Hanna HI9147-04 Dissolved oxygen meter

Hanna HI9147-04 Dissolved oxygen meter

The Hanna HI9147-04 Dissolved oxygen meter  is a highly durable and accurate dissolved oxygen (DO) meter specifically designed for demanding environmental and aquaculture applications. With a wide measurement range, automatic temperature compensation, and manual calibration in saturated air, this meter ensures precise readings even under challenging field conditions. Its robust construction and exceptional battery life make it a reliable tool for long-term outdoor use.

Features

• Wide Measurement Range
  Measures dissolved oxygen up to 50.0 mg/L (ppm) and 600% saturation, making it suitable for both high and low oxygen environments.

• Automatic Temperature Compensation
  Provides consistent accuracy with automatic compensation over a wide temperature range from –5.0°C to 50.0°C (23°F to 122°F).

• Manual Calibration in Saturated Air
  Simple and reliable one-point calibration method using water-saturated air—ideal for field conditions with no need for calibration solutions.

• Salinity and Altitude Compensation
  User-adjustable salinity (0–51 g/L) and altitude (0–4000 m) compensation improve accuracy in seawater and high-altitude environments.

• Extended Battery Life
  Operates for up to 1,000 hours on three AAA batteries, making it perfect for extended field deployment without frequent recharging.

• Rugged and Portable Design
  Compact, weather-resistant casing and low-profile body provide durability and ease of use for both indoor and outdoor applications.
