Operating Range
The temperature of the sampled air may vary between -30 and 45 °C. The 5028i units
must be weather protected within the range of 4 °C to 50 °C.
An optional Complete Outdoor Enclosure provides complete weather protection.
Non-condensing; <95% RH inside 5028i
Sample Flow
Volumetric flow control system uses a calibrated subsonic precision orifice and the
measured ambient temperature and pressure to maintain constant volumetric flow rates.
Nominal Flow Rate: 16.67 L/min
Flow Precision ±2% of measured value
Flow Accuracy <5% of measured value
Data Storage
Internal data logging of user-specified variables; capacity of 190,000 records.
OFF – Heater is turned off in non condensing
environment
TEMP – fixed sample temperature
RH – Dynamic Heating of sample at set sample RH
