The values in brackets apply to special designs. These sensors are manufactured using

special sealing compounds. Moreover, they are equipped with connection heads made of

stainless steel and cable glands for the low-temperature range.

According to approval, these thermometers are suitable for the temperature classes

T6 ... T3. This applys for instruments without built-in transmitter and/or digital displays.

Thermometers with transmitters can be used for temperature classes T6 ... T4 and are

(for example T2) than marked is admissible. Make sure the maximal ambient temperature

for the safe use of the instrument is not exceeded.
