment to counter drift during recording. These filters are designed to support trace readability without requiring manual re-adjustment between patients.

Lead-Off Detection and Alarm

The device includes lead-off detection and alarm, which alerts the user when a patient electrode is disconnected or making poor contact. This supports acquisition quality by drawing attention to cable or electrode issues before they affect the recording.

Auto/Manual Operation with Selectable Rhythm Lead

The SE-1 supports automatic and manual recording modes, allowing the user to choose between a pre-configured acquisition sequence and manual control over lead selection and timing. The rhythm lead is selectable from any of the 12 standard leads, supporting rhythm strips from the lead most appropriate to the clinical question.

Rechargeable Li-Ion Battery with AC/DC Power

The built-in rechargeable lithium-ion battery (14.8 V) supports operation away from mains power, with more than 3 hours of continuous operation cited in EDAN literature and up to 6.5 hours referenced in distributor documentation. The device can also run on AC mains (100–115 V / 220–240 V, 50/60 Hz), with automatic switching between power sources.

Compact and Portable with Membrane Keypad

At approximately 2.3 kg (with battery) and 300 × 260 × 75 mm, the SE-1 is designed for transport between examination rooms, clinics, and bedside locations. The waterproof membrane keypad supports routine wipe-down between patients, and the carry bag (optional) supports protected transport.

Safety Classification: Class I, Type CF, Defibrillation-Proof

The SE-1 is classified as Class I with internal power supply, Type CF (defibrillation-proof applied part) . The patient connection is fully isolated, and the device is defibrillation-proof, supporting use in settings where defibrillation may occur. It is not explosion-proof and is not suitable for use in the presence of flammable anesthetics.
