The testo 175 H1 data logger measures, monitors and logs the temperature and relative
 humidity in buildings and closed rooms. The 175 H1 can monitor the indoor climate in 
buildings, storage facilities and archives and help create a comfortable 
climate in the workplace. 
 
The logger comes with an external humidity sensor (stub) for shorter reaction times 
and a lock to prevent it from being easily stolen or tampered with. 
 
In addition to the current temperature and humidity values, the logger can also log
 and display dew point values.  Other information including adjustable threshold 
values, breached thresholds and remaining battery power can also be read off the
 large, clear display. 
 
 
 
 Security and comfort on all levels  
The data logger testo 175 H1 ensures a high level of data security and reliable
 measurements based on leading-edge technology. It has a super-size memory 
that can save up to 1 million readings and an extended battery life of up to 3 years. 
This gives you the freedom to read out the data at longer intervals, even when the
 measuring cycles are shorter. The triple AAA batteries included in the scope of 
supply can be easily replaced by the user. 
 
 
 Programming and Analyzing the data Loggers  
 
Choose 1 of 3 software versions to program or read out the loggers or to analyze
 the measuring data you have obtained on your PC: 
 
-  Software ComSoft Basic– included – allows you to program your logger and analyze
 the data quickly and easily 
 
-  Software ComSoft Professional– optional – provides you with additional possibilities
 and a more detailed analysis of the temperature and humidity values 
 
-  Software ComSoft CFR 21 Part11– optional – ideal for the special demands of the 
pharmaceutical sector in compliance with 21 CFR Part 11 
 
You will need a USB cable (not included in scope of supply) to program your data logger. 
The data can be transferred to your PC either via USB cable or SD card. Both are
 optionally available as accessories which can be ordered along with your testo 175 H1.

With the temperature data loggers testo 184 T3, you monitor the transport of sensitive 
goods such as pharmaceuticals, foods or electronics, over an unlimited period. 
More info on applications (link to tab Applications)  At their destination, a glance at 
the display or the LEDs tells you whether the configured limit values have been 
adhered to. In order to obtain detailed information, it is sufficient to connect the logger
 to a PC – a PDF report is immediately generated with all relevant data. In order for
 you to be able to work even more efficiently and conveniently with the data loggers, 
all required files and information are stored directly and securely in the testo 184 T3: 
 Configuration file, acceptance test certificate 3.1 according to DIN ISO 10204, 
instruction manual and PDF report of your recorded data.  

The measurement value store of the temperature data logger testo 184 T3 has a 
capacity of 40000 measurement values. The measurement rate is freely selectable 
from 1 min to 24 h. The battery has a life of 500 days. The temperature data logger testo
 184 T3 is supplied by a standard battery which can be exchanged by the user. 
 testo 184 T3 is compliant with GxP, 21 CFR Part 11, HACCP and EN 12830. Testo is an
 ISO 9001-certified company, and ensures the adherence to the norms through internal 
audits as well as accredited external audits.  All advantages at a glance: 
1. Clear alarm indication  A glance at the the LEDs is enough to know whether limit 
values have been violated during transport.
2. Easiest operation testo 184 T3 is intuitively operated, and can be used without 
special training or previous knowledge: 
The "Start" button begins data recording. "Stop" ends it.     
3. Easiest configurationIn each testo 184 T3, a configuration file is stored, with which
 the configuration of the testo 184 T3 is childsplay – no download, no installation,
 no user interface and no additional costs.   
4. Convenient readoutA PDF report with the transport data is created immediately 
 on connection of the testo 184 T3 data logger to the USB interface of a computer. 
This is suitable for long-term archiving according to PDF/A standard.   
5. Mobile readout/printout on site All testo 184 T3 data loggers can be read out on site
 with an NFC-capable Android smartphone. Data transfer from the data logger to a 
 compatible Testo fast printer (option) also functions wirelessly via NFC.
6. IT-safe The testo 184 T3 data loggers work securely without software installation 
or download, so that IT problems are triggered neither by the firewall nor the virus scanner.
