There are two issues here:
1) Solutions that are difficult to measure
2) Solutions that will damage the sensor
Solutions that are Difficult to Measure
The pH Sensor (GDX-PH, GDX-FPH, PH-BTA or FPH-BTA) will have difficulty measuring the pH of the fo...
For best results, use a Vernier Emissions Fiber (VSP-EM-FIBER).
For better results when not using an optical fiber:
Align the aperture directly with the light source. Misalignment can shift the measured wavelengths of spectral lines by as much as th...

Our Power Amplifier (PAMP) is a great option for driving a speaker, such as our Power Amplifier Accessory Speaker (PAAS-PAMP), or an AC circuit. The Power Amplifier requires a function generator to control it. Whenever possible, we recommend using th...
Yes, resonance in RLC circuits can be investigated with either the Vernier Circuit Board (discontinued)or the Vernier Circuit Board 2 (VCB2).
If using the Vernier Circuit Board, an inductor such as Inductor (IND) will be needed. However, the Verni...
Yes, we have a drop counter! The Vernier Drop Counter accurately records the number of drops of titrant added during a titration. The software can record volume in drops or mL, and can simultaneously record pH (pH sensor sold seperately). The Drop Co...
The body of Plastic 2-Way Valve (PS-2WAY) is polycarbonate and the handle is high density polyethylene. This is true for the older 3-way valve (discontinued), as well.
The chemical resistance is good when using dilute acids, alkaline solutions, al...

Occasionally the motion encoder system will work as a ratchet, with readings only increasing or only decreasing. This is not a setting in Logger Pro or LabQuest App; no software change can create the problem. The issue is between the detectors on the...
