The best sound source we've found is a simple metal clicker, such as those made for dog training. They are made from spring steel, and emit a single sharp click when the steel is bent. Check a pet store and ask for a "dog training clicker." We've see...
On both radiation monitors we use a 2.2k pull up resistor in our cables to get a 5-volt signal that goes low for each event.
The RM-BTD output is an open collector with a pulse width of 40 microseconds. When used with a 2.2k pull up resistor, we g...
You cannot use MPLI for Windows program with Windows NT, Windows 2000, Windows XP, or Vista. These newer versions of Windows have severe limits on the ability to access memory locations in the computer. This is part of the design, for security.

This sensor will only work with Pasco's Pasport interfaces and can not be used with a Vernier interface. The Pasport line of sensors does not have an adapter, and Pasco says they have no plans to create one. Note that Pasport sensors can also not be...
Extension cables for our sensors are listed below. They are 2 meters long. They have been divided by sensor type
Digital Sensors (Motion Detectors, Photogates, and Radiation Sensors):
Digital Extension Cable (EXT-BTD)
Analog Sensors (Temperature, P...
According to the documentation provided by Logitech, the Logitech QuickCam Communicate Deluxe does not work with Macintosh computers.
However, in our tests this model does work on Macintosh. Unfortunately, Logitech changes their model numbers and ...
In the past Vernier used to develop computer simulation software. We currently focus on sensors, software and curriculum to facilitate real-world data collection in the classroom.
There are many sources available for science simulations and they keep...

When using the ProScope with a microscope and a computer, the microscope tube adapter (BD-MTA) requires adjustment before an image can be observed.
To adjust the tube adapter, the following steps are required:
1. Connect the Proscope to the compute...
The listed range of our thermocouple is -200 to 1400 Celsius. The Flinn catalog (p 205 of 2004 edition) lists temperatures up to about 1600 C. These temperatures are, we think, measured optically.
In our tests with our thermocouple in bunsen burn...
