Gemini 550 LRI is a portable calibration dry block for temperature thermometers from 35°C to 550°C. It has a high capacity to allowing a large number of probes to be calibrated together. They are also suitable to accept large diameter probes with the block volume of 65 x 160 mm.

Whilst the large block takes longer to heat and cool than other models, it can calibrate thermocouples, resistance thermometers, thermostats and sensors that are too large for the smaller blocks. 

Gemini 550 LRI comes with a removable block of 8x 8 mm holes.

Gemini 550 LRI is available in two models, the BASIC (B) and the SITE (S).

The B model includes a sophisticated temperature controller with a dual display for set temperature and dry block temperature.

The S model additionally includes an in-built temperature digital indicator to which an external temperature sensor can be connected, giving greater accuracy eliminating temperature gradient and loading errors.

For laboratory accuracy, Gemini 550 LRI can be used with high-end temperature indicator.
