Supmea SUP-TDS7002 4-Pole Conductivity / TDS Sensor with PT1000

The Supmea SUP-TDS7002 is a versatile industrial conductivity sensor utilizing advanced 4-pole technology. Unlike standard 2-pole sensors that are limited to specific low or high ranges, this unit offers an exceptional dynamic range, capable of measuring everything from relatively clean water to highly concentrated acids and bases with a single probe.

Equipped with an integrated PT1000 temperature element, the sensor ensures precise automatic temperature compensation across fluctuating process conditions. Its robust PBT construction and 4-pole design make it highly resistant to polarization effects and fouling, ensuring stable readings even in dirty or harsh wastewater environments.

Key Features & Benefits

• Wide Dynamic Range: Capable of measuring from 10 µS/cm up to 500 mS/cm. This versatility simplifies inventory, as one sensor model can cover cooling towers, wastewater, salinity, and chemical concentration applications.

• Advanced 4-Pole Technology: By separating the current-driving electrodes from the voltage-sensing electrodes, this sensor virtually eliminates polarization errors and compensates for cable resistance. It is also significantly more tolerant of electrode coating (fouling) than traditional 2-pole designs.

• Integrated Temperature Compensation: Built-in PT1000 RTD provides fast response to temperature changes, allowing your transmitter to calculate accurate conductivity and TDS values regardless of thermal shifts.

• Robust Industrial Build: The body is constructed from durable PBT (Polybutylene Terephthalate), offering excellent chemical resistance and mechanical strength.

• Standard Process Connection: Features a 3/4" NPT Male thread, making it easy to install in standard pipe tees, tank adaptors, or flow cells.
