Does seeing a company's extreme stress testing make you trust their everyday products more?
Fluke launched an 87V MAX digital multimeter 20 miles above Earth to test its durability in extreme conditions. The device returned after a 49-minute descent and passed all post-flight performance tests.
Why it matters
The test highlights the engineering standards and durability of industrial tools when subjected to harsh environmental pressures. It serves to demonstrate that the equipment can maintain reliability well beyond typical usage requirements.
The multimeter encountered temperatures near -76°F and atmospheric pressure of 0.87 kPa during its flight. It reached speeds exceeding 110 km/h during the descent before passing electrical and physical inspections in Norwich, United Kingdom.
The players
Fluke
An industrial tool manufacturer headquartered in Everett that has operated in the industry for 80 years.
The details
Engineers from the Everett-based company performed a comprehensive assessment at a calibration facility to ensure the device maintained accuracy for voltage, current, and resistance. This experiment informs Fluke's internal standards, which include testing CAT-rated equipment to 12,000 volts and setting internal altitude requirements to 10,000 feet.

Seasonal Patterns
This test pushes the limits of Fluke's internal altitude requirement for equipment, which is currently set to 10,000 feet. By successfully operating at 20 miles, the device significantly outperforms the benchmark set for standard industrial use.
Professional users can expect this level of extreme durability to translate into reliable performance in demanding, high-altitude or low-temperature work environments. This confirmation of tool integrity helps technicians ensure their equipment remains calibrated and functional under difficult conditions.
The takeaway
This successful test confirms that industrial-grade equipment is built to withstand environments far more volatile than standard job sites. Technicians should verify that their tools meet the specific environmental ratings required for their local project conditions.
