The IDS 4320W is a precision digital sensor tailored for ultra-pure water and high-resistivity measurement, delivering exceptional low-conductivity performance in controlled laboratory environments with the MultiLab platform for benchtop analysis. With embedded IDS intelligence and compatibility with the YSI Water Monitoring Panel, it supports continuous online process verification.
Its low cell-constant stainless-steel design minimizes contamination risk, making it ideal for pharmaceutical, semiconductor, and ultrapure water production.
- Plug-and-play Simplicity: IDS sensors store calibration data and automatically transfer it between instruments, saving setup time and reducing errors.
- Precision stainless-steel, two-electrode design built for purity: With a stainless-steel body and a low cell constant (K = 0.100 cm⁻¹), the 4320W maintains measurement fidelity in ultra-pure and high-resistivity applications.
- Flexible Integration: Fully compatible with the YSI MultiLab platform (wired and wireless) and the YSI Water Monitoring Panel for seamless lab and field use.
Calibration
Engineered specifically for ultra-pure water applications, it comes factory-calibrated and is intentionally non-user-calibratable to maintain the highest measurement integrity.
Wireless Functionality
Wireless MultiLab probes require a WA-S wireless sensor module (not included). Each wireless sensor must have a WA-S module installed, and each MultiLab meter must be equipped with a WA-M wireless meter module.
For convenience, we recommend the MultiLab WA Kit, which includes:
- One WA-S wireless sensor module
- One WA-M wireless meter module
- One WA-S module charger
- One USB power supply for the charger
Wireless sensors are compatible with the MultiLab 4010-1W, 4010-2W, and 4010-3W models. They may also be used with the MultiLab 4010-1 if the latest firmware is installed (see firmware page).
Platform Compatibility
- MultiLab Platform: Fully compatible with YSI MultiLab benchtop meters, offering both wired and wireless measurement options for reliable laboratory or field operation.
- YSI Water Monitoring Panel (WMP): Provides plug-and-play connectivity for continuous water quality monitoring. Calibration data transfers automatically for simplified maintenance and reduced downtime.
