Wittich & Visser

What Wittich & Visser does

Wittich & Visser BV is a Dutch engineering bureau (Ingenieursbureau) founded in 1924 and headquartered in Rijswijk, Netherlands, specializing in the supply and installation of scientific and meteorological instruments. The company operates a dual-sided model: (i) its own Meteo M&R program of affordable proprietary weather stations and sensors, and (ii) a value-added distribution business representing quality third-party brands — including Gill Instruments, Scintec, Radiometrics, Davis, Dynamax, Hansatech, PP Systems, Sentek, and Spectrafy — in the Benelux region. Product lines span weather stations, precipitation and storm sensors (including the Previstorm lightning warning system), radiation and sunshine sensors, temperature/humidity probes (Rotronic family), barometers (Setra family), agrometeorology/photosynthesis instrumentation (CIRAS-4, soil flux chambers, sap flow sensors, gas analyzers), turbulence scintillometers (BLS), and calibration instruments (HygroGen2).

The customer base is segmented across research institutions, agri- and horticulture, wind farm operators (IEC-61400 compliant installations), weather warning systems, HVAC/building management, and development projects in South Asia, East Africa, and the Middle East. Revenue mechanics are predominantly hardware sales (proprietary Meteo M&R + distributed brands) supplemented by professional services — calibration, repair, and maintenance — for which the company offers a proactive reminder system. GTM is sales-led through the corporate website (wittich.nl), direct enterprise sales, and participation in (inter)national tenders. The company has been operating continuously for over 100 years as an independent private limited company (bv) with 11–50 employees and no disclosed external investors.

Product overview

Wittich & Visser is an engineering bureau founded in 1924 specializing in scientific and meteorological instruments. Their product portfolio consists of physical hardware instruments rather than software or AI-enabled products. The core offering includes their proprietary Meteo M&R program of affordable weather stations and sensors, complemented by distributed brands including Gill Instruments, Scintec, and Radiometrics. The product range spans: weather stations (Davis Vantage Pro2, MetPak, Meteo M&R), precipitation sensors (Previstorm, ARG100, Hellmann, RSG, RSA, SBS), radiation and light sensors (SolarSIM-G, Blake-Larsen Sun Recorder, Campbell-Stokes, GS-WV, LP02, NR01, RA01, SR11), temperature and humidity instruments (Rotronic probes HC2-S3/S3H/S3-Heated/HC2A-S3, transmitters HF4/HF5, handheld meters HP21/HP22, HygroMet4, MP100A/400A, weather screens RS12T/RS24T, AC series), air pressure sensors (Setra 270/276/278/370/470), agrometeorology equipment (CIRAS-4, CFLUX-1, CPY-5, Drill & Drop, EXO-Skin, TDP, EGM-5, SBA-5, WMA-5, Pocket Pea, SRC-2, TARGAS-1), turbulence sensors (BLS Scintillometer), and calibration instruments (HygroGen2 HG2-S/HG2-XL). They also offer conventional weather instruments like thermohygrographs, barometers, and rain gauges for development projects. Services include calibration, repair, and maintenance for weather sensors with reminder systems.
