GLOBE Certification for Vernier Sensors!

Many of our customers participate in the GLOBE Program. This excellent, world-wide, hands-on, program gives primary- and secondary-school students the opportunity to learn science by doing science. Students participating in GLOBE take scientifically valid environmental measurements and report them to a publicly available database. Protocols and instruments are required to meet rigorous specifications in order to ensure the highest quality standards for data collection. GLOBE scientists have tested four Vernier sensors, Dissolved Oxygen Probe, pH Sensor, Stainless Steel Temperature Probe, and Conductivity Probe, and found them to be acceptable for GLOBE applications. GLOBE now plans to develop materials that detail the use of these probes to collect GLOBE data and hopes to have these available by this Fall. Stay tuned to the Vernier and GLOBE (www.globe.gov) web sites for further developments.
