As Krishnan puts it, “we have to use nature's tools to study nature.” We have just begun to learn how to use nature's pH meter. Modi, S. et al. A DNA nanomachine that maps spatial and temporal ...

and provide added data like soil pH, temperature, and sunlight exposure. Only a lab test can truly assess the composition of your soil, but a moisture meter is one garden tool that can give you a ...

In addition to pH, ion, voltage and temperature measurement, the combined 781 pH/Ion Meter also offers an automatic stirrer control, a multi-point calibration with up to nine buffers (pH mode), a ...

Also, these meters are two in one in the sense that they can measure on two channels at once. This implies parallel measurement of pH and conductivity with 914 pH/Conductometer, and parallel recording ...
