Control And Calibration Options - TESTO 0636.9835 Application Information

Control and calibration options

The control and calibration set (Order no.: 0554.0660)
is used to control and calibrate humidity probes. The
set consists of two special containers.
With the aid of different saline solutions, air mixtures
with defined relative humidities are produced (for
additional information see the Instruction Manual
"Control and calibration set for humidity sensors").
As part of the accreditation as a calibration laboratory
for the parameters "Relative humidity" and
"Dew point" the values for the relative humidity over
the saturated lithium chloride (LiCl) and sodium
chloride (NaCl) solutions were newly specified at testo.
LiCl 11.3%RH, NaCl 75.3%RH
at rated temperature +25 °C
These improved values also apply to all of the control
and calibration sets already delivered. Ignore the
values specified up to now.
