* Using the logger within the extended temperature operating range requires the use of the CR2450HT battery.
** The steel tube may be used from -40 to +100°C only, while the steel tube of the YL-T10E can be used with temperatures of up to +130°C. The given limitations of use for the external probes may change due to the cable used for connection. PVC cable type V can be used from -20 to +80°C, Teflon cable type G can be used from -70 to +250°C.
