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.
- Data recorder functions
- Programs and trend graphs
- PID temperature controller with colour touch screen 4.3 inches
- Adjustable speed magnetic stirrer (by potentiometer)
- High temperature stability up to ±0.01°C (±0.02°F)
- Lower temperature uniformity of ±0.05°C (±0.09°F)
- Two USP ports, one Ethernet port, for communications
- Temperature chamber with basket for temperature sensors to be calibratet
Insertion depth 190 mm (7.48 inches), diameter 60 mm (2.36 inches), volume 0.7 litres - Optional conversion to dry block temperature calibrator
