Hanna HI98193 Waterproof Portable Dissolved Oxygen and BOD Meter

Description

A Rugged Device For Demanding Tasks

The Hanna HI98193 is a professional, portable dissolved oxygen (DO) meter designed for a wide range of demanding applications. Its robust, waterproof enclosure is rated to IP67 standards, making it exceptionally durable and reliable in harsh environmental conditions. This meter is engineered to provide precise measurements of dissolved oxygen, along with barometric pressure, temperature, and is capable of performing calculations for Biochemical Oxygen Demand (BOD). The device is supplied in a rugged carrying case with custom thermoformed inserts, ensuring all necessary accessories are securely and conveniently stored for fieldwork.

The HI98193: Designed for Accuracy

Accuracy and precision are critical in dissolved oxygen measurements, and the HI98193 addresses this by incorporating several key compensation features. The device has an extended DO measurement range, from 0.00 to 50.00 mg/L (ppm) and 0.0 to 600.0% saturation. To ensure accurate readings, it automatically compensates for salinity, pressure, and temperature. The built-in barometer offers automatic pressure compensation, a feature that can be calibrated to a reference barometer. Temperature compensation is handled by a sensor built into the probe, which can be calibrated at one or two points. Additionally, users can manually enter salinity values for accurate measurements in saline environments.

Advanced Calculations For Comprehensive Analysis

The HI98193 goes beyond simple DO measurement by offering built-in methods and calculations for more complex analyses. It can determine Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR). For BOD, the meter calculates the value in mg/L from the difference between the initial and final dissolved oxygen concentration readings. OUR is measured in mg of oxygen consumed per liter per hour , while SOUR is measured in mg of oxygen consumed per gram of volatile suspended solids per hour. These built-in capabilities make the HI98193 an invaluable tool for environmental and wastewater applications.

Seamless Integration and Data Management

The HI98193 is designed for ease of use and efficient data management. Its “log-on-demand” feature allows users to store up to 400 samples with a simple press of a button. This stored data can be easily transferred to a PC using an opto-isolated micro-USB cable and the HI92000 software. This connectivity ensures that data can be easily reviewed, analyzed, and stored for record-keeping and reporting. The GLP (Good Laboratory Practice) features also provide calibration data, including the date, time, pressure, and temperature of the last calibration, ensuring adherence to quality control standards.

Intuitive Design for Effortless Operation

The user interface of the HI98193 is built for intuitive, one-handed operation. It features a combination of dedicated and virtual keys, providing easy access to functions like calibration, help, and data logging. The high-contrast, backlit graphic LCD display is easy to read in various lighting conditions, from bright sunlight to dimly lit areas. Additionally, a dedicated “HELP” button provides on-screen, context-specific assistance at any time. The quick-connect probe design, with its DIN connector, simplifies attaching and removing the probe, making fieldwork more efficient.

Versatile Applications in Many Fields

The Hanna HI98193 is a versatile tool with a wide range of applications, especially in the environmental, water, and wastewater industries. Its ability to measure dissolved oxygen and perform BOD calculations makes it essential for monitoring water quality in lakes, rivers, and treatment plants. The device’s waterproof design and rugged construction allow it to be used in challenging field conditions, such as monitoring aquaculture systems or in food manufacturing. With its comprehensive features, the HI98193 provides the data needed for accurate and reliable water quality analysis, from basic measurements to complex calculations.

Polarization and Membrane Caps Made Simple

The HI98193 features an automatic polarization function for its polarographic probe, ensuring the probe is ready for use immediately upon startup. This eliminates the need for manual waiting periods, streamlining the measurement process. The HI764073 probe uses ready-to-use, field-replaceable PTFE preformed membrane caps, which makes maintenance and replacement straightforward. This design choice is a testament to Hanna’s focus on user convenience and ensuring the device is always prepared for accurate measurements.

The Power of Precision and Portability

The Hanna HI98193 represents a perfect blend of professional-grade precision and practical portability. Its comprehensive feature set, including automatic compensations for temperature, pressure, and salinity, ensures highly accurate readings in diverse conditions. The ability to perform advanced calculations like BOD, OUR, and SOUR, combined with a user-friendly interface and robust data management capabilities, makes it an indispensable tool. The device’s rugged, waterproof design guarantees its longevity and reliability in demanding environments, solidifying its position as a top choice for professionals who require a dependable and versatile dissolved oxygen meter.
