OXY7 Portable Oximeter with Polarographic Sensor – Measure Oxygen, Temperature, and Barometric Pressure

Professional Dissolved Oxygen Meter for Accurate Field and Laboratory Use


The OXY 7 Portable Oximeter is a high-precision instrument designed for measuring dissolved oxygen (DO), temperature, and barometric pressure. Equipped with a polarographic DO7/3mt sensor and a 3-meter cable, this device offers reliable performance for environmental monitoring, water quality testing, aquaculture, and laboratory applications.


Key Features:

  • Simultaneous display of dissolved oxygen and temperature
  • Automatic atmospheric pressure compensation
  • Manual salinity compensation for increased measurement accuracy
  • Splashproof IP57 rating – ideal for fieldwork in demanding environments
  • Dual oxygen measurement modes:
  • Dissolved O₂ saturation (%)
  • Dissolved O₂ concentration (mg/L or ppm)


Advanced Sensor Technology

The included DO7/3mt polarographic probe features an integrated temperature sensor for Automatic Temperature Compensation (ATC). This ensures high-accuracy measurements regardless of environmental temperature fluctuations. The oxygen sensor uses a BNC connector, while the temperature sensor connects via an RCA plug for easy setup.


How It Works:

The probe utilizes a polarographic sensor with a precious metal anode and cathode housed within a gas-permeable membrane filled with electrolyte solution. Oxygen molecules pass through the membrane and react with the electrolyte, producing a signal proportional to the dissolved oxygen concentration. This signal is processed and displayed instantly on the oximeter.


Ideal Applications:
  • Water treatment and quality control
  • Aquaculture and fisheries
  • Environmental field research
  • Laboratory analysis of water samples


Get reliable and accurate oxygen measurements anywhere with the OXY 7 Portable Oximeter – your trusted tool for precise dissolved oxygen monitoring.
