The experiment set TESS Electrophysiology

Seven introductory experiments for heart,

eye and muscle.

What happens when our heat beats, whether dur-

ing rest or during and immediately after physical

exertion, when our eyes move, e.g. while reading a

text, or when we strain and stretch our muscles?

We can study these activities using non-invasive

electrophysiological methods. TESS Electrophysiogy

includes the complete equipment to perform seven

exciting experiments.

Features7 exciting health-related experiments

Set includes all components to perform the experiments and analyse the results

Wireless data transmission for experiments in sports medicine

Easy to use (plug & measure), perfect for first-time computer use in sciences

Literature with student work-sheets and teacher answer sheets

Long-term measurements possible, e.g. for fitness tests

product information

The following experiments are documented in the manual with student worksheets and com-plementary teacher answer sheets:

We investigate our heart beat (electrocardiography, P1332760)

We determine our heart frequency (P1522060)

We investigate our physical fitness (the heart under stress, P1522160)

We investigate our muscular power (electromyography, P1350360)

We measure our eye movements (electrooculography, P1350460)

We measure our reading speed (measuring reading skills, P1522260)

Electronystagmography (P0873560)

TESS Electrophysiology

TESS set with the wireless measurement system Cobra4 for one student workgroup,

can also be used for demonstration.

Scope of delivery:Wireless transmitter and receiver units to connect to the electrophysiology sensor and to a PC, can also be used for others sensors to measure parameters common in physics, chemistry, biology and medical educationelectrophysiology sensor unit for ECG, EMG and EOG with connectors for three measurement leads3 separate and shielded leads, color-coded (red, yellow, green) with 3.5 mm phone jacks to connect to the sensor unit and 2 mm jacks to connect to reusable and disposable electrodes3 reusable stainless steel ECG electrodes, contact area 30 x 80 mm with connectors for leads3 reusable EMG electrodes with cable and 2 mm connectorsdisposable electrodes (100/pkg)3 crocodile clips for disposable electrodeselectrode cream to improve contact between electrodes and skinsoftware for wireless and wired data acquisition, for data analysis, automatic sensor recognition, automatic setup of measurement parameters and integrated experiment instructions68-page manual with experimental literaturestorage box for instrument set and accessories

The TESS set takes advantage of the easy to use meas-

urement technology of Cobra4 with its plug & measure

concept and wireless data transmission, thereby help-

ing students to perform the experiments without hav-

ing to master complex equipment first. Just attach the

measurement electrodes to the skin surface, switch on

the instrument and start measurement. No need for

changing hardware or software settings. What is more,

the versatile experiments documented in the manual

introduce popular health and sports-related topics.
