Hanna Instruments HI-98193 Professional Waterproof Dissolved Oxygen and BOD Meter, Complete with DO probe
PC Interface - Download test results to a computer programmed with HANNA’s Windows® compatible software (HI-92000), directly from equipment via a USB port or a RS232 cable outlet.
Battery powered – Allows use away from a power source. Batteries are included with all battery operated products.When measuring dissolved oxygen, compensations for salinity, temperature and pressure are essential to improve the accuracy and precision of readings.
Salinity compensation allows for direct determination of dissolved oxygen in saline waters. Temperature compensation is automatic with the probes built-in sensor, which features a one or two-point calibration. Pressure compensation with the meter's built-in barometer can be validated against a reference barometer, and if needed, can be recalibrated in user-selectable units (mmHg, inHg, atm, psi, kPa, mbar). With the internal barometer, the HI-98193 is able to compensate for changes in barometric pressure so there is no need for charts, altitude information or external barometric pressure information.
Other features include measurement, methods and calculations for BOD, OUR and SOUR.
Quick connect probe
The HI-764073 polarographic dissolved oxygen probe features a quick connect DIN connector to make attaching and removing the probe simple and easy.
Data Logging
The HI-98193s log-on demand features allows users to store up to 400 samples that can be later transferred to a PC with the HI-920015 USB cable and HI-92000 software.
GLP and On-Screen Help
Comprehensive GL data is directly accessible by pressing the GLP key; the contextual help menu can be accessed to obtain on-screen information and assistance at the touch of a button.
