Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If
If any liquid gets into the device, immediately power the unit down (press and
hold the power button for more than three seconds). Disconnect the sensor and
charging cable, and remove the battery. Allow the device to dry thoroughly
before attempting to use the device again. Do not attempt to dry using an
external heat source.
Note:
Damage due to exposure to liquids is not covered under warranty.
How the Sensor Works
Go Direct Ethanol Vapor uses a metal oxide semiconductor to detect ethanol
concentrations in the air. Ethanol vapor reacts with the metal oxide and is
consumed in a reaction that reduces the resistance of the sensing element. A
circuit converts the change in resistance into an appropriate ethanol
concentration. The sensing element is very sensitive to ethanol vapor and also
responds to a wide range of volatile organic compounds. It also responds to
water vapor and carbon dioxide gas but to a lesser degree.
Troubleshooting
l
Very important:
Do not place the sensor into any liquid. The sensor is
designed to measure ethanol vapor above an aqueous sample.
l
For best results, allow the sensor to warm up for 5 minutes before taking
measurements.
l
Built-in temperature, pressure, and humidity compensation are not provided.
For best results, calibrate before use and use at room temperature.
l
The recommended sampling rate is 1 sample per second or slower for this
sensor. This allows the sensor to average a set of measurements before
reporting a value. Gas must diffuse to the sensing element to detect any
changes in concentration. Because diffusion of gases is a slow process, there
can be a delay in response time.
l
When using a fermentation chamber, use a clamp or an electrode support to
adjust the position of the sensor tip by moving the shaft up or down as
necessary.
l
The 250 mL Nalgene Bottle and #6 stopper that are included can be used as
a fermentation chamber. Wrap the stopper around the sensor shaft, rather
than sliding it on or off. Place the probe with the stopper into the bottle, and
then gently twist the stopper. Verify that the sensor tip is not immersed in
fluid. For best results, place the chamber on a stir plate and use a magnetic
stir bar to keep the sample moving.
l
To collect data in a controlled environment and also use our one of our CO
2
gas sensors, we recommend purchasing the BioChamber 2000 (2 L capacity).
This BioChamber has a second, grommetted opening so that you can insert
two probes at once.
