AMETEK Jofra RTC-156 A Temperature Calibrator, -30 to 155°C
AMETEK Jofra RTC-156 A Temperature Calibrator, -30 to 155°C
AMETEK Jofra RTC-156 A Temperature Calibrator
Overview
The RTC-156 A is the base model of AMETEK's RTC reference temperature calibrator line. Its active dual-zone technology independently controls two heating zones so the well bottom dissipates heat while the upper zone compensates for losses at the open top, giving near-bath homogeneity in the 30 × 150 mm insert. Mains variance immunity (MVI) keeps the block stable even in plants where large loads cycle on and off.
Set temperature resolution is 0.001°, up to 20 auto-step routines and 10 instrument setups can be stored, and the stability indicator with count-down timer tells the user when to read the sensors. The lightweight design (about 10.5 kg) and all-in-one carrying case make it easy to move between bench and site.
