T955 2-channel laboratory instrument
Order Number: 
The universally applicable process-controlled hand-held instruments, Series T900, are ideal for measuring operations in which high accuracy counts or the possibility of online documentation is demanded. Product features -RS232 interface galvanically isolated -Optional SmartGraph Windows Software for graphic and tabular documentation -High accurate analog output (0-1 Volt) -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 theri 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.

Areas of application

  • For taking measurements for quality assurance under ISO 9000
  • As a reference instrument for checking production
  • For taking comparison measurements in service and repair
  • For registration of humidity and temperature in air conditioning and environmental engineering
  • Long-period monitoring of temperature and/or relative humidity with online documentation
