Data loggers
HD35ED...
Wireless data logger that stores the measures in the internal memory and transmits the acquired data to the
base unit automatically at regular intervals or upon request. Optional LCD. Acoustic alarm with internal buzzer.
Powered by the internal not rechargeable battery. Supplied with: internal 3.6V not rechargeable lithium-thionyl
chloride (Li-SOCl
The radio frequency (868, 902-928 or 915.9-929.7 MHz) has to be specified when ordering.
The kit HD35.11K (pair of flanges, pin for padlock and padlock) for the fixed installation of the housing for indoor
use has to be ordered separately.
The external probes have to be ordered separately.

RADIO FREQUENCY:
E = 868 MHz radio frequency (Europe)
U = 902-928 MHz radio frequency (U.S.A. and Canada)
J = 915.9-929.7 MHz radio frequency (Japan)
PROBE TYPE:
Blank = internal sensors protected by grid
H = terminal header inputs
TC = probe with cable
TV (or TVI) = fixed vertical probe without cable
TCV = probe with cable + fixed vertical probe without cable
MEASURED QUANTITIES :
See table 3A for the combinations of quantities measured by the available data loggers. Other
models can be supplied upon request.
1 = humidity
4b = atmospheric pressure (Barometer)
4 = differential pressure: 4r1=range 1, 4r2=range 2, ... (*)
N = temperature NTC10K sensor:
N/1=1 channel, N/2=2 channels, N/3=3 channels
7P = temperature Pt100/Pt1000 sensor:
7P/1=1 channel, 7P/2=2 channels, 7P/3=3 channels
A = carbon monoxide (CO)
B = carbon dioxide (CO
)
2
I = illuminance (lux): I=low range, I2=high range
U = UV irradiance (U=UVA, UB=UVB, UC=UVC)
(*) For the differential pressure ranges available see table 3A.
TYPE OF LCD:
Blank = without LCD
L = with custom LCD
G = with graphic LCD
The type of LCD (custom or graphic) is not a choice, but enforced by the data logger model
(see table 2).
