The Ametek Jofra ETC Series includes three portable temperature calibrators designed for field testing of temperature sensors where time is critical and highest accuracy is not required. Their compact size fits in a toolbox, ideal for sensors in difficult-to-access locations.

ETC-125A Dry Block (-10 to 125°C): Heats and cools for applications like air conditioning and cold counters. Interchangeable insertion tubes accommodate various sensor diameters. Heating time 11 minutes to 100°C, stability ±0.05°C.

ETC-400A Dry Block (28 to 400°C): Optimized for speed with holes drilled directly into the block. Heats to 400°C in 5 minutes, stability ±0.15°C.

ETC-400R Infrared (28 to 400°C): Features 36 mm blackbody target with emissivity 0.96 for IR thermometer calibration. External reference sensor well (3 mm) for higher accuracy. Stability ±0.3°C.

All models feature One-Key-One-Function interface, stability indicator with 3-minute countdown, auto-stepping up to 20 steps, and RS-232 with JOFRACAL software for documentation. ETC-400R includes IR-LAB software for emission factor calculations. Rugged stainless steel and rubber construction.
