The portable dry well (metal block) temperature calibrator LR-Cal SOLAR is temperature source and reference instrument in one device, for checking and calibrating of all kind of temperature instruments, such as thermometer, RTDs, Thermocouples, Temperature switches, etc.
The ceramic equalizing block, whose large size suits the external dimensions, ensures a proper heat transmission as well as optimal stability and uniformity values. It's interchangeability makes it possible to test sensors of various lengths, with diameters ranging from 1 mm up to 26 mm.
The device is equipped with a counter-current forced air cooling system, which keeps the temperature in the upper part of the well low. This feature allows checking also of very short probes, without heating the connecting head or the handgrip.
The dry well temperature calibrator LR-Cal SOLAR is available in two versions:
Without measuring inputs
Version with 2 measuring inputs
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.
Extended scope of standard delivery:
Electr. cables, tools (plugs) for electr. connections
