P755L

High precision data logger for temperature (±0,03), relative humidity, dew point, air flow with memory for 6.000 measurements. The instrument is designed for application of the quality assurance, e.g. testing climatic chambers, calibration thermostats, oven...or thermoelectrical processes. For the battery-powered instrument we provide a separate power supply as an option. The measuring interval is adjustable between 1 second and 30 minutes. By using our precision Pt100-probes with sensor calibration code you will reach high system accuracy. The P755-LOG measuring system is the perfect standard to test subordinated instruments or systems. For traceability we recommend to order those instruments with a calibration certificate.
