Temperature range -24°C...+140°C, Accuracy ±0.25°C, Stability ±0.05°C
Block diameter: 1 x 19 mm (in aluminium), Insertion depth: 104 mm


This compact and innovative dry block temperature calibrator is especially designed for field applications, robust and able to maintain high accuracy and stability in severe conditions such as offshore rigs and on board of vessels. The self contained unit is very compact, portable and light weight. The innovative forced air ventilation of model LR-Cal PYROS 140-1L greatly reduce the cooling time and prevents the sensors under test from being exposed to excessive heating.
