The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. This has many applications in chemistry, biology, and environmental science. The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to demonstrate diffusion of ions through membranes. Chemistry students are able to quickly investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Environmental science students use it to measure TDS, total dissolved solids.

Use the Dissolved Oxygen Probe to determine the concentration of oxygen in aqueous solutions in the field or in the laboratory. The Dissolved Oxygen Probe is great for biology, chemistry, ecology, or integrated science courses. It can be used to perform a wide variety of experiments to determine changes in dissolved oxygen levels, one of the primary indicators of the quality of an aquatic environment.

The Polarimeter can be used to measure chiral properties of optically active samples without chemically modifying or destroying the sample. This is a vertical polarimeter that uses a 589 nm LED, a fixed polarizer, and a manually rotated polarizer to detect changes in rotation of plane-polarized light in the presence of an optically active compound. Used with Vernier technology, students no longer have to determine the optical maximum with their eye but have a graph that shows a clear change in the light's polarization.

The CO2 Gas Sensor measures gaseous carbon dioxide levels in two selectable ranges of 0 to 10,000 ppm and 0 to 100,000 ppm (which covers human breath). Ideal for measuring changes in Carbon Dioxide levels during plant photosynthesis and respiration. You can easily monitor changes in CO2 levels occurring in respiration of organisms as small as crickets or beans! The CO2 Gas Sensor is easily calibrated using a calibration button. A chamber is included for running controlled experiments with small plants and animals. You may also wish to see our O2 Gas Sensor

Use the Ammonium ISE to measure levels of ammonium ions introduced from fertilizers. It can also indicate aqueous ammonia levels if sample solutions are acidified to convert NH3 to NH4+. The Ammonium ISE has a combination-style, non-refillable, gel-filled electrode. Like all other PVC ISE membranes, the membrane on the ISE has a limited life expectancy. However, the replaceable module of ISE allows you to simply discard the used membrane module, and replace it with a new one. Note: We recommend that you do not purchase ISE replacement modules too far in advance of their expected time of use as degradation occurs while they are stored on the shelf.

Use the High Current Sensor in experiments that involve currents larger than 1 A, such as solar panels, hand generators, and other alternative energy projects. The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit
