Ethanol Sensor

PS-2194

Included Parts

1. Amplifier

2. Probe

3. PTFE tape for membrane replacement (not pictured)

Additional Part Required

• PASPORT interface or datalogger

Related Parts

• Replacement probe (PASCO part 003-10338)

• Additional PTFE tape (720-062)

Quick Start

1. Connect the amplifier to your PASPORT interface.

2. Connect the probe to the amplifier.

3. If you are using a computer, connect the PASPORT interface

to it and start DataStudio.

4. Ensure that the membrane is installed and intact. There

should be no tears or discoloration.

5. Place the end of the probe in the gas above a solution con-

taining less than 3% ethanol.

6. Press or click the start button to begin recording data.

The probe stabilizes after about 10 minutes of warm up time.

Introduction

The Ethanol Sensor measures the concentration of ethanol in a

gas or indirectly in a liquid. The sensor’s probe contains a mate-

rial whose resistance decreases in the presence of ethanol. The

sensor translates this resistance into an ethanol concentration

measurement, which is recorded and displayed by the connected

computer or datalogger. The Ethanol Sensor is well-suited for

continuous recording and discrete measurements.

Precautions

• Do not expose the probe to gas containing more than 3%

ethanol, including the gas above alcoholic beverages.

Higher ethanol concentrations will deplete the sensing ele-

ment. Note that the gas above a liquid contains about the

same concentration of ethanol as the liquid itself.

• Ensure that the membrane is installed and intact before

using the probe. The membrane prevents the sensing element

from getting wet. If the sensing element accidentally gets

wet, rinse and dry it quickly. Note that the probe may be

degraded or destroyed.

• Do not immerse the probe. The membrane (if it is in good

condition) will protect the probe in case of accidental immer-

sion. However, the probe is designed for use in gas only.

Connecting the Parts

1. Plug the amplifier’s PASPORT connector into any port of a

PASPORT interface or datalogger.

2. Connect the probe to the amplifier.
