Digital temperature loggers - Information, resolution, accuracy

- Can the Loggers record temperatures between -90° C to 35° C ?
Yes

- Have the Loggers a part (transmitter) outside the cold room?
For an operating temperature between -40°C to + 85°C, it is easier to use data loggers with internal sensor. Then, the whole product is put inside the cold room. 
If the operating temperature is ouside those thresholds, the logger is then made of two parts, one part put inside the fridge (sensor) and the other one outside.

- What is the resolution of the measure?
@ 12-bit (0.1° C)

- What is the stability of long-term measure?
Drift smaller than the resolution for a period of 4 years of use.

- What is the measurement uncertainty of the Logger for a refrigerator 5° C +/-3° C? (Less than 0.75° C by the rule of quarter)
0.3°C

- What is the measurement uncertainty of the Logger to a freezer -20° C +/-2° C? (Less than 0.75° C by the rule of quarter)
0.3°C

- What is the measurement uncertainty of the Logger to an oven 37° C + / -3° C? (Less than 0.75° C by the rule of quarter)
0.3°C

- Are the Loggers “connected COFRAC” and do they are conform to the ISO 15189 requirements?
No, in standard offer, but proposed in option (“connected COFRAC” 1 point).
