FAQs
How do I select between electrode constant K=0.1 and K=1.0?
Choose K=0.1 for low-conductivity and ultra-pure water applications (range: 0.1-200uS/cm). Choose K=1.0 for standard industrial coolants, liquid cooling loops, and general water treatment (range: 1-2000 uS/cm).
Is this meter suitable for data center liquid cooling systems?
Yes. The 316L stainless steel probe (IP68 rated) withstands operating pressures up to 5-7 bar and temperatures up to 100°C, providing continuous online monitoring to prevent coolant degradation and protect cooling loops.
What output signals and protocols does the controller support?
It features standard isolated 4-20mA and RS485 Modbus-RTU for PLC/DCS integration, along with 2-way SPDT relays for high/low threshold alarms and automatic dosing control (optional 4G wireless available).
Can we customize the sensor cable length and thread connections?
Yes. While standard cables are 5m and threads are G3/4" or NPT3/4", we support custom cable lengths (10m, 15m, 20m, 30m) and process fittings for pipeline insertion or immersion installations.
