Description of the instrument
Use
The testo 160 TH, THE, THL, THG, IAQ and E data loggers are handy measuring instruments for measuring temperature, humidity, CO2 concentration, illuminance and UV.
The external probes S-TH, S-LuxUV and S-Lux are only approved in conjunction with the testo 160 THE and testo 160 E data loggers.
You can find further information about proper use in the instruction manual for the testo 160 data loggers or online beneath the login of the respective testo application: www.testo.com/login

Commissioning
Inserting into / removing from the wall bracket
- Insert the unlocking tool into the unlocking opening.

- Push back the locking pin using the unlocking tool.
- Pull the data logger up and out of the wall bracket.

Starting up the data logger
The data loggers must only be mounted vertically. Here, the connections must point downwards. In the case of data loggers with a display, you need to pay attention to the reading direction. Otherwise, the measuring accuracy might be diminished.
- Open battery compartment cover.

- Remove battery safety strip.
- Close the battery compartment.
The IAQ data logger has a higher energy requirement. This reduces the minimum measuring cycle to 5 minutes when battery-operated. Operation via mains unit is therefore recommended. An appropriate USB cable can also be purchased as an accessory.
Only for testo 160 E and testo 160 THE:
The external probes must be connected before logging into the Cloud for the first time. If an additional probe is to be connected at a later stage, the data logger must first be logged out of the Cloud. The external probe can then be connected and the data logger logged in again.
Logging into the Testo Cloud
You need an account for the Testo Cloud. If you have not yet set this up, please sign up at https://www.museum.saveris.net.
For your new testo 160 WIFI data logger to be able to connect to your account in the Testo Cloud, it requires the three following pieces of information at minimum:
- The ID of your account in the Cloud. You will find this in your account under the menu item Configuration – Account ID.
- The network name of your WIFI (SSID), which the WIFI data logger will use to connect to the internet.
- The password for this network.
Storage of this information on the WIFI data logger is called “Configuring the WIFI data logger”. Four different options are available for this process.
Configuration via the Setup Assistant
The Setup assistant in the web interface of the Testo Cloud is provided to assist you when you take your first steps with commissioning the testo 160. It can help you with logging in WIFI data loggers.
To be able to carry out the configuration, you need to be logged into the web interface at https://www.museum.saveris.net.
- Click on the
symbol above the menu bar.
The Setup Assistant launches and assists you with the configuration. Follow the instructions there.

Calibration
testo 160 WIFI data loggers come with a factory calibration protocol as standard. For museums, we recommend having an annual test carried out by Testo Customer Service. Moreover, there is an option of having ISO certificates created for the WIFI data loggers. These can be implemented by Testo Industrial Services (TIS).
Technical data
Measurement-specific data
The humidity sensor attains the highest degree of accuracy in temperatures between + 5 °C and + 60 °C and 20% to 80% RH. If the instrument is exposed to higher humidity for a long period of time, this can falsify the readings by up to 3% RH. After 48 hours at 50% RH ± 10 % and +20 °C ± 5 °C, the sensor regenerates by itself.
CAUTION
Damage to the humidity probe
- The probe must never be exposed to a humidity level of 100 % RH for longer than 3 days

Technical data for a secure wireless LAN
Ports
The testo 160 WIFI data loggers use the MQTT protocol, which communicates via port TCP 1883 and 8883.
These UDP port approvals are also required:
- Port 53 (DNS name resolution)
- Port 123 (NTP time synchronisation)
All ports only have to be able to communicate externally to the Cloud. No bi-directional port approvals are necessary.
During the initial configuration, it is possible to select whether DHCP or Static IP is used (select Expert mode for the corresponding information). (Not possible in the Setup assistant.)
testo 160 application
The testo 160 application is accessible via a normal, up-to-date browser (www). The standard TCP ports http (80) and https (443) are used.
