It depends on the age of the sensor. Vernier O2 Gas Sensors manufactured after April 2007 can be refurbished with a new electrochemical cell, whereas sensors manufactured before then cannot. (The newer O2 Gas Sensors can be identified by the recessed...
For many years, we sold an adapter to allow old home-made photogates and many other odd digital signals to be sent into a LabPro or LabQuest interface. Unfortunately we no longer make these adapters. The schematic is available if you would like to ma...
The ME-9207, ME-9207A, and ME-9207B (different revisions of the same product) all have a single 1/4" stereo jack that connects to the ULI directly. To connect it to a LabPro or LabQuest interface, you need an HMP-BTD adapter. Note: It does not work...
In every case possible, the new style is compatible with the old style. Although the carts and tracks included in the Dynamics Cart and Track System (DTS) look different than the carts in the Vernier Dynamics System (VDS, discontinued), there are mor...
Resolved Issues
• Improved the identification of devices having a bad MAC address during an update
• Fixed an issue that prevented emails containing international characters from being sent from a LabQuest device
• Addressed an issue with th...
Vernier warranties cover products used by educational institutions only. Most Vernier-manufactured products carry a five-year limited warranty. Products manufactured by anyone other than Vernier are subject to the conditions of the warranty supplied...
A crack at the end of the clear storage cap (where the sponge is located) does not affect the functionality of the Vernier Optical DO sensor.
A crack can commonly occur due to over-tightening the end of the storage cap. When placing the storage c...
In general, we do not recommend changing the setting on the Rotary Motion Sensor (RMV-BTD) to "left-handed" as opposed to the conventional, "right-handed" orientation in which counter-clockwise (anti-clockwise) is measured as positive angle values. H...
In most cases it is not necessary to calibrate sensors; however, for optimum accuracy you may choose to calibrate them manually.
To perform any calibration, you will need one or more external references for your sensor. For example, to do a two-p...
In order to calibrate a pH Sensor, or to confirm that a saved pH calibration is accurate, you should have a supply of pH buffer solutions that cover the range of pH values you will be measuring. We recommend buffer solutions of pH 4, 7, and 10. There...
