The multisensor probe can support 3 different sensors: DO, EC, pH or pH/ORP.

Features at-a-glance

Waterproof Protection - The HI769828 probe features an IP68 rating for continuous immersion in water.

Color Coded, Field Replaceable Sensors - Sensor replacement is quick and easy with field replaceable, screw type connectors that are color coded for easy sensor port identification.

Auto-sensor Recognition - The probe and meter automatically recognize the pH and pH/ORP probe sensors that are connected. Any ports not used on the probe will not have the parameter displayed or be configurable.

Automatic Temperature Compensation (ATC) - Integrated temperature sensor allows for automatic temperature compensation of pH, ion selective, conductivity, and dissolved oxygen measurements.

Available Sensors

The HI769828-0 is a PEI plastic body, double reference, gel filled pH electrode. This pH/ORP electrode for the Hanna family of multiparameter portable meters including the HI98280. The electrode has a rugged PEI (polyetherimide) body that offers excellent chemical resistance in an unbreakable plastic making it ideal for field and industrial applications.The HI769828-0 has a glass pH sensing tip with a double reference electrode in gel electrolyte and a cloth junction.

The HI769828-1 combination pH/ORP sensor features a glass sensitive bulb for pH readings, a platinum sensor for redox measurements and a double junction reference with gel electrolyte and cloth junction for use with the HI769828 probe.The electrode has a rugged PEI (polyetherimide) body that offers excellent chemical resistance in an unbreakable plastic making it ideal for field and industrial applications.

The HI769828-2 is a galvanic dissolved oxygen membrane sensor for use with the HI769828 probe. The sensor body is constructed of durable PVC material and contains an easily replaceable membrane cap design. The membranes are constructed of PTFE and each cap screws easily onto the sensor. The HI769828-2 sensor contains a silver cathode and zinc anode.

The HI769828-3 is a 4-ring electrode conductivity (EC/TDS/Resistivity/ Salinity) sensor for use with the HI769828 Probe. The sensor body is constructed of durable PVC material and contains AISI 316 stainless steel electrodes that are not subject to polarization or surface coating effects.
