Accuracy of PT104 and SE017

Postby Guest » Mon Jul 06, 2009 11:21 pm


I am looking at this combination, PT104 and SE017. Is the accuracy measured as simply the PT104 is 0.01C and the probe is 0.15C. So the probe dominates and 0.15C is the best I can achieve?

I am looking to record ambient room temperature and 3 points with in a refrigerated cabinet that operates from 4-30C. I am observing the gradient across the cabinet.

Are there more accurate probes that can get closer to the tolerance of the PT104? PT1000? I currently have a unit with a 0.2C tolerance. I am looking for something in the 0.0# C range.

Hi Andrew

You need to add the sensor error to the PT-104 error. See the following page for our range of PT100 sensors:


For this kind of accuracy, you may want to contact a sensor specialist such as Alphatemp Technology:
