The latest addition to
Seaward’s range of handheld
electrical installation testers
is the IRT1557 combined
insulation and continuity
tester. The lightweight
instrument is designed to
meet the measurement
requirements of the IEE 17th
Edition Wiring Regulations
and Part P certification.

Features include long life battery
operation and a large backlit LCD
that shows measurement readings in
both analogue and digital formats.

The tester has an integrated safety
probe that ensures the large backlit
analogue and digital LCD
test display remain in the
user’s line of sight while
circuit measurements are
taken.

Other features include
automatic discharge of
capacitive circuits, a lock
function to continuously
apply a test and automatic
audio warnings of high
voltage and low or high resistance.
