菲律宾采购需求：电导率分析仪，电导率控制器，电导率仪，电感式电导率仪，实验室电导率仪，在线电导率仪

I'm interested in sourcing two types of Total Dissolved Solids (TDS) meters: inline and portable, both with digital displays. For the inline model, I'm looking for options that can provide continuous real-time monitoring, suitable for various applications. For the portable version, I need a user-friendly device that allows easy mobility and quick readings. Please include details on specifications, available features, pricing, and lead times for each type. Any recommendations based on reliability and performance would also be appreciated. Thank you!
