Data logger models in indoor-use housing
In order to highlight the physical quantities measured by data loggers, order codes include
some identification characters for 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/2 = two channels, N/3 = three channels)
7P = Temperature with Pt100/Pt1000 sensor ( 7P/3 = three channels)
A = Carbon monoxide (CO)
B = Carbon dioxide (CO
2
)
I = Illuminance (lux)
U = UVA irradiance
TC = Probe with cable
TV = Fixed vertical temperature and/or R.H. probe without cable, with high accuracy R.H.
sensor
TVI = Fixed vertical temperature and R.H. probe without cable
TCV = Illuminance/irradiance probe with cable and fixed vertical temperature and R.H. probe
without cable, with high accuracy R.H. sensor.
Models measuring temperature and humidity with a combined probe with cable ( …TC models) use
the probes of the HP3517… series with high accuracy humidity sensor and NTC 10K Ω @
25 °C or Pt100 temperature sensor according to the model. Replacement of the HP3517…
probe requires recalibration of the instrument in line with the new probe .
Models with M12 connectors provided with inputs for the measurement of temperature only, use
temperature probes of the
TP35… series with NTC 10K Ω @ 25 °C or Pt100/Pt1000 sensor.
In models with 2 or 3 M12 connectors, the input number is indicated above the connector.
In models for the measurement of the atmospheric pressure, the sensor is inside the instru-
ment.
In models for the measurement of the differential pressure, please pay attention to the polarity
indicated next to connections.

Model Measuring range
HD35ED...4r1… -2.5…+2.5 hPa (mbar)
HD35ED...4r2… -10…+10 hPa (mbar)
HD35ED...4r3… -100…+100 hPa (mbar)
HD35ED...4r4… -2000…+2000 hPa (= 2 bar)
For the probes connection mode and the position of the integrated sensors in the various mod-
els, refer to the figures indicated in the last column of the following table.
