  I think there are two basic approaches that can be taken to connecting the
instruments to a PC:

1.  Digital
  Locate instruments that provide a serial or parallel port for connection.
See

http://www.alphalink.com.au/~derekw/ane/anemain.htm

for an example.

2.  Analog
  The electrical signal from the instruments must go through some sort of A2D
(Analog-to-Digital) conversion.  Boards to do this can be fairly expensive,
but an old analog joystick port may be usable and can be found cheaply.

  On the web server, a CGI script, ASP page or other "dynamic" HTML construct
allows current values to be retrieved and presented in the context of a
template page.
