印度采购需求：波浪传感器、波浪浮标、潮汐记录器、绞盘、营养物分析仪、凯夫拉绳

We previously purchased two units of a disposable buoy designed for monitoring ocean surface conditions, including temperature, salinity, and GPS location. We found the buoys to be quite effective for our needs in data collection. Could you please provide the datasheet for this product? It would greatly assist us in understanding the specifications and features, as well as any maintenance or operational guidelines. Thank you!
