Optical DO Sensor

The Broadsensor optical DO sensor is coated with a luminescent material. Blue Light from an LED strikes the luminescent chemical on the sensor. The luminescent chemical instantly becomes excited and then as the excited chemical relaxes, it emit red light. The red light is detected by a photo diode. The time it takes for the chemical to return to a relaxed state is measured by referring an independent red led light. Oxygen has a dampening effect on this reaction. The oxygen concentration is proportional to the time it takes for the luminescent material to return to a relaxed state.

Online Turbidity Sensor

BroadSensor measures turbidity with an fiber optics sensor. An 860nm light from the emitter enters the sample via fiber and scatters off particles in the water. The scattered light at 90 degrees,, enters a PD detector via fiber. This follows the nephelometric technique of measurement, and values are expressed in nephelometric turbidity units (NTUs). This follows the ISO7027 standard.

4-electrode Exposed Conductivity Sensor

Conductivity sensor is widely used around power sector, chemistry industry, environmental protection field, food safety field and marine studies. Our sensor increases a pair of driven electrodes, which can effectively avoid deviation and drift caused by polarization of electrode. Besides, we designed the conductance cell inside the sensor, so the maintenance intervals are much longer.
