Questions & Answers
Which Thermo Orion RDO/DO meter stores more data logs?
The Star A323 stores 5000 points while the A223 stores 1000 and the A213 stores 2000.
Does this meter have an internal barometer?
Yes, the Star A323 RDO/DO portable meter has in internal barometer for barometric compensation. If the probe is submerged or in a pressurized vessel, the pressure can be entered manually.
What is the difference between the portable A223 and A323?
The Thermo Star A223 RDO/DO meter can log 1000 time-stamped data points and can only delete the last reading or all data points. The Star A323 can log 5000 time-stamped data points, can delete any chosen data point and can be set to log at set timed intervals.

Choosing The Right Thermo Portable For Your Project

With so many options in Thermo Scientific’s Orion Star A line, it can be difficult to narrow down which meter will best fulfill a project’s needs. One easy way to rule out some meters is by considering application type. For projects that rely largely on collecting samples in the field, a portable meter is clearly the way to go. But there’s still a handful of meters to choose from. To simplify making the right choice, we spoke with Ricki Hartwell, the global product manager for Thermo Scientific’s Orion Laboratory and Field Instruments. She recently shared her tips on choosing the right Thermo benchtop. Let’s take a look at her recommendations for selecting the right portable meter.

Going, Going, Gone: Endangered Species Recovery and Conservation

Across the planet, biodiversity and natural habitats are declining dramatically. Countless species of flora and fauna around the world are being listed as either threatened, endangered, or extinct. According to a 2019 UN Study , around one million species are already at risk of extinction. Unless action is taken to reduce the causes of biodiversity loss, many of these species could disappear within the next few decades. Invasive species, habitat destruction, pollution, and other environmental stressors are all major causes of biodiversity decline. While high biodiversity is synonymous with places like the Amazon Rainforest and the Great Barrier Reef, it can also be found locally.

CastAway Doubts about Conductivity, Depth and Temperature Monitoring

The Sontek CastAway-CTD is a castable device that measures conductivity, temperature and depth. The instrument has been used in the field for over a decade by oceanographers, limnologists, divers, fishers and educators. There have been few changes since the first iteration in 2010, showing that the instrument is durable and accurate without requiring new models.   The CastAway is the first conductivity, temperature and depth (CTD) instrument of its kind. While other CTDs are large and cumbersome to deploy, with cages and isolated sensors, the CastAway is a small, lightweight and easy-to-use instrument. Typical CTDs utilize pumps to ensure water flows over the sensors during deployment.
