30-Volt Voltage Probe

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.

The Digital Control Unit (DCU), combined with features in Logger Pro, makes control of electrical devices, such as buzzers, lights, motors, pumps, and relays, both straightforward and flexible. The DCU is a great way to introduce hands-on STEM and engineering projects.

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 Vernier Go Wireless Heart Rate is ideal for continuously monitoring heart rate before, during, and after exercise or while a person is stationary. Data are wirelessly transmitted to iPad, LabQuest 2, or other mobile devices that are Bluetooth® Smart Ready. It is simple and easy to use, displays live heart rate readouts before data collection, and is easy to clean and share between students.

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 Barometer can be used to measure and monitor atmospheric pressure. It works well for conducting weather studies or experiments that involve pressures close to normal atmospheric pressure. It can also be used as an altimeter if you have a portable interface.

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 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
