ERWEKA TBH 425
Hardness Tester for automatic measurement of
up to 10 samples. Via the numeric membrane
keypad with alpha-numeric sub function the
nominal hardness in combination with 2 individ-
ual plus/minus tolerances (T2 = pass/fail crite-
ria) and remarks may be stored for up to 20
different products and recalled for testing. In-
formation such as product name and remarks
can be entered similar to writing a message on
a mobile phone. Stored product data can be
transmitted via SD card or USB stick to other
devices of the TBH 325/425 family. Calibration
is completely menu guided and may be per-
formed by either weight stones or the electronic
ERWEKA AutoCal System. Via a standard USB
printer interface a printer can be connected to
receive hardcopy documentation.
The serial LAN/USB interface allows connecting
a computer with the optional MC.net software
for external control. In combination with this, the
TBH 425 series is 100% 21 CFR 11 compliant.

This function allows verifying that the sample
was perfectly aligned before testing hardness.
Additional features:
 Measuring range for diameter: up to 28.00
mm
 Accuracy 1 N; 0.03 mm
 Values in mm or inch
