美國NK Nielsen-Kellerman?
Richard Kellerman和Paul Nielsen于1978年成立NK公司。Richard當時就職于施樂公司任物理化學家，受雇于Ted Naches開發一種新產品，用來簡化行駛于河上的舵手的許多工作。在施樂公司同事Paul Nielsen的協助下，Richard Lellerman堅信能發明一種綜合放大器、計時表、沖擊計等功能的簡易裝置。于是Cox-Box放大器誕生了。1984年，NK擴大了產品系列，相繼開發四類產品，并以此為基礎，把此四種產品做得更小，更輕，更易使用。 1996年，NK開發了氣象儀器，叫做Kestrel手持氣象儀，做為一般消費品投放市場。手持產品目前的種類有近十種。

Nielsen-Kellerman Company designs, manufactures and distributes waterproof instruments for active lifestyles and technical applications, including:

Kestrel? Pocket Weather Meters
NK Electronics for Rowing and Paddling
NK Soaring Instruments
Customer Service and Commitment

If you distill what we at NK do into one phrase, it would have to be that we design and manufacture products for… fanatics. Whatever our niche, we know our customers won’t forgive us for letting them down, and will tell their friends what they think of us, good or bad. We employ a fully-staffed customer support department, and when our customers call or email, we bend over backwards to keep them happy.

Every NK rowing product is covered by a full two-year warranty, and Kestrel products are covered by a five-year warranty. All products are further covered by a lifetime Customer Care warranty, providing damaged product replacement at a very generous discount. We know that convincing customers to purchase a product is just the first step—once you’re an NK customer, we want to keep it that way! We’re proud of our tremendous repeat and referred customer percentages and virtually non-existent return rate.

Innovative US Manufacturer

Committed to US manufacturing, NK has continually updated and modernized its manufacturing methods to remain cost-competitive. NK employs Lean Manufacturing and Toyota Production System methods throughout its plant. Cellular manufacturing ensures continual close quality control and inventory is managed by a pull/kan-ban system to enable rapid response to customer demand and a high on-time shipment rate. NK’s plant also features NIST traceable calibration facilities for every product we make, including a 20-foot tow tank.
