Product Description:

multi-function instrument for temperature-humidity-airflow-pressure

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. 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.

Product features

  • USB interface
  • Optional DE-Graph Windows Software for graphic and tabular documentation
  • High measuring accuracy
  • Integrated calibration function for simple compensation of sensor tolerances
  • Physical 1-point, 2-point or 3-point calibration function
  • Measuring channels are freely assignable
  • Recording maximum, minimum, hold and average values
  • Integrated sensor holder for one hand operation
  • Mains operation possible
  • Simultaneous display of two measured values
  • Differential temperature display

The two multi-function instruments are outstanding for their high accuracy of ±0,03°C. You can optional plug in Pt100 or thermocouple (type J, K, L, N, R, S, T), as well as probes for humidity and flow. The high precision makes them eminently suitable as reference instruments for testing subordinate measuring instruments in quality assurance laboratories or for checking temperature- critical processes. These instruments are frequently provided with a DKD calibration certificate.
