Hanna HI9146-10 Microprocessor dissolved oxygen meter

The Hanna Hanna HI9146-10 Microprocessor dissolved oxygen meter is a portable, microprocessor-based dissolved oxygen (DO) meter designed for high-accuracy water quality testing in a variety of environments. With features such as automatic temperature compensation, altitude compensation, and one or two-point calibration, this instrument is ideal for professionals conducting field or laboratory DO analysis.

Features

• Wide Measurement Range with High Resolution
  Measures dissolved oxygen from 0.00 to 45.00 mg/L or 0.0 to 300.0% saturation, with high resolution at 0.01 mg/L and 0.1%.

• Automatic Temperature Compensation
  Compensates for temperature variations between 0°C to 50°C, ensuring accurate and stable readings in real-time.

• Altitude Compensation
  Adjustable altitude setting from 0 to 4000 meters (resolution: 100 m) improves DO accuracy in varying elevations.

• One or Two-Point Calibration
  Allows manual calibration at 0% using HI7040 zero oxygen solution and 100% in air for greater measurement confidence.

• Reliable Polarographic Probe
  Includes the HI76407 polarographic DO probe, engineered for durability and dependable performance in the field or lab.

• Compact and Durable Design
  Lightweight and easy to carry, with an ergonomic design and backlit display for use in low-light conditions.

• Extended Battery Life
  Operates on three 1.5V AAA batteries, providing up to 200 hours of use without backlight and 50 hours with backlight.
