Portable Temperature Calibration Bath (Liquid Micro Bath)

Model LR-Cal FLUID 200-H

Temperature Range +20°C...+220°C


The LR-Cal FLUID 200-H is a portable stirred liquid bath (temperature calibrator). The instrument is suitable for calibrating temperature sensors and thermometers of all sizes, diameters and shapes, without the need of specifically drilled blocks. The calibration baths are perfect for checking and calibration of glass thermometers.

  • Large calibration volume 60 x 170 mm
  • Auto Ramp function, programmable
  • Auto Step function, programmable
  • Computer aided calibration via RS232 interface and optional PC software LR-Cal AQ2sp
  • Switch test functionality
  • Optional dry block and black body inserts available

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.
