A spectrophotometer can be set to measure % transmittance and/or absorbance over a wide range of wavelengths. Our Colorimeter can only measure four specific wavelengths produced by internal LEDs. The Colorimeter costs far less, but works for a more l...

Eddy Current Brake (DTS-ECB) Specifications and User Guide ASSEMBLY Insert the desired number of magnets into the Eddy Current Brake. The Eddy Current Brake connectors swivel to allow 4 mm of height adjustment when installed in a cart. When th...

In the older-style Colorimeter (rounded shape rather than square), the cuvette holder is a plastic insert that can be removed and replaced. The order code for the replacement cuvette holder is CUV-HOLD. To remove the cuvette holder from your Colo...

In early 2014, some KidWind kits included a 3V/200mA solar panel instead of a 2V/400mA panel. You can differentiate between the 2V/400mA and 3V/200mA solar panels by the arrangement of cells on the panel. The cells on a 2V/400mA panel are arranged 4...

This article refers to experiments using the KidWind 2V/400mA Solar Panel (KW-SP2V). We have recommended a load resistance for each light source listed below. Note that the recommendations are based on using a single 2V/400mA Solar Panel. If you ...

The (MBOT-SKIT, discontinued) comes with the mBot and 2 add-on packs: the Variety Gizmos Add-on Pack, and the Perception Gizmos Add-on Pack. The electronic parts list is as follows: mBot: Ultrasonic sensor Me line-follower sensor IR receiver Light ...

Yes, you can connect Vernier sensors to a LEGO NXT or EV3 (the EV3 is LEGO's newer model robot platform, the NXT is the older platform). The NXT Sensor Adapter (BTA-NXT) allows Vernier analog (BTA) sensors to be used with the NXT or EV3. To us...

In general, when using an energy sensor to measure the power output of a small solar panel such as the KidWind 2V/400mA Solar Panel (KW-SP2V), you will get higher power measurements with a specific resistance load compared with all other amounts of ...

This article refers to the Go Direct® Energy Sensor (GDX-NRG). The Vernier Energy Sensor (VES-BTA) does not have a warning LED. The warning LED (next to a triangle containing an exclamation point) is meant to come on when there is a measurable p...

This article refers to the following two sensors: Vernier Energy Sensor (VES-BTA) Go Direct® Energy Sensor (GDX-NRG) The short answer is, if you don't measure using a complete circuit that includes a load, your power (and therefore energy pr...
