pH/Conductivity/Temperature Probe

The Conductivity Probe (DPC1-S) is a replacement combined multi-parameter electrode specifically designed for DLAB  Conductivity Probe (DPC1-S) pen-type multi-parameter meter and DPC1+ Bluetooth pen meter, integrating pH sensing (glass bulb), conductivity sensing (platinum electrodes), and temperature sensing (thermistor) into a single replaceable probe for comprehensive water quality analysis .

The  Conductivity Probe (DPC1-S) enables the DPC1 and DPC1+ meters to measure pH (-2.00 to 16.00 pH, accuracy ±0.01 pH), conductivity (0 to 19.99 mS/cm, auto-ranging, accuracy ±1.0 percent full scale), TDS (0.0 mg/L to 10.0 g/L with adjustable coefficient), salinity (0 to 10 ppt), resistivity (50 Ω·cm to 20 MΩ·cm), and temperature (0 to 60 degrees Celsius, accuracy ±0.2 degrees Celsius) .

The probe is pre-installed in new DPC1 and DPC1+ meter kits and is available as a replacement part to extend instrument service life—electrode replacement rather than complete meter replacement . The combined electrode design integrates multiple sensing elements into one probe, eliminating the need for separate electrodes for different parameters . The probe supports 1 to 3 point automatic pH calibration with buffer recognition and 1 point automatic conductivity calibration with standard solution recognition, and is compatible with CH, USA, and NIST standard buffer solutions for flexible calibration options . The probe shares the meter's IP67 dustproof and waterproof rating for reliable operation in harsh field environments .

For the clinical laboratory scientist, dialysis technician, and water quality specialist, the  Conductivity Probe (DPC1-S) ensures continued, accurate multi-parameter water quality monitoring of purified water systems, dialysis fluids, and pharmaceutical process water—critical parameters for ensuring patient safety during renal replacement therapy and drug manufacturing. The combination electrode design simplifies field testing by integrating all necessary sensors into a single probe, and replacement is straightforward for trained laboratory personnel.

For the patient, reliable replacement parts ensure continuous water quality monitoring in dialysis and pharmaceutical applications, preventing gaps in quality surveillance that could compromise patient safety.
