Vendor lineage
Fluke - the meters and certifiers in every field bag
The 87 multimeter and the DSX CableAnalyzer - and a 2015 three-way split (Fortive, NetScout, NetAlly) worth knowing cold.
John Fluke Sr.'s 1948 instruments company became the generic word for the multimeter itself, and Fluke Networks made cabling certification an instrument category with legal weight. The 2015 Danaher deal split the story: enterprise visibility went to NetScout (the handheld line later reborn as NetAlly), while cable certification stayed Fluke Networks under Fortive - one company, three present-day homes.
The profile covers the 1948 founding, the 87, the DSP-to-DSX certification lineage, AirMagnet, the carefully-told 2015 split, and the Fortive present.
Founding stories
John Fluke Manufacturing Company
John Fluke Sr. - a Navy engineer and MIT graduate who had roomed with David Packard - built precision electrical measurement into a company whose name became the generic term for the instrument itself: to this day, field engineers 'grab the Fluke' regardless of what the label says. The rugged 87 multimeter (1988) is the archetype - drop-proof, trusted, yellow - and the Fluke Networks lineage carried the same DNA into cabling: if a link is certified, somewhere a Fluke tester signed for it.
The timeline
- The Fluke 87
The rugged true-RMS multimeter becomes THE meter - the industrial world's default instrument, still in production decades later, the physical embodiment of 'measurement you can bet on'.
- Into the cable plant
Fluke's DSP-series cable analyzers bring laboratory-grade measurement to structured cabling certification - pass/fail against the TIA/ISO standards, printed proof included; the category Fluke Networks comes to own.
- Danaher
Danaher acquires Fluke (~$625 million) - the instruments house joining the conglomerate whose portfolio moves will later split the Fluke Networks story down the middle.
Deal figure per the public record.
- AirMagnet
Fluke Networks acquires AirMagnet, the Wi-Fi analysis leader - spectrum and WLAN troubleshooting joining copper and fiber certification in the field bag.
- The split - read carefully
Danaher sells its communications businesses to NetScout (~$2.3 billion): Fluke Networks' ENTERPRISE visibility lines - OptiView, Visual TruView, AirMagnet - go with it. The cable-certification business does NOT: DSX CableAnalyzer, OptiFiber, and the certification franchise remain Fluke Networks. The handheld network-test line (LinkRunner, AirCheck) later leaves NetScout too - divested in 2018 and reborn as NetAlly in 2019.
Transaction structure per the public record; the NetAlly spin-out completed 2019.
- Fortive
Danaher splits; Fluke and Fluke Networks move to the new Fortive - where the yellow meters and the DSX certifiers continue, the standard instruments of the trades this site serves.
Flagship products and solutions
- Fluke 87 (and the meter line)The reference multimeter - the instrument 'Fluke' became the generic word for.
- DSX CableAnalyzer / OptiFiberThe structured-cabling and fiber certification standard - the tester whose report closes out installations worldwide.
- LinkRunner / AirCheck heritageThe handheld network and Wi-Fi test line born at Fluke Networks - continued today by NetAlly.
Key innovations
- Certification as a productFluke Networks turned 'does this link meet spec' into an instrument category with legal weight - the printed certification report is the cable plant's birth certificate.
- Ruggedness as a specificationThe 87's drop-proof, CAT-rated design made survivability part of accuracy - the field-instrument philosophy every hardened tool since inherits.
Main markets
Fluke (Fortive) remains the reference in electrical test; Fluke Networks owns cabling certification; the visibility and handheld branches live on at NetScout and NetAlly - one 1948 company, three present-day homes.
Analyst standing
- The pioneer entry closest to this site's readers' actual hands: the meter on the bench and the certifier in the bag - and the 2015 three-way split is worth knowing cold, because 'which Fluke' is a real procurement question.
