Overview
The Thermo Orion A322 portable conductivity meter stands up to demanding field applications to deliver advanced readings in any location. Four AA batteries, included with purchase of the A322, provide over 800 hours of continuous operation. The waterproof, battery-operated meter displays reliable conductivity, TDS, salinity, resistivity and temperature readings on a large, backlit LCD screen that automatically locks in stable readings.
Storage
The Thermo Orion Star A320 series portable meters provide the largest storage capacity available for time-stamped data points, which can be conveniently uploaded to a PC through the meter's USB and RS-232 ports. Automatic or 1 to 5 point manual calibration makes instrument setup simple, while icons provide quick updates on battery life, electrode status and calibration information. Five reference temperature options are available to provide accurate data under any conditions. The simple button layout and on-screen messages also assist with calibration and explain setup menu choices.

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.

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania
Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Sustainable Data Collection: Climate Monitoring in the Caribbean
Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.
