Overview
The PTC-125 cooler covers −90 to 125°C (−130 to 257°F), the low end of the PTC family’s −90 to 660°C span. The JOFRA PTC Series brings laboratory-grade temperature calibration into a portable package for pharmaceutical, oil and gas, and food-processing work. Active dual-zone temperature control maintains homogeneity in the well. Across five models the series covers −90 to 660°C (−130 to 1220°F), with accuracy up to ±0.06°C and stability of ±0.01°C. Fast heating — up to 350°C in seven minutes — reduces downtime. An easy-to-read color display and Plug and Play intelligent reference sensors simplify setup. JofraCal software supports data logging, thermocouple calibration, and reporting.
