Both Pasco and Vernier have made many different sensors and interfaces in the last 20 years, so there is no simple and quick answer to this question. This document is meant to answer most common questions. If you have a compatibility issue that is n...
Nitrate Ion-Selective Electrode (NO3-BTA)
Specifications and User Guide
Troubleshooting
Primary Test: Check the raw voltages while calibrating in the standards. The high (100 mg/L) should be around 1.6 volts. The low (1 m...

Primary Test: Check the raw voltages while calibrating in the standards. The high (1000 mg/L) should be around 1.9 volts. The low (10 ...
Do not disassemble the probe for this type of cleaning. Swirl the tip of the probe in a 1:10 dilution of household bleach with water for ~10 seconds. Rinse well with DI water. NOTE: Do not submerge the entire probe. The "handle" is not waterproof....

Standard cleaning is best done with DI water. If sterilization is needed, use ethyl alcohol (typically >90%) or isopropyl alcohol (typically 60-70%) and swirl in solution for ~10 seconds. Then rinse vigorously with DI or tap water and recondition in ...
The only disadvantage of the Vernier Optical DO Probe (ODO-BTA) is that it costs more. It is both easier to use and more accurate than the older Dissolved Oxygen Probe (DO-BTA). The chart below shows a feature comparison.

Vernier LabQuest sensors - those with order codes ending in -BTA and -BTD - are designed to be used with Vernier interfaces and software. When used with a Vernier interface and software, you simply plug the sensor into the interface, connect the inte...
Yes. The Optical DO Probe uses an optical property to measure DO in a water sample. As a result, this probe does not interfere or have compatibility issues with pH, conductivity, salinity probes, or ISEs.
Note that there are some probes, includin...
