All
display with menu indication makes the operation easy and convenient.
English
l
Alternative white backlight display and USB plug facilitate the opeation in darkness
and communication with PC for data exchange and configuration.
l
The
is matchable with 7 striking fittings, capable of identifying the striking
type automatically, and requires no further calibration after replacement.
main unit
l
The unit can store up to 500 groups of date(
times 32~1), in which each group
contains information of single value, average value, measuring date,
direction,
times, material and hardness unit.

l
When using D/DC type
for steel material hardness testing,
the reading can be displayed directly without consultation of the table.

l
Equipped with PC program, this software supports transmission of the measuring
results, storage management, statistical analyzing, print and massive parameters
setting to ensure higher quality and management.
l
Professional and nice outline, smart, portable and reliable performace makes the unit
operatable in rough environment, and immune from vibration, striking and
elecmagnetic interference.
