General description

The control and adjustment set (Order no.:
0554.0660) is used to check and adjust humidity
probes. The set consists of two special containers. Air
mixtures with defined relative humidities are produced
with the aid of different salt solutions.
As part of the accreditation as a DKD calibration
laboratory for the parameters "Relative humidity"
and "Dew point" the values for the relative humidity
for 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 control and
adjustment sets already delivered instead of the val-
ues specified up to now.
A control container with a defined humidity of 33%RH
is additionally available. It is used to
- bring the humidity probes to a defined initial state
before checking and adjusting.
- ensure that the humidity sensors or probes do not
dry out or become too humid during storage.
.
The humidity probe range from testo was convert-
ed to modified adjustment points in 1995.
The quality of the adjustment of older probes
does not change with the new control and
adjustment set. The values of ± 2%RH still
apply.
If new probes are adjusted using new control
containers, accuracies greater than ± 2%RH are
possible depending on how the points on pages 6
to 11 are adhered to. These values can also be
achieved with new probes using older control
containers.
