HI-98194 Multiparameter Waterproof Meter information

Hanna's extended description

HI-98194 provides multi-parameter measurement in a compact and rugged IP67 waterproof enclosure. Ideal for demanding application, this meter features our rugged, quick connect multi-function probe with field replaceable sensors.

A backlit, graphic LCD provides easy to read resolution even in low-lit areas. A combination of dedicated and soft keys allows easy, intuitive operation in a choice of languages.

HI-98194 allows users to store up to 45,000 continuous or log-on demand samples with logging intervals from one second to three hours. Logged data can be later transferred to a PC with the HI-920015 micro USB cable and Hanna software.

Comprehensive GLP data includes data from the last five calibrations. The contextual Help Menu can be accessed to obtain on-screen information and assistance about each feature at the touch of a button.

The HI-7698194 probe features a quick connect DIN connector to make attaching and removing the probe simple and easy.

Probe Details

The HI-7698194 is a multiparameter pH/EC/DO/Temperature probe for use with the HI-98194 portable meter.

It features a quick connect that makes a waterproof connection with the meter. Sensors are automatically recognised by the probe and meter when connected.

Any ports not used on the probe will not have the parameter displayed on the meter. Sensor replacement is quick and easy with field replaceable, screw type connectors that are colour coded for easy sensor identification.

The probe features a multistrand-multiconductor shielded cable with 4m, 10m, 20m, and 40m lengths available. It’s rugged, waterproof design makes it ideal for field use. IP68 sensor.

Rugged Carrying Case

The HI-98194 meter, probe, and all accessories are supplied in a rugged carrying case designed to provide years of use. The inside compartment of the carrying case is thermoformed to securely hold and protect all of the components.

Din Connection


Electrode is dust-tight and protected against the effects of continuous immersion in water beyond 1m.
