TEMPERATURE RANGES
Scale, measuring range, limit of error per EN 13 190 class 1
(1) The measuring range is indicated on dial by two triangular marks. Within this range the stated limit of error is valid according to EN 13190
STEM LENGTHS TABLE
Minimum stem length mm
NOTE::
For shorter length ask our technical dept.
For compound range, like –20 to 60°C, the stem length minimum is the same as 0/80 °C, by considering the total spam.
