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. Do you need an interface? Why not go for our Heart Rate Human Physiology Kit?

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 Instrumentation Amplifier monitors voltages from 20 mV to 1 V (DC or AC). It has several switch settings to allow you to select the best gain and includes auto-ID functionality for each of the six ranges. Input bandwidth of 10 kHz allows the capture of higher frequency signals. It is typically used to amplify the chart recorder or analog output of any instrument, such as a third-party gas chromatograph.

Use the Drop Counter to perform accurate, automatic titrations. Record the number of drops or calibrate the drop size to record volume of titrant added during a titration. Logger Pro software can automatically convert the number of drops into volume. The Drop Counter can be used for conductimetric or potentiometric titrations using our Conductivity Probe, Ion-Selective Electrodes or any electrode with a 0 to 5 volt output.

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.

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.
