The Constant Current System is a DC power source with a built-in current probe designed for use in electrochemistry experiments, and as such eliminates the need for a separate power supply when performing electroplating and electrolysis experiments in Chemistry. It is capable of delivering 0.6 A at 5VDC
Use the Constant Current System to explore Faraday's law and determine Avogadro's Number.
Note: It can only be used in conjunction with its own built-in power supply. It cannot be used to measure the current of a circuit using a different power supply.

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 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.

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.

Our Hand-Grip Heart Rate Monitor is ideal for determining a person's heart rate while mobile or stationary. With this sensor, heart rate can be monitored during, or after, exercise. The sensor consists of wireless hand grips and a receiver module that plugs into any of our data-collection devices. The hand grips sense the electrical signals generated by the heart. For each pulse detected, a signal is transmitted to the receiver module, and the individual's pulse rate is calculated.

The Flow Rate Sensor can be used for environmental or Earth science studies. Flow rate data can be used to calculate the discharge value for a stream or determine the sediment transport of a stream. The Flow Rate Sensor includes 3 riser rods, which enable the impeller to be placed at fixed depths, and is equipped with a 5 m cable so your data-collection equipment can stay on shore. The Flow Rate Sensor also separates into four sections for easy transport and convenient storage.

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.
