CED 2502SA skin conductance unit


The 2502SA stand-alone skin conductance unit is designed to take direct measurements of the conductivity between two skin electrodes by maintaining a 500mv DC potential across them, and then measuring the current needed to maintain this potential. This current value is then represented and output as a scaled voltage, suitable for connection to a CED 1401 laboratory interface.

The 2502SA uses the constant-voltage principle and has manually switched conductance ranges of 10, 25 and 100 micromhos. Suitable electrodes for Galvanic Skin Response (GSR) studies are supplied with the unit. The sockets accept 1.5 or 2 mm plugs.

The CED 2502SA is offered as research equipment and is not sold as a medical device within the meaning of the European Medical Device Directive.

Box size: 241mm x 241mm x 46mm (W x D x H), external mains-driven power supply.

Privacy policy

CED, through this site, does two things that relate to privacy. We would like to explain them.

Emails from down-loads

We offer free down-loads of many files on our site, from test programs to complete install files for updated versions of major packages like Spike2 and Signal.

When customers wish to take a down-load of a major package, we ask a few questions, including their name, email address, the serial number of the software for which they seek an upgrade and whether they would like an automatic email whenever we update the product. This information is emailed back to CED when they access the final down-load screen. Within this email, your browser transmits the type and version of browser you are using, and the screen resolution you are running.

The reasons why we take and keep this information are that it is useful for our software development team to know who has taken the latest versions, and it is useful for our web site development team to know which browsers people are using to view our site, and what resolution they have their screens set to.

Cookies

When people down-load a major package, we try to write a cookie, a small file in your computer, that records your name, serial number of the software package, and the version you are down-loading. These files have a lifetime of one year.

The reasons for storing this information are firstly that if you ask for another down-load some other time, your details are read from the cookie and are pre-written into the form, to save you looking them up again. The other reason is that next time you access our site, your browser looks through your CED cookies and compares the versions down-loaded with the latest version numbers read from our site. If there is a later version of a product you have already down-loaded, we tell you on the home page screen, so you know that it is worth going to the down-load page again.

None of this information is ever given to anyone outside CED. ×
