Product Q&A

Q:Why is real-time conductivity monitoring essential in data center liquid cooling?

In liquid-cooled IT systems, ion build-up from fluid degradation or pipeline leaching elevates coolant conductivity, increasing short-circuit and electrochemical corrosion risks. Continuous inline monitoring provides early warning for coolant replacement and DI resin cartridge exhaustion.

Q:How to choose between cell constant K=0.1 and K=1.0 for cooling systems?

Select K=0.1 for high-purity deionized water in secondary cooling loops with measurement range from 0.1 to 200 uS/cm. Select K=1.0 for glycol-water solutions or primary cooling loops with measurement range from 1 to 2000 uS/cm.

Q:Does the transmitter support integration with DCIM systems or CDU PLC controllers?

Yes. The TDS210-B controller is equipped with standard RS485 Modbus-RTU and isolated 4-20mA outputs, enabling direct data acquisition by DCIM, BMS, or local CDU PLC platforms. It also includes 2 SPDT relays for automated high/low alarms.

Q:What are the wetted material and pressure limits of the TDS7001G sensor probe?

The probe is machined from 316L stainless steel with PTFE/EPDM seals and rated IP68. It withstands working pressures up to 5 bar for standard models and up to 7 bar for K=1.0 models, fully satisfying typical CDU operating pressures.
