DrDAQ is a versatile instrument that connects to the USB port of any PC. Using the supplied PicoScope software it can be used as an oscilloscope, spectrum analyzer and signal generator.
It can be seen from Figure 2 that the oxygen level makes a steady fall over the 48 hours showing the effects of the respiration of peas.
Ensure that the DrDAQ data logger does not come into contact with the water.
Thymol can be halmful if swallowed, inhaled or absorbed through the skin.
