DO5021 for internal applications or usage covered from the elements

The DO5021 measures dissolved Oxygen levels in tanks, ponds and lakes and can turn on an installed aeration system when it is required thus saving energy. This cost-effective system can ensure DO2 levels are maintained, and fish are kept at their best and in an unstressed state. The system can also be used to control bottled O2 supply in both static and transportation tanks.

The system comes with an integral 16A socket to drive existing aerators as required. Low DO2 alarm levels can be user adjusted to desired trigger levels. The display provides readings in mg/l, temperature and %SAT levels. Simple 1 point calibration.

The DO5021 optical probe is supplied with 8 mtrs cable as standard but can be increased with connectors or single length at the factory. 

The DO5021 optical DO2 sensor, popularly known as luminescent DO2 sensors (LDO), measures dissolved oxygen concentration in water based on the quenching of luminescence in the presence of oxygen. 

Advantage over conventional probes:

1. – Minimal calibration required. 
2. – No sensor drift. 
3. – Fast speed of response 
4. – Minimized installation and maintenance time.
5. – Resistant to abrasion and photobleaching.
6. – Minimal loss of performance, 2-year sensor cap life
