ECO 531 Dissolved Oxygen

Features:

✔ Modern and functional housing

✔ Waterproof (IP65 / IP67)

✔ Convenient adjustment at air on keypress

✔ Incl. galvanic oxygen sensor with temperature measurement

✔ 3-line display / overhead display on keypress

✔ Backlight

The dissolved oxygen meter with the maintenance-friendly galvanic sensor is an entry-level device suitable for everyday use, both concentration in mg / l (ppm) and saturation in percent can be read off directly without using tables. The adjustment automatically takes place at ambient air, simply by keypress. For field use in bodies of water, the use of a GSKA protective cap is recommended to protect the membrane.

Description

ECO531 – Waterproof dissolved oxygen meter (DO) with sensor (formerly G 1610)

The primary focus in the development of the new ECO 531 Dissolved Oxygen ECO-line was placed on the essential functions of the measurement technology.
Pure measurement with a focus on precision, speed and reliability and compact packaging enable an impressive price/performance ratio.
The devices also have impressive ergonomics, dust and water protection according to IP 65/67 and backlit display.
The ECO 531 an intelligent oxygen measuring device for fishery, fish breeding, aquarium, aquaculture and well water measurement applications.

The ECO 531 is a high-accuracy, user-friendly dissolved oxygen meter designed for aquaculture, environmental monitoring, water treatment, and laboratory applications. With a durable waterproof housing, automatic temperature and salinity compensation, and a replaceable galvanic sensor, the ECO 531 provides fast and reliable DO readings in both % saturation and mg/L (ppm).

Features:

Dual Measurement Modes
Displays DO in both mg/L (ppm) and % saturation.
High Accuracy and Stability
Galvanic sensor technology enables immediate use without warm-up.
Automatic Temperature Compensation
Ensures accurate readings across variable field conditions.
Salinity & Altitude Compensation
Manual correction for salinity and pressure enhances accuracy in diverse water bodies.
Long Battery Life & Portable Design
100 hours of operation with 4 AAA batteries; perfect for fieldwork.
Waterproof & Rugged
IP67-rated housing for reliable performance in wet or outdoor environments.
Replaceable Sensor Cartridge
Easy-to-maintain design reduces downtime and ensures long-term use.
