Hanna HI9142 Manual calibration dissolved oxygen meter

Hanna HI9142 Manual calibration dissolved oxygen meter

The Hanna HI9142 Manual calibration dissolved oxygen meter is a rugged, reliable, and easy-to-use dissolved oxygen (DO) meter designed for use in the field or laboratory. With manual calibration, durable construction, and automatic temperature compensation, it is ideal for environmental monitoring, aquaculture, and wastewater applications that require accurate oxygen measurement in water.

Features

• Accurate DO Measurements
  Measures dissolved oxygen from 0.0 to 19.9 mg/L with a resolution of 0.1 mg/L, providing reliable results for water quality monitoring.

• Manual Calibration
  Allows for 1 or 2-point calibration (zero and slope) for full control and flexibility in field conditions.

• Automatic Temperature Compensation
  Ensures consistent and accurate readings by automatically adjusting for temperature changes between 0 to 30°C.

• Rugged Polarographic Probe Included
  Comes complete with the HI76407/4 polarographic DO probe and a 4-meter cable, suitable for in-field submersion and high-humidity environments.

• Long Battery Life
  Operates on 4 x 1.5V AA batteries with up to 500 hours of continuous use, making it perfect for extended fieldwork.

• Compact & Durable Design
  Encased in a rugged housing with simple push-button operation, designed for use in harsh environments with 100% relative humidity tolerance.
