Description

The HI98198 is designed for professional-level dissolved oxygen monitoring with minimal hassle. Using enhanced optical luminescence technology, the meter measures dissolved oxygen with high precision, automatically accounting for temperature (-5 to 50°C), barometric pressure (420–850 mmHg), and salinity (0–70 g/L). SmartCap technology ensures automatic cap recognition, long-life usage of up to one year, and proper alignment every time. GLP compliance allows access to the last five calibrations with date, time, pressure, temperature, and salinity values.

Equipped with the HI764113 optical DO probe, the meter features a durable ABS shell with stainless steel protective shield, a PVC sleeve for outdoor use, and a quick-connect DIN fitting for easy installation. The probe requires no membrane or electrolyte replacement, ensuring minimal maintenance. Field usability is enhanced with a large backlit LCD, autoend functionality, and a USB-C port for quick data transfer to computers or memory devices. The package includes SmartCap with RFID, zero oxygen calibration solution, beakers, batteries, carrying case, and full documentation, providing a complete ready-to-use solution.

Features

  • Optical DO Measurement:
    0.00–50.00 mg/L and 0–500% saturation with high accuracy
    (1.5% for 0–20 mg/L, 5% for 20–50 mg/L; 1.5% ± 0.1% for 0–200%, 5% for 200–500%).
  • BOD/OUR/SOUR Built-In:
    Eliminates manual conversions and calculations, providing ready-to-use oxygen demand metrics.
  • Automatic Compensation:
