Hart Scientific 1521 Overview
The 1521 and 1522 read both Pt-25 and Pt-100 RTDs as well as thermistors.Of course, the 1521 and 1522 let you match the exact resistance-versus-temperature characteristics of an individually calibrated probe. Hart’s Handheld Thermometers read ITS-90, Callendar-Van Dusen, or Steinhart-Hart coefficients for maximum system accuracy.
