Comparison Between LuminOx Oxygen Sensor and Piccolo2 Sensor

CO2 Meter Inc, a customer of SST’s renowned and reputable sales partners in the US, was interested to know the comparison between the LuminOx Optical Oxygen Sensor and a more expensive oxygen sensor like PyroScience’s Piccolo2 sensor.

CO2 Meter, an Ormond Beach, Florida-based engineering company, specializes in the design and development of gas detection and monitoring systems, predominantly CO2. Earlier in 2013, the company started selling SST’s LuminOx Optical Oxygen Sensor, an offering that complimented its product portfolio.

Heinz Surbeck, President of Nucfilm GmbH in Switzerland, raised the question. He is a physicist working in the environmental monitoring field and headed the Swiss Federal Environmental Radioactivity Lab for 20 years. Mr. Surbeck also served as a Sensor Scientist/Lecturer at the Center for Hydrogeology at University of Neuchatel for 10 years and a lecturer at the Earth Sciences Dept of the ETH-Zurich.

In one of his company’s projects, Mr. Surbeck required oxygen sensors in order to help fish farms ease their supersaturation problems. This involved continuous monitoring of carbon dioxide, oxygen, and total dissolved gas pressure (TDGP) to find out why nitrogen partial pressures in the water above partial pressure in the atmosphere cause the trout fish to become sick (bubble disease).

I’m well equipped with optical oxygen sensors from PyroScience – the best you can have – but I’m always looking for new innovative sensors that may be cheaper than my ‘Rolls-Royce’.

In order to compare the sensors, Surbeck developed an experiment where both sensors were exposed to the air samples for a period of one hour. Serial output was first run through an Arduino PRO and then to a serial to USB converter for a display on a computer. During the test, Surbeck observed that the LuminOx Optical Oxygen Sensor yielded almost identical results to the Piccolo2 sensor.


While this test has not been repeated, the Piccolo2 sensor appeared to cost 10 times as much as the LuminOx Optical Oxygen Sensor. This makes SST’s sensor more suitable for researchers requiring an accurate and cost-effective way to determine oxygen levels.
