Water Activity Meter Replacement Alcohol Sensor Filter
The Heathrow Scientific 47001-ALFILTER Replacement Alcohol Sensor Filter protects the electrical resistance (alcohol) sensor from volatile compound damage during water activity measurement of alcohol-containing samples. Supplied in a pack of 10, these specialized filters are engineered to withstand exposure to primary and secondary alcohols, glycols, and other volatile organic compounds.
Compatible exclusively with the Heathrow Scientific electrical resistance (alcohol) sensor (47001-ASENSOR), these filters maintain sensor integrity when testing spirits, tinctures, cosmetic formulations containing ethanol, and pharmaceutical preparations with volatile solvents.

Laboratory Applications
Distilleries, cannabis testing laboratories, and pharmaceutical compounding facilities that measure water activity in alcohol-containing matrices require these specialized filters to protect the electrical resistance sensor. Without alcohol-resistant filters, volatile compounds can saturate standard filters and compromise measurement accuracy.

Frequently Asked Questions
Can I use standard sensor filters with the alcohol sensor?
No. Standard sensor filters (47001-FILTER) are not designed for volatile compound exposure. Using them with the electrical resistance alcohol sensor will result in premature filter saturation, inaccurate readings, and potential sensor damage. Always use the 47001-ALFILTER with the alcohol sensor.
How do I know when to replace my alcohol sensor filter?
Replace when the filter appears dirty, falls off, or when measurement times increase noticeably. Alcohol-resistant filters saturate faster than standard filters due to volatile compound absorption. Facilities testing multiple alcohol-containing samples daily should replace filters weekly or as measurement consistency declines.
What types of samples require the alcohol sensor and filter?
Any sample containing primary or secondary alcohols (ethanol, methanol, isopropanol), glycols, or strong aromas requires the electrical resistance sensor with this alcohol-resistant filter. Common applications include distilled spirits, beer and wine, pharmaceutical tinctures, cosmetic lotions with ethanol, and cannabis extracts.
