Monitoring and documentation of laboratory conditions

The ambient conditions for research projects must frequently be documented in laboratories to check external influencing factors. In addition to recording temperature and humidity, this also includes checking the absolute pressure. There are major requirements in terms of reliability, along with tamper-proofing and data security of the recording instrument, as incorrect documentation could invalidate the whole research result. There are only a few instruments which can log all three measurement parameters at the same time and also offer the required amount of data security.
