Hanna HI1285-61 pH/EC/TDS Multiparameter Probe with CAL Check

Hanna HI1285-61 Multiparameter Probe is a highly versatile 3-in-1 pre-amplified sensor engineered for simultaneous measurement of pH, electrical conductivity (EC/TDS), and temperature within a single, compact probe. Designed specifically for use with the HI9813-6 portable multiparameter meter, this probe enables seamless utilization of the CAL Check™ feature, ensuring enhanced calibration confidence and consistent measurement accuracy in both field and laboratory environments.

Constructed with a rugged polypropylene body, the HI1285-61 offers excellent resistance to chemical exposure and mechanical stress, making it suitable for demanding industrial, environmental, and agricultural applications. Its integrated design reduces the need for multiple sensors, simplifying workflows and improving efficiency during routine water quality testing.

The pH measurement component incorporates a cloth junction and maintenance-free polymer gel electrolyte, minimizing maintenance requirements while ensuring stable and reliable readings. The low temperature glass sensing bulb enhances performance in low conductivity samples, making it particularly suitable for natural water sources, irrigation systems, and environmental monitoring.

For EC and TDS measurements, the probe utilizes two stainless steel pins that provide accurate amperometric determination of conductivity and dissolved solids. This robust design ensures long-term durability and consistent performance, even in challenging sample conditions.

A built-in temperature sensor delivers automatic temperature compensation for both pH and EC/TDS parameters, ensuring precise and repeatable results regardless of temperature fluctuations. This feature is critical for maintaining measurement integrity across different sampling environments and conditions.

The HI1285-61 is widely used in water treatment, agriculture, aquaculture, environmental monitoring, and industrial process control, offering a reliable all-in-one solution for comprehensive water analysis. Its compatibility with CAL Check™ functionality further supports quality assurance and accurate calibration verification.
