Posted By Rhys Ritchie Hello There, I wanted to purchase some equipment to do light and sound monitoring. I know that there are individual pieces of equipment that perform those functions. Could someone tell me where I can get good quality ones. However a colleague has told me that some of them come with software also and could be connected to a datalogger which would help with accuracy of the analysis of the results. Does anyone have any information on any of this. Any help would be appreciated as soon as possible. Thank you Rhys
