Portable Temperature Micro Calibration Bath

Model LR-Cal LTC 200-F

Temperature range +30°C...+225°C

The LR-Cal LTC 200-F is a portable stirred liquid bath (temperature calibrator, micro bath). The instrument is suitable for calibrating temperature sensors and thermometers of all sizes, diameters and shapes, without the need of specifically drilled metal blocks. This advanced micro bath is perfect for checking and calibration of glass thermometers, as well as all other kind of temperature measuring instruments.
