What is the security code for my Hardy Instrument?

If you have a HI 2110WI or a HI 2151/30WC, your security code (SEC CD) is 5321.

The security code for your HI 3010, HI 3030, HI 4050 or HI 4060 (and the older HI 2160RC, HI3300, and HI 3600) is set by the customer. If you forgot your security code please call Hardy Tech Support at 858-278-2900 Option #4 or 800-821-5831 Option #4, or email hardysupport@hardysolutions.com.

On the 6000 series units, if you forgot your security code, you would be required to get online with the unit through the web-server and check the security page for your codes.  The factory cannot help you with forgotten codes on the 6000 series units.
