The anemometer consists of an impeller that contains a magnet, and there is a magnetic field sensor just below the impeller that reads how often the magnetic field changes. This is then calibrated to read the correct wind speed.
Since it is a mag...

In September 2012, we updated the Conductivity probe with a new calibration on each switch setting to optimize it for small improvements in the hardware.
Pre-Sept 2012 Calibration values:
Low Setting = 65.7 uS/cm
Middle Setting = 847.2 uS/cm
...
The accuracy is ±2% of reading or ±3°C, whichever is greater @ 18 to 28°C ambient operating temperature.

If your CO2 Gas Sensor no longer auto-IDs and is still under its 5-year warranty, you can return it to Vernier for inspection (see below). If it is a mechanical problem, it will be fixed at no charge under the warranty. If, however, it is determined ...
We haven't sold the Student Radiation Monitors for several years. Although we are often able to repair sensors outside of their 5-year warranty, we no longer have the parts to complete this repair.
If you are interested in replacing your radiation...
Yes. Traditionally, a solution of sodium sulfite is used as the zero-oxygen calibration solution but this is NOT recommended for the Optical DO Probe. A zero-oxygen calibration solution can be created by bubbling nitrogen gas into distilled water.
...
No. The Optical DO Probe is not affected by the presence of hydrogen sulfide and other gasses that interfere with the traditional electrochemical method. ...
First, we need to determine if there really is mold inside the shaft of the sensor--it might be a precipitate rather than mold. To test this, place the sensor in ~150 mL of warm water and let it sit in the warm water for 15-20 minutes. If the amount ...
The best way to prevent damage to the Colorimeter is to prevent a spill from happening in the first place. Using lids on the cuvettes is the best way to accomplish this.
There are various models of Vernier Colorimeters (see What model Colorimeter...
