Company History for RainWise

RainWise Inc. is a privately owned company incorporated in Pennsylvania in 1974.  The company name derived from our original product, the Remote Reading Tipping Bucket Rain Gauge.

In 1981 we moved to Bar Harbor, Maine and the development of a new line of electronic consumer weather instrumentation began with the WS-1000, the first digital weather station.

In 1985 the company built a new manufacturing/showroom facility in downtown Bar Harbor.

In 1991 the success of the consumer-based instrument line led to the development of an industrial line. The industrial equipment quickly became recognized for its customizable configuration, NIST traceability and, unheard of at the time, 5-year warranty.

In that same year, the General Service Administration awarded RainWise with a GSA contract. Under this contract, our products are available to over 700 Government agencies.

In 2020, RainWise was acquired by Nielsen-Kellerman, joining their other top Weather and Environmental Instruments brands.

In 2021, RainWise relocated to Nielsen-Kellerman's production facility in Boothwyn, PA.

Today, RainWise is proud to continue producing American-made products. The prevailing attitude of each and every employee is consistent throughout…make the best product to the best of your ability and stand behind it. The product will and always has spoken for itself.
