These industrial platinum resistance thermometers are working standards ideal for field and lab use. Suitable for use as working standards in dry blocks and liquid baths or as high accuracy probes for our range of true temperature indicators.

All the thermometers are metal sheathed and both less fragile and more affordable than the 909 range of true Standard Platinum Resistance Thermometers used in laboratories.

All the thermometers use handmade coil wound platinum sensing elements to give high accuracy and low drift. Isotech’s UKAS accredited lab can calibrate to the smallest of uncertainties.

Key features:

  • High stability reference probes
  • High stability Platinum coil element
  • Wide operating range
