Available data loggers
The following tables list the
HD35ED…
data logger models available. Other models, in addition to those listed, can be supplied upon
request for quantities.
To highlight the physical quantities measured by the data loggers, the ordering codes include some characters that identify the various
quantities, according to the following convention:
1
= Humidity
4b
= Atmospheric pressure (barometer)
4
= Differential pressure (
4r1
= range 1,
4r2
= range 2, etc.)
N
= Temperature with NTC10K sensor (
N/1
= 1 channel,
N/2
= 2 channels,
N/3
= 3 channels)
7P
= Temperature with Pt100/Pt1000 sensor (
7P/1
= 1 channel,
7P/2
= 2 channels,
7P/3
= 3 channels)
K
= Temperature with thermocouple sensor (
K/4
= 4 channels)
A
= Carbon monoxide (CO)
B
= Carbon dioxide (CO
2
) range 0…5,000 ppm,
B2
= Carbon dioxide range 0…10,000 ppm
I
= Illuminance low range (0...20,000 lux),
I2
= Illuminance high range (0...200,000 lux)
U
= UV irradiance (
U
=UVA,
UB
=UVB,
UC
=UVC)
R
= Solar radiation (pyranometer)
P
= Rainfall quantity
L
= Leaf wetness
S
= Soil volumetric water content
To indicate the fixed probe or the probe with cable, the following indications are used:
TC
= Probe with cable
TV
(or TVI) = Fixed vertical probe without cable
TCV
= Probe with cable + fixed vertical probe without cable
The models that measure temperature and humidity with combined probe with cable (models
…TC
) use the probes of the series
HP3517…
(with NTC 10K
W
@ 25 °C or Pt100 temperature sensor depending on the model).
The replacement of the probe HP3517… requires the
recalibration of the instrument in line with the new probe
.
