Hi, I need help on Koha. I want to use it to carry out an inventory of laboratory equipment such as oscilloscopes, tools, voltage sources.

There's nothing about Koha which limits you to cataloging anything in particular. It's really more a question about the ways you can express those objects in MARC. I would suggest looking for examples in other library catalogs (and not just Koha ones) to see how they handle things. Some examples from my library: Kill-a-Watt electricity usage monitor: https://search.myacpl.org/cgi-bin/koha/opac-detail.pl?biblionumber=253660 Infrared thermometer https://search.myacpl.org/cgi-bin/koha/opac-detail.pl?biblionumber=388857 LED pico pocket projector https://search.myacpl.org/cgi-bin/koha/opac-detail.pl?biblionumber=409595 Bicycle, 19 inch frame https://search.myacpl.org/cgi-bin/koha/opac-detail.pl?biblionumber=288738 Mobile hotspot https://search.myacpl.org/cgi-bin/koha/opac-detail.pl?biblionumber=592625 -- Owen -- Web Developer Athens County Public Libraries https://www.myacpl.org
