The data logger modules

testo Saveris 1 data loggers

Every data logger can be flexibly combined with the three communication modules (WLAN, LAN, testo UltraRange)

  • testo 150 TUC4: Four connections for digital probes via Testo Universal Connector
  • testo 150 TC4: Four connections for thermocouples for applications in extreme conditions
  • testo 150 DIN2: Two connections for standard probes via miniDIN for using the comprehensive Testo probe range
  • testo 150 T1: Internal NTC temperature sensor for monitoring temperature

The communication modules

testo Saveris 1 WLAN

The communication modules allow the use of different communication technologies with the testo 150 data logger modules:

  • Existing infrastructure (WLAN or LAN/Ethernet)
  • testo UltraRange long-range radio technology

Even after commissioning, communication and data logger modules can be flexibly connected with each other and exchanged.

The Base station

testo Saveris 1 Base station
  • The heart of the environmental monitoring system testo Saveris 1
  • testo UltraRange functionality via additional communication module
  • Management and analysis of the measurement values of up to 3,000 channels
  • GxP-compliant alarms in cases of limit value violations or critical system events via integrated LED or connected alarm provider (via relay)
  • Integrated emergency battery for highest data security in case of power cut or other system malfunctions

The Gateway and the testo UltraRange technology

  • For the smooth integration of other measurement parameters (e.g. differential pressure)
  • 4 – 20 mA connection via the testo 150 TUC4 data logger module
  • Standardised interface for easy integration

The digital and analog probes

testo Saveris Pharma probes

Digital and analog temperature and humidity probes for high-precision measurements of relevant parameters in a regulated environment.

  • Measuring range from -200 to +1300 °C for almost any possible scenario
  • Probe exchange in seconds without data gaps in the documentation
  • Easy handling and installation
  • Efficient system monitoring with digital door contacts

Transmitter for humidity and differential pressure

High-precision measurement technology, intuitive software and comprehensive services will help you to do your job quickly, efficiently and in compliance with current regulations.

Smooth processes and convenient documentation

In medical, biotechnical, chemical and pharmaceutical laboratories and cleanrooms, important climatic parameters have to be monitored. This is the only way to protect sensitive samples and maintain a high quality standard. Temperature in particular is a critical parameter that must be monitored. Humidity and pressure must also be included in standard-compliant environmental monitoring.
testo Saveris 1 Laboratory

Safe production of sensitive pharmaceuticals

If temperature-sensitive goods such as pharmaceuticals, foodstuffs or lithium batteries are produced and stored under the wrong climatic conditions, the quality and stability of the products can suffer. In most cases, internationally valid minimum standards stipulate that the relevant areas are qualified and the environmental conditions are monitored and documented in a manipulation-proof way.

More security in storage and transport

In the general storage and logistics of goods of any kind, minimum standards are often required when it comes to temperature monitoring. This applies to the pharmaceutical industry and medical technology as well as to the food sector or logistics and industrial companies in general. The reason: Monitoring is the only way to ensure that the quality and safety of products are not jeopardized.

Certainty for hospitals and pharmacies

In healthcare, environmental measurement solutions are used in many different areas to ensure patient safety and to reduce the risk of product losses and compliance violations. Whether in hospital operating theatres and treatment rooms to monitor medications, in a blood and tissue bank to protect samples, or in an in-house pharmacy where sensitive medications are manufactured and stored.
