Replace your Sato SK-250WP with the SK-270WP-K for straightforward contact temperature measurement. Choose the probe to suit your sample, required insertion depth and operating temperature.
Replacing an SK-250WP
When requesting a replacement, provide the model number of your existing thermometer and probe. The SK-270WP-K uses dedicated S270WP series probes; Sato confirms that SK-250WPII probes are not interchangeable with this series. Specify a complete thermometer and probe set when upgrading.
Everyday measurement functions
