Product Information
The LR-Cal LTC-DB-1100-44 metal dry block temperature calibrator serves as both a temperature source and reference device for testing and calibrating all types of temperature measuring instruments.
- Temperature range +200°C…+1100°C
- Homogeneous temperature distribution
- Easy operation with a colour touchscreen
- Ramp function + thermostat tests
- Computer-controlled calibrations via USB interface and optional LR-Cal Aq2Sp2 software for MS Windows® PCs
- Numerous block inserts with different bores are available for different test objects
- Option: Block insert with “black body radiator” for calibrating infrared thermometers
Less thermal stress for your test specimens
The LR-Cal LTC-DB-1100-44 metal dry block temperature calibrator is equipped with a counterflow forced ventilation system that keeps the temperature in the upper part of the calibrator very low. This solution enables keeping the connection head or housing of the device under test very close to room temperature.
It also ensures a high level of safety for the operator, as the temperature of the grille on the top of the housing remains very low.
The figure shows a thermocouple as a test object in an LR-Cal LTC-DB-1100-44 at 1,000°C. The temperature of the test object’s connection head, measured with an optical pyrometer, is only 37.7°C, which is very close to room temperature. This test confirms the excellent insulation of this calibrator
