In October/November of 2018 we shipped some UVB Sensor (UVB-BTA) that were assembled with the label on the tube that says Relative Humidity Sensor (RH-BTA). They were sold as UVB sensors and came in bags labeling them as UVB sensors and they do work...
Go Direct® Ethanol Vapor (GDX-ETOH)
Specifications and User Guide
Troubleshooting
General: Press the power button on the sensor to turn it on. Connect your sensor as described in the Getting Started instructions for your d...
The Go Direct® Ethanol Vapor (GDX-ETOH) and Ethanol Sensor (ETH-BTA) should not be exposed to concentrations of ethanol greater than 3%. To determine the amount of ethanol produced from a standard fermentation you will need to dilute your sample ...
Vernier ethanol sensors work well between 0% and 3% ethanol. The standard calibration will give good change over time data, but for quantitative data, calibration will increase the accuracy of the readings near the top end of the range. ...
It may not be necessary to perform a calibration when using and of the Vernier ethanol sensors in the classroom.
If your experiment or application is evaluating the rate of ethanol production, such as determining fermentation rates with yeast, or...
If you want to use a Vernier CO₂ Gas Sensor and a Vernier ethanol sensor to show that CO₂ gas and Ethanol are both produced during fermentation, you should use the following protocol. Please note that you will need a BioChamber 2000 (BC-2000), a...
Two experiments that use Vernier ethanol sensors can be found on the web page for this sensor. Both experiments investigate fermentation and sugar metabolism using yeast. One exercise is written as a standard lab exercise. The second lab is written i...
All Vernier ethanol sensors will never give a reading of 0 in air because of the type of calibration formula that is used.
The minimum reading will typically fall within the following range:
Unit
% 0.007 - 0.010
ppt 0.07 - 0.100
...
No.
The Go Direct® Ethanol Vapor (GDX-ETOH) and Ethanol Sensor (ETH-BTA) are gas sensors that detect ethanol vapor. The sensors needs to be placed above a liquid sample. The use of Tape for Ethanol Sensor (ETH-TAPE) (one roll is included with...
All Vernier ethanol sensors need to warm up for 5 minutes before use. On first use, the ethanol sensor may need more than 5 minutes to warm up.
If the sensor is slow to warm up or respond you can do the following:
1 Expose the sensor to a dilu...
