Loop calibrator with easy-to-use interface

Supplier News

FLUKE Corporation has introduced the Fluke 707 loop calibrator, the newest member of its family of portable, process calibration tools.

The Fluke 707 features a new ergonomic design that combines the best of knob-based and button-based loop calibrators in one device.

Compact and easy to hold, technicians can easily operate the tool with just one hand. At just six inches (152mm) in length and weighing a mere 12 ounces (340grams), the Fluke 707 is a rugged, reliable calibration tool that can source, measure, and simulate loop current.

The Fluke 707 is two-and-a-half times more accurate than any other loop calibrator in its class, with an 0.015 per cent accuracy and 1μA resolution in any current mode.

A 24V internal loop supply enables the user to power and read a transmitter at the same time using a single instrument.

The 707 provides simultaneous milliampere and percentage of span readouts making it suitable for process instrument technicians in the primary metals, refining, chemicals, pharmaceuticals, and power generation industries.

Selectable slow ramp, fast ramp, and step functions provide the user with test signals needed for valve slewing and loop functional tests, allowing a single technician to troubleshoot the entire loop.

The Span Check function instantly selects zero and 100 per cent of span outputs. A 25 per cent button conducts quick linearity checks at 25 per cent steps, and the innovative new knob style allows fine and coarse adjust vernier with 1μA and 100μA resolution. The calibrator can measure loop power supply voltages up to 28V dc.

The instrument uses a single nine-volt battery that is easy to replace through the quick-change door, without compromising the calibration of the instrument.

The Fluke 707 is backed by a three-year warranty. It comes complete with test leads, test clips, instruction sheets in 14 languages, and a protective C-10 holster that allows hanging from pipes, rails and joists. Fluke Australia 02 8850 3333.
