Lab Expo Dissolved Oxygen Tester units are designed for measurement of oxygen concentration in water-based testing workflows. The range supports dissolved oxygen analysis from 0.0 to 20.0 mg/L with accuracy up to ±0.5 mg/L and oxygen saturation measurement from 0.0 to 200.0%. Portable tester configurations enable routine monitoring across field and lab environments. Suitable for water quality assessment, aquaculture operations, environmental testing, and process applications requiring controlled oxygen evaluation.
FAQ for Dissolved Oxygen tester
1: What is a Dissolved Oxygen Tester used for?
Dissolved Oxygen Tester measures the amount of oxygen dissolved in water, which is essential for assessing water quality in wastewater treatment and laboratory analysis.
2: What is the Auto-Hold function on a Dissolved Oxygen Tester?
The Auto-Hold function automatically locks the display once the reading becomes stable, allowing users to view and record the final value without needing to constantly monitor the screen.
3: Can I use the tester in wet or rainy conditions?
Absolutely, the waterproof design ensures reliable performance even in rain, splash-prone areas or when the tester is accidentally dropped into water.
4: What does the battery indicator on the Dissolved Oxygen Tester do?
The battery indicator displays the current battery level, allowing users to monitor power status in real-time and avoid unexpected shutdowns during use.
5: What type of sensor does the Dissolved Oxygen Tester use?
This tester uses a polarographic sensor which measures dissolved oxygen through an electrochemical reaction between a cathode and anode in the presence of oxygen.
