Zn-Thx11-S - Omron ZN-DPX21-S Series User Manual

* This product can operate up to approximately 2 hours with batteries only. However, the
battery life varies subject to measurement environment, conditions, and type or performance
of the batteries.

1.1.3 ZN-THX11-S

(1) High-precision Air Thermo Sensor
Air Thermo Sensor Head ZN-THS1-S allows for the accurate measurement of the
temperature and humidity with a temperature resolution of 0.1 °C (at 25 °C) and humidity
accuracy of ±2.5 %RH (25 °C, 10 to 85 %RH). The ZN-THS1-S contributes to the
improvement for better quality and management of temperature and humidity through
accurate measurement.
(2) Recording with SD memory card
The measurement data is accumulated in the internal memory and output as a CSV file to an
SD memory card by pressing the SET/REC/STOP key.
The internal memory can accumulate approximately 8,500 data, output them to an SD
memory card without stopping measurement and collect the data when required
In the SD memory card, the measured data is saved in the folder having a unique name to
identify the Air Thermo Logger. Therefore, even if two or more Air Thermo Loggers are
controlled, the data of each logger can be collected with one SD memory card while the data
in each logger is normally saved in each internal memory.
Approximately 17 million data items can be recorded (can be stored for 5 years with one Air
Thermo Logger with a measurement interval of 10 seconds).
(3) Graphical display software
The data output to the SD memory card can be displayed as graphs with PC software. The
graphs can be displayed by just specifying the SD memory card drive on the PC. The data
items of different periods can be connected, and the data items collected from one or more Air
Thermo Logger can be displayed side by side.
For details, refer to " Multi Data Viewer Light Software Manual".
(4) Alarm output
The main unit of the Air Thermo Logger has the alarm output terminals. The alarm will output
when the measured differential pressure exceeds upper or lower limit. This function allows you
to quickly handle problems by visualizing the limit of temperature and humidity.
(5) Battery drive
Other than supplying power from the outside, the product can be operated with batteries (two
AAA batteries). The battery drive can last approximately 1 year under the condition with a
measurement interval of 10 minutes, sleep mode and the use of rechargeable nickel metal
hydride batteries. The internal memory is always backed up so that it will not be deleted after
running out of batteries.
* The battery life varies according to measurement environment, conditions, and type or
performance of the batteries.
