Hobo U26 Dissolved Oxygen Logger

Hobo U26 Dissolved Oxygen Logger

A logger that is optimal for monitoring the effects of dissolved oxygen in water on various aquatic environments!

The "Hobo U26 Dissolved Oxygen Logger" is a data logger that measures and records dissolved oxygen in water. The recorded data can be corrected using the correction program "Dissolved Oxygen Correction Assistant," which allows for correction calculations for sensor drift caused by factors such as salinity, atmospheric pressure, and biofouling. It is an ideal tool for monitoring the impact of dissolved oxygen in aquatic ecosystems and various water environments. 【Features】 ■ Very high cost-effectiveness (maximum accuracy ±0.2 mg/L) ■ Optical DO sensor with long-lasting calibration and minimal maintenance ■ Correction of drift caused by the influence of aquatic biofouling, etc. ■ Easy maintenance with user-replaceable sensor caps *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

Process Fluorescent Dissolved Oxygen Sensor (Water Quality Meter) RDO Pro-X

Process Fluorescent Dissolved Oxygen Sensor (Water Quality Meter) RDO Pro-X

Low maintenance, high stability and responsiveness, corrosion-resistant fluorescent dissolved oxygen sensor (manufactured by In-Situ, USA)

This is a simple and low-cost dissolved oxygen sensor that is ideal for applications such as industrial wastewater, aeration tanks, raw water management for food and beverage manufacturing, and fisheries research and aquaculture. While the conventional model RDO PRO required sensor cap replacement once a year, the RDO Pro-X has eliminated that regularity, resulting in lower maintenance (however, since the sensor cap is a consumable, replacement is still necessary).

Portable fluorescent dissolved oxygen sensor "Smart Roll RDO"

Portable fluorescent dissolved oxygen sensor "Smart Roll RDO"

Handheld fluorescent dissolved oxygen sensor using a smartphone.

The portable fluorescent dissolved oxygen sensor "Smart Roll RDO" is a fluorescent dissolved oxygen sensor compliant with US EPA standards. By combining it with your iPhone, iPod touch, or iPad and the dedicated app "iSitu," your smartphone quickly transforms into a display terminal. The sensor improves operability through wireless communication via Bluetooth. Maintenance is simple, requiring only an annual replacement of the sensor cap, and its stability has dramatically improved compared to membrane-type sensors. The housing is made of titanium, and a sensor guard is included as standard, making it suitable for demanding environments. Measurement data (CSV files) can be easily sent via email (requires a communication environment). This is a unique sensor that stands out from conventional portable sensors. For more details, please contact us or download the catalog.

[Information] A discussion on Dissolved Oxygen (DO)

[Information] A discussion on Dissolved Oxygen (DO)

In addition to manual analysis, there are membrane electrode methods and optical sensor methods that utilize sensors for the quantification of dissolved oxygen.

Dissolved oxygen refers to the amount of oxygen (mg/L) that is dissolved in water. The amount that dissolves in water increases with lower water temperatures and higher pressures. Under conditions of 1 atmosphere and 25°C, it is estimated that about 8 mg/L (saturated dissolved oxygen level) of oxygen can dissolve. This document provides detailed information about dissolved oxygen sensors, non-aqueous solvent electrodes, and other information related to dissolved oxygen. Please take a moment to read it.
