Vernier Anemometer

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The Mini GC Plus has been replaced by the Go Direct Mini GC.

The Mini GC Plus is a portable instrument for separating, analyzing, and identifying substances contained in a volatile liquid or gaseous sample. The Mini GC uses Air as its carrier gas so no external gas cylinders required.

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.

This sensor is used to measure voltages in the range of -30 to +30 volts

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 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 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.

Ideal for most acceleration experiments. Use it for studying the one-dimensional motion of a car (real and toy), lift, pendulum bob, or amusement park ride.

• Range: -50 to +50 m/s2
