Testo, 0572 1767, 176 P1 5-Channel Pressure/Temperature/Humidity Data Logger with External Sensor ConnectionsThe testo 176 P1 pressure, temperature, and humidity measurement logger has a large display that makes it easy to read. The 176 P1 is an ideal pressure, temperature, and RH data logger for the highly accurate and secure documentation of conditions in a laboratory, enviro chamber, clean room, or hospital control area. Creation of Excel Spreadsheets, PDFs, and data analysis are all easily achieved with the free, downloadable ComSoft software.IncludesTesto 176 P1 pressure, temperature, and humidity highly accurate measurement loggerBatteriesCertificate of conformityFeaturesPressure, temperature, and humidity measurementsInternal pressure and external temperature and humidity probes for quick, highly accurate measurementsLarge, easy to read, backlit displayLarge data memory capable of storing 2,000,000 measurementsThe testo 176 P1 pressure, temperature, and RH data logger is an ideal, highly accurate data logger for the monitoring of pressures, temperatures, and humidity.Internal pressure and external NTC sensor connectionsData transfer possible using the USB port, or SD card (Optional)Easy to read large display that shows current readingIP54 protection classCapable of CFR 21 Part 11 CompliancyFree data logger software available for downloadData is secured within the logger, and can be password protected using ComSoftMonitoring and documentation of laboratory conditionsThe 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.
