Testo : What instruments for measuring and controlling laboratory environments?

Since 1957, Testo has been designing measuring instruments and monitoring solutions that safeguard laboratory and life science environments. Thermometers, hygrometers, CO? sensors, anemometers and data loggers: the brand covers the entire chain, from on-site checks to continuous monitoring with Saveris. GxP requirements, audits, traceability: Testo delivers reliable, fully documented and actionable measurements for R&D, QC, production and cold-chain logistics.

A pioneer in measurement since 1957

Founded in 1957 in Lenzkirch, in the heart of the Black Forest in Germany, Testo has established itself as a global player in handheld measurement and monitoring. Starting from its first electronic thermometer, the company has steadily expanded its expertise to temperature, humidity, pressure, airflow and indoor air quality. Its technological backbone rests on strong R&D and the Testo Campus in Titisee, a showcase for engineering and sustainability. With an international network of subsidiaries and partners, Testo combines local, on-the-ground support with global compliance. The subsidiary Testo Industrial Services provides accredited calibration and qualification services to meet the requirements of regulated industries and demanding laboratories.

Expertise and areas of specialisation

For laboratories, Testo delivers an end-to-end chain of trust — from spot measurements to 24/7 monitoring. The testo 174/175/176 data loggers and testo 184 transport loggers ensure traceability of temperature and humidity (EN 12830 compliant, depending on model) in cold rooms, incubators, cryostorage or sensitive shipments (up to CO? and dew point depending on the application). The Testo 16x monitoring system links wired or wireless sensors with real-time alarms and user management. For routine work, Testo handheld instruments cover environmental checks (temperature, humidity, CO?, etc.), differential pressure in the cleanroom, air velocity in safety cabinets and fume cupboards, plus surface spot-checks with probe or IR. The digital ecosystem (apps and Smart Probes) streamlines data capture, documentation and secure sharing. On the quality side, the brand relies on ISO/IEC 17025 calibrations via Testo Industrial Services (DAkkS accreditation) and offers IQ/OQ, temperature mapping and validation services to safeguard your critical equipment. Known for sensor reliability, field robustness and audit readiness, Testo helps R&D, QC and maintenance teams underpin every decision with data, reduce risk and save time at inspections.
