EEG/Sleep recorders that make no compromises on quality

Lifelines Trackit

Small, Compact, Reliable

With a reputation for consistently high performance, Trackit™ ambulatory recorders are used in some of the world’s leading hospitals and epilepsy centres.

Customers also rely on Trackit™ to produce lab quality recordings in the harshest electrical environment imaginable – the patient’s home!

Ambulatory and Sleep

Trackit™ was designed from the outset with both Ambulatory EEG and Sleep applications in mind.

Its small and compact footprint, when coupled with the paediatric backpack, makes it ideal for EEG recording applications in children and adults.

  • Features & Benefits

    Trackit™ can be worn unobtrusively for ambulatory EEG recordings, ensuring complete patient acceptance. Size does matter!


    Flexible recording inputs

    With 4 high level DC, 8 bipolar DC polygraphy, and 24 mono-polar EEG ensures that a wide range of monitoring requirements can be addressed. A built in or leaded connector block can be used depending on the…


    Data and recording flexibility

    Trackit’s unique architecture allows the system to be configured either as an ambulatory recorder with local storage, a headbox with cable or wireless communication to a host computer (Trackit™ Plus software). Trackit also allows a dual recording capability when doing host PC recordings – the EEG data will always be backed up on the Trackits internal flash memory


    Trackit™ Blue wireless EEG

    Monitor and acquire EEG on the Host PC using the unique Trackit™ Blue (Bluetooth class 1) internal wireless module. Automatically switches to Ambulatory mode when out of range. Dual PC and Trackit recording is also allowed.


    Robust and tamper proof

    The use of a strong metal box, a lockable battery bay and the use of plug-in batteries means that long recordings can be made with more confidence.


    A wide range of sampling rates

    Sampling rates from 1 – 512Hz with independent sampling on selected channels (Poly and AUX only) ensures application flexibility, especially when monitoring patients with sleep disorders.


    Signal integrity

    The use of a metal box and high quality amplifier components means that Trackit™ is perfectly at home in the harshest of recording environments.


    A safe recording medium

    The use of Compact Flash disks ensures complete data integrity for long recordings. Compact Flash disks are more reliable than hard disks; they consume less power, resulting in longer recording times. Compact Flash is a future proof technology – a safe investment.


    Removable battery compartment

    A removable battery compartment ensures fast and simple removal and replacement of batteries. Select from either disposable or rechargeable batteries.


    96-hour recordings

    Trackit™ has been designed at the outset as a 24-hour recorder with the maximum number of EEG channels selected at EEG sampling rates <256Hz. 96 hour recordings are possible using 3 Li batteries and a 4GB compact flash card (21ch).


    A completely open data format

    Trackit™ stores and transmits data in European Data Format (EDF). As a consequence, data generated by Trackit™ is compatible with any commercially available EDF file, including the most popular EEG and Sleep analysis software on the market today.


    Ease of operation and set-up

    Trackit™ has been designed at the outset with ease of operation and set-up in mind. A simple user interface with LCD display allows parameters such as time, battery and disk life to be monitored by the technician or patient. A Microsoft Windows set-up program allows recording parameters to be configured and loaded onto the device and recordings to be made while connected to the host computer.


    Easy annotation of patient events

    An event button is available for the patient to time stamp points of interest during the recording, allowing faster data reduction and review by the physician.



    A built in impedance check and calibration means that no extra hardware is needed when setting up the device. It is also possible to interrogate impedance values from the device during a recording.
