How does Vernier Conductivity Probe work?

The Vernier Conductivity Probe measures the ability of a solution to conduct an electric current between two electrodes. In solution, the current flows by ion transport. Therefore, an increasing concentration of ions in the solution will result in higher conductivity values.

What do you measure using the Vernier probes?

The Vernier Optical DO Probe is a luminescence-based optical dissolved oxygen sensor. It can be used to measure the concentration of dissolved oxygen in water samples tested in the field or in the laboratory. Note: Vernier products are designed for educational use.

What is a conductivity probe used for?

The Conductivity Probe can be used to measure either solution conductivity or total ion concentration of aqueous samples being investigated in the field or in the laboratory. Conductivity is one of the most common environmental tests of aquatic samples.

How do conductance probes work?

The Vernier Conductivity Probe measures the ability of a solution to conduct an electric current between two electrodes. In solution, the current flows by ion transport. Therefore, an increasing concentration of ions in the solution will result in higher conductivity values. This current is converted into a voltage.

How does do probe work?

The probe measures dissolved oxygen by emitting a blue light that causes the sensing element to luminesce or glow red. When no oxygen is present, the luminescence signal is at its maximum. As oxygen is introduced, luminescence decreases.

How does oxygen probe work?

In an electrochemical DO sensor, dissolved oxygen diffuses from the sample across an oxygen permeable membrane and into the sensor. Once inside the sensor, the oxygen undergoes a chemical reduction reaction, which produces an electrical signal. This signal can be read by a dissolved oxygen instrument.

What is the accuracy of a vernier?

The accuracy of a measurement by Vernier Calipers is defined by how near it is to the actual or true value, according to ISO 5725-1. In the case of multiple measurements of the same object, the accuracy takes into account the effect of random and systematic errors.

What is vernier Logger Pro?

Logger Pro 3.8.4 is a software program developed by Vernier Software & Technology. The primary executable is named LoggerPro.exe. The setup package generally installs about 8 files. Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows 8.

What is vernier protractor?

The vernier protractor is used to measure angle . This instrument is graduated to read in increments of 5-minutes of arc.
