Auditory Evoked Potential - At its best!
The ICS Chartr EP 200 builds on the expertise of our ICS Chartr line. Creating smaller, portable systems while maintaining the easy-to-use software interface valued by our customers. New features maintain the user friendliness and assist you in performing any AEP test with ease.
Comprehensive test battery
ICS Chartr EP 200 provides a comprehensive test battery for diagnosing a wide range of auditory and vestibular disorders. Users can create their own protocols or get an immediate start with the pre-loaded ones.

Easy navigation
The software interface ensures a smooth work process. Three easy access tabs make acquiring and reviewing data quick and intuitive. The New Test tab gives direct access to test protocols, the Quick Settings tab gives easy access to protocol parameters and the Review tab gives instant access to all saved data.

Improve patient care with VEMP
The ICS Chartr EP 200 comes with an optional VEMP module for a more comprehensive vestibular assessment. The VEMP module utilizes EMG monitoring with a unique device that eases the testing procedure and allows users to test with confidence.
Readily accessible VEMP protocols
A list of VEMP protocols are added under the New Test tab already known from the EP interface. Available protocols include: toneburst and click air conduction VEMP protocols, bone conduction VEMP protocol and OVEMP protocol. Users can also create their own.

Instant EMG monitoring
“The tonic state of the SCM muscle is a critical parameter in the recording method of the VEMP. Thus, controlling the level of tonic EMG would appear to be a prerequisite for the accurate interpretation of the VEMP”(1).
“The tonic state of the SCM muscle is a critical parameter in the recording method of the VEMP. Thus, controlling the level of tonic EMG would appear to be a prerequisite for the accurate interpretation of the VEMP”(1).
The ICS Chartr 200 VEMP monitor records the EMG level and thus makes VEMP testing a lot easier. The monitor assists in controlling the amount of tonic level EMG by making the patient and tester aware of the level through a series of lights. The monitor can be easily mounted or held by the patient during data collection.
Efficient Multi-frequency ASSR
The optional Auditory Steady State Response (ASSR) module is a great addition to the ICS Chartr EP 200, which allows you to obtain frequency specific, auditory data, quickly and efficiently.
RapidASSR™ algorithm
The RapidASSR™ response detection algorithm makes it possible to collect up 12 frequencies simultaneously (6 frequencies per ear). The proven algorithm uses a Fourier Linear Combiner with an adaptive filter and circular T2 statistical analysis*.

Instant monitoring of EEG and impedance values
The EEG is always viewable during data collection, making it easy to check the patient’s state. Impedance can be checked at any time during testing without interfering with data collection. Both timesaving features, ensuring that accurate data are collected.
