Dissolved Oxygen Analyzers
Dissolved Oxygen Analyzer – DO7 Sensor
Overview
Introducing the NEW Rugged Dissolved Oxygen Sensor exclusively for the meter DO7. The DO7 sensor utilizes lifetime-based optical fluorescence sensor technology to provide an extremely stable, precise and low maintenance dissolved oxygen sensor. Unlike traditional DO sensors, DO7 does not require membranes, stirring, and cleaning and allows deployment for many months without need for recalibration!
Conform to the following EU Directives & Standards:
- Low Voltage Directive 2014/35/EU
- Electromagnetic Compatibility Directive 2014/30/EU
- RoHS 2 Directive 2011/65/EU
- EN 61010-1:2010; EN 61326-1:2013
FEATURES & BENEFITS:
- High precision and accuracy. Measure absolute oxygen concentrations without field calibrations
- Integrates directly into the DO7 with Smart Sensor technology – “Plug & Play”
- No membrane, stirring/flow, or cleaning required
- Ultra-rugged construction – 316L, Titanium options
- Sapphire sensor window – extremely scratch resistant
- All of the optics and electronics are solid-state with no moving parts
- Optical sensor is not damaged by ambient light, unlike other luminescent DO technologies
- Fully compatible with PC software Delta-Phase ViewTM for easy setup and data logging
- Low sensitivity to fouling
- Fast response time
SPECIFICATIONS
Optical DO Technology
Sensor measurements are based on selected substances that can act as dynamic fluorescence quenchers. For example, for oxygen, if a ruthenium-complex is illuminated with a blue LED it is excited and emits back a red luminescent light with an intensity, or lifetime, which directly depends on the oxygen oncentration.
Lifetime based measurements are superior for both long-term (no drift) and fast response applications.
