Use an Electrode Amplifier to collect data from almost any electrode that has a BNC connector. This includes electrodes from Vernier such as our pH electrode, or third-party electrodes, such as pH, ISE (ion-selective electrode), or ORP...

Most of our sensors have cables that are 1.5 m long. There are times, however, that you may wish to have a longer cable. The Analog Sensor Extension Cable can be used with any Vernier sensor that connects to an analog channel labeled...

You can use our Chest Belt Transmitter in conjunction with the Hand-Grip Heart Rate Monitor’s receiver for a hands-free option of measuring heart rate. This item has been discontinued and once our stock is run out we will not be able to...

The BioChamber 250 is a 250 mL Nalgene bottle that can be used with a CO2 Gas Sensor and an O2 Gas Sensor to monitor gaseous carbon dioxide and oxygen levels simultaneously in a closed system. The BioChamber is useful in experiments such...

The BioChamber 2000 is a 2000 mL plastic chamber that can be used with a CO2 Gas Sensor and an O2 Gas Sensor to monitor gaseous carbon dioxide and oxygen levels simultaneously in a closed system. The BioChamber 2000 is particularly...
