The clear storage bottle containing the damp yellow sponge provides better protection for the probe during storage. Remove the entire bottle to use the Optical DO Probe.
If you are conducting a one-point calibration, the clear storage bottle with...
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...
Debris on any PAR sensor lens will partially block the optical path and will lead to low readings. Dust and other organic deposits are best removed using water, or window cleaner. Never use an abrasive cleaner on the lens. Salt deposits can also accu...
The Vernier PAR Sensor is calibrated before shipping and should not need user calibration.
However, you can calibrate the sensor using the Clear Sky Calculator (www.clearskycalculator.com). The Clear Sky Calculator for Quantum Sensors reports the...
We do not recommend submerging the microphone in water. It is not intended for that use. We do not at this time sell a sensor designed for measuring sound under water....
In Lab #1 of the 2013 AP Chemistry lab book published by AP Central, the student is directed to measure % transmittance (%T) of a series of solutions of blue 1 food dye.
When using a Colorimeter, Logger Pro 3 defaults to displaying both %T and abs...
If the Energy Sensor seems to produce noisy readings proceed as follows:
1. Zero the Sensors on the VES while shorting out the Source terminals. Remove the short.
2. If connected to a wind turbine, try a more stable source like a battery or even a ...
The control knob on the Melt Station is held in place with two set screws. The drive size of the set screws is 1.5 mm. Vernier does not supply or sell a wrench for the set screws. However, you can purchase an inexpensive 1.5 mm hex wrench at any most...
If you purchased the Optical DO Probe prior to January 2015, the percent saturation setting has a range of 0-100%. This range can be expanded to measure between 0-300%. The process includes paying an upgrade fee and sending the probe to Vernier for a...
