Instrument Versions
LR-Cal FLUID 100-N Instrument Versions
The portable liquid bath (micro bath) LR-Cal FLUID 100-N is available in two versions:
Version LR-Cal FLUID 100-N
Standard version
Order-Code: FLUID100-N
Without measuring inputs
Version LR-Cal FLUID 100-N-2I
Version with 2 measuring inputs
Order-Code: FLUID100-N-2I

Both measuring inputs are suitable for resistance thermometer Pt 100 (2-, 3- or 4-wire) or Pt 1000, as well as for thermocouples (incl. cold junction compensation) types B, E, J, K, N, R, S and T.
The signal of connected probes can be displayed additionally in instruments display.

PC-Software LR-Cal AQ2sp incl. RS232-interface lead Temperatur sensor calibration: Automatic calibration routine for all type of temperature sensors with advanced features such reference sensor stabilization, time-calibration data are automatically populated and stored for printing report. This procedure can also be ran in manual mode to allow the operator to manually enter the data. This is particular useful when calibrating temperature device such as digital thermometer or analogue thermometers. Stress test: Simply set MAX and MIN value and the software will run an automatic stress test on single sensor or a batch. Advance thermostat calibration: Simply set the open and close temperature limits, type of thermostat, typ of test and the software will automatically run the test. |
