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.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know when to replace my alcohol sensor filter?\u003c\/h3\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eReplace 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.\u003c\/p\u003e\n\n\u003ch3\u003eWhat types of samples require the alcohol sensor and filter?\u003c\/h3\u003e\n\u003cp class=\"my-2 [\u0026amp;+p]:mt-4 [\u0026amp;_strong:has(+br)]:inline-block [\u0026amp;_strong:has(+br)]:pb-2\"\u003eAny 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\/\",\n  \"@type\": \"Product\",\n  \"name\": \"Heathrow Scientific 47001-ALFILTER Replacement Alcohol Sensor Filter, Pack of 10\",\n  \"description\": \"Alcohol-resistant replacement sensor filters for the Heathrow Scientific electrical resistance sensor.
