Each O2 Gas sensor and Go Direct O2 Gas sensor ships with a 250 mL bottle to use as a respiration chamber. Because of variation in the inner diameter of the bottles, the bottleneck may not fit snugly with the O2 sensor. If this is the case, we recom...

There are two conditions that can cause this issue with the Vernier Optical DO Probe. If you are measuring the rate of photosynthesis in the lab using an artificial light source, it could be light contamination. If you are doing a field experiment or...

As described by on the IB website, among the IB Physics standards are several prescribed lab practicals. One or more of these lab practicals appear in questions in the Paper 3 external assessment. As such, it is important to plan around them. For mo...

The first batch of Go Wireless® Link (GW-LINK, discontinued) had a firmware bug that affected how the device reads the auto-ID resistors in our sensors. If the Go Wireless Link reads the resistor incorrectly, it incorrectly identifies the sensor. ...

IB Chemistry standards for lab practicals are listed on this website from Diploma Programme, Chemistry teacher support material Teachers are required to develop a practical scheme of work (PSOW). Practical skills may be assessed as part of the exter...

Go Direct® PAR (Photosynthetically Active Radiation) (GDX-PAR) 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 Sta...

In general, older sensors from ULIs and Serial Boxes can be used with new interfaces using an adapter. The newer style sensors have a feature called Auto ID, and our software instantly recognizes them when connected. Older sensors do not have this fe...

SensorDAQ (SDAQ) is a lab interface for use with LabVIEW and engineering education. The analog output on SensorDAQ is on the screw terminal connections. It has a 0 to 5 volt output. There are two ways to make the connection from SensorDAQ to the...

Yes. We have a project from Dave's garage that lets you connect one Vernier sensor to Pachube. We call it VS2PB. Details on the application are below. It is available on request by sending a message to pachube@vernier.com. Part I. Introduction...

The Conductivity Probe (CON-BTA) is automatically temperature compensated between temperatures of 5 and 35°C. Note that the temperature of a solution is being read by a thermistor that extends into the space between the graphite electrodes. Readings...
