Spec-Cal® Eclipse II - Multi Function Process Calibrator

Haven’s Multi Function Process Calibrator, the Spec-Cal® Eclipse II, measures and simulates 12 different thermocouple types and 7 different RTD types to any of four selectable international standards (BS, JIS, DIN & ANSI).

The Spec-Cal Eclipse II Multi Function Process Calibrator can also simultaneously measure and generate mV, mA, volts or ohms.
** Please see note below 

The hand-held, battery powered Spec-Cal® Eclipse II Multi Function Process Calibrator is protected by a tough, EMC shielded, aluminium case with a durable, splash-proof, polycarbonate keypad which has excellent tactile and audible feedback, a high contrast super twist LCD display and switchable backlight. With the option of operating in 5 different selectable languages, the Spec-Cal Eclipse II Multi Function Process Calibrator is also available as a panel mounted version which is mains powered, with a permanently backlit display. This is ideal for inclusion into a Calibration Test Bench.
