The Digital Thermometer Model 869C, does it only come as a calibrated tool upon initial purchase. Meaning are their options for either a calibrated (869C) or non-calibrated (869) model.

Asked by: Mike Addison
If you are looking for a NIST traceble calibration add CAL-3 when ordering (869C-Cal-3). Also please note that due to regulation change this product is not CE at this moment. Please contact our Tech Support if you have any further questions. Thank you.
