Precise measurement technology for laboratories

Laboratories and Cleanrooms require precise measurement methods in order to be qualified according to their areas of application and quality requirements.Testo offers measurement technology and services which meet the strict requirements of a pharmaceutical environment.

Because according to the GMP guidelines (Good Manufacturing Practice), it is not only the uncompromising quality of the final product which must be guaranteed. During the process too, certain previously defined parameters must be adhered to. To do this, temperature monitoring in particular is essential in the different process steps. These are your measurement solutions for laboratories and cleanrooms:

  • Multifunction measuring instruments: combinable with different high-precision probes. Due to their high level of accuracy, they can even be used to test and calibrate stationary apparatus. 
  • Data loggers: ideal for the transport of sensitive substances and for monitoring process-relevant air conditioning parameters.
  • More portable measuring instruments: z.B. for pH measurement.

Whether you are producing in a validated or non-validated environment: Measuring instruments from Testo support you reliably in ensuring quality and adhering to standards.

Dust and watertight

The penetration/infrared thermometer testo 104-IR fulfils protection class IP 65. That means it is unaffected by dust and water jets:

  • Fast, non-contact measurement of the surface temperature thanks to 2-point laser measurement spot marker and 10:1 optics 
  • Exact measurement of core temperautre thanks to rigid penetration probe
  • Robust and practical: sturdy folding hinge, waterproof housing (IP 65)

Air temperature and humidity

Compliance with air conditioning standards

The thermohygrometer testo 608-H2 meets the requirements of DIN EN ISO 7726. So that your indoor climate in cleanrooms reliably meets the requirements: 

  • Measurement uncertainty of max. +/- 2 %RH
  • Continuous measurement and display of temperature and relative humidity
  • Calculation and display of the dew point

pH value measurement

Monitoring laboratory processes

The pH temperature measuring instrument testo 206 supports you reliably in Quality Assurance: 

  • Maintenance-free, leak-proof and insensitive thanks to gel electrolyte
  • Robust and watertight with protective case (IP 68)
  • Available in three designs: for liquids, for semi-solid to ductile materials or for flexible measurement thanks to connectible probes


Transport monitoring
