Pico Technology announces the immediate availability of an oxygen in air sensor for its low-cost, educational data logger DrDAQ: broadening the range of experiments that can be conducted in schools.
Cambridge, UK — 24 February 2003 Pico Technology, specialists in PC-based instruments, has announced the immediate availability of an oxygen (O2) sensor for its popular, low-cost educational data logger DrDAQ. The sensor, which plugs into one of DrDAQ's two sockets for external sensors, can be used in a wide variety of experiments for the measurement of the percentage of oxygen present in a gas.
Mike Green, Pico Technology's Managing Director, comments: “By adding oxygen in air sensing to DrDAQ's capabilities, we've greatly increased the number of Biology, Chemistry, Physics and Science experiments that can be conducted in primary and secondary schools.”
Experiments for which the oxygen sensor and DrDAQ lend themselves particularly well include:
Green continues: “The above experiments are just a few of many in which oxygen in air measurement plays a crucial role. They are, like the experiments detailed on our DrDAQ web site, ideal for teachers aiming to deliver step-by-step tuition to science pupils. The experiments are easy to conduct and the results can be saved and printed for reports.”
DrDAQ simply connects to a laptop or desktop PC running PicoLog data logging software, converting the computer into a powerful, yet easy-to-use, scientific instrument. DrDAQ has three built-in transducers for measuring temperature, light and sound. It can also measure voltage and resistance.
DrDAQ also connects to any standard pH sensor. Its external sockets (Ext1 and Ext2) accept a number of Pico sensors for measuring relative humidity (RH), external temperature, the presence of a magnetic field and, now, oxygen. DrDAQ automatically detects sensor types, so when plugging the new oxygen in air sensor into either Ext1 or Ext2, the software displays the reading as a percentage.
Pico has posted a library of educational science experiments, written by science teachers and industry experts, at https://www.picotech.com/library/experiments.
Green concludes: “Although the experiments we detail can be conducted using traditional, bench-top test and measurement equipment, pupils and students often have limited access to such equipment. Which is why we recommend the use of PC-based instruments like DrDAQ.”
The oxygen in air sensor is available immediately and retails for £99.00 + VAT.
DrDAQ with PicoLog software retails for £59.00 + VAT
