About Hobi Services

Hobi Instrument Services (Hobi Services for short) was founded to support equipment manufactured by HOBI Labs, Inc., as well as to manufacture new HydroScat instruments with improved designs.

David Dana, founding chief engineer of HOBI Labs and expert on all its products, formed Hobi Instrument Services as an independent limited liability company in May, 2013.

As of 2024, Hobi Services supports only HydroScat-2, -4, and -6 models, on a custom basis.

From 2013 to 2023, Hobi Services supported all HydroScat backscattering sensors, the full line of HydroRad in-situ radiometers, HydroDAS data acquisition systems, a-Sphere in-situ spectrophotometers, Gamma transmissometers, and related equipment, with rigorous backscattering calibrations, radiometric calibrations traceable to NIST standards, pressure testing, temperature cycling, and comprehensive repair services.

Hobi Services is located in the beautiful Puget Sound area of Washington state, nestled between the Olympic and Cascade mountain ranges, near the shore of Lake Washington and the city of Seattle.
