Are your samples safe when you're away?

temperature monitoring and alerts for LIFE SCIENCES

  • Prevents loss of your irreplaceable research, specimens, and samples
  • Alerts notify appropriate researchers and facilities staff when temperatures reach critical limits
  • Alert method (email, text, and/or phone call) and active time of day can be tailored per recipient


  • Easy to install—DIY simplicity, "plug-and-play" installation
  • Easy to set up—sensors start monitoring as soon as they are powered up, just name sensors and set up alerts
  • Easy to operate—web-based alert set up, reporting, and graphs


  • All sensor data is encrypted during transmission to Coris servers and is permanently logged
  • No local sensor control unit or server that can be hacked or require a "hole" in your firewall for remote access
  • All sensor logs are maintained on secure servers in secure data centers in the cloud—cannot be altered by users

(-250°C to +250°C)

Coris' encrypted wireless mesh network enables your sensor modules to communicate with one another to reach a Gateway.  This allows one Gateway to support 35 Coris devices.

Sensors that monitor temperature, humidity, and/or contact closure are installed in your freezers or incubators.

The sensors are connected to a Coris ETS or MSM (depending on sensor type).

Once your Coris Gateway is connected to a router with an Ethernet cable, it automatically connects to Coris servers on the Internet.

Secure Coris servers record all data received from sensors—accessible anytime, anywhere.

a few features

alerts customized to your needs

A crucial feature of Coris technology is its ability to notify the appropriate people when there are problems that need attention. The Coris servers send out messages to any number of people once specified conditions (temperatures, humidity levels) are exceeded for a user-defined delay interval.




more options


For all types of freezers and liquid nitrogen tanks, rising temperatures mean that frozen specimens are at risk. Even if temperatures stay below -50°C, degradation of certain samples can occur. Not only facilities staff, but individual researchers may want to be notified if their research specimens are in jeopardy so that they can move them to another freezer. A typical temperature alert is below.


Besides knowing about individual freezer problems, your facilities staff also needs to know if communications with sensors have been lost, as it indicates a network or communications problem that could affect multiple cold storage devices.


For incubators, it is important to monitor both temperature and humidity to ensure a proper growing environment. When readings are outside ideal conditions, facilities staff and researchers need to be notified so that repairs or adjustments can be made.


Alerts can also be set up to monitor other Coris controller or sensor status, or even external factors (weather, price of electricity, demand response signals from utility, etc.).


To maximize the effectiveness of alert messages, they can be sent out in multiple formats: emails, text messages, phone calls, and via pager networks. Critical alerts can be escalated until someone takes responsibility for the alert, eliminating the tragedy where several people are notified of a problem, but all figure someone else will take care of it.

sensor names and organization

Each sensor has  a unique ID number, but should be given a meaningful name to help identify it. A description can also be give to further identify the sensor (e.g. “LN2 tank 43 in Boston” and “Dr. Smith virus lab”), and then the sensors can be organized within folders.


Similar to creating file folders on a computer, Coris sensors can be organized into folders by any category – lab names, floor numbers, department names, building names, city, etc.  There is no limit to the number of folders and subfolders you can use—allowing sophisticated organization of large numbers of sensors.

sub-accounts allow you to delegate controls and access

For institutions with large numbers of sensors, access to sensor data can be limited based by assigning sub-accounts. These accounts exist within an overarching user account, but only have access to those folders and devices that the main user deems appropriate.

“After the scare we had when a freezer failed on a weekend, we are glad we purchased the Coris temperature monitoring systems to warn us of any future problems.”

Coris in the lab

Power Outage Protection








Hurricane Sandy knocked out power in a lab for more than eight days, and innumerable research samples were ruined when ultra low freezers shut down.  Back-up generators were since installed, and Coris ETS modules were installed to provide temperature monitoring and permanent logging as well as multi-method alerting capacity so that all appropriate lab personnel (individual researchers, principal investigator, facility management staff) will be notified if any of the freezers has a problem that results in a change of temperature.  Further, these alerts automatically escalate until someone takes responsibility for dealing with the problem.  The goal—no more lost research samples.

Federal Research Lab








A small, remote federal research lab with a few cryo freezers has been planning an upgrade to their lab, with all personnel participating in the planning.  One of the researchers realized she left her planning notebook in the lab over the weekend; when she went to the lab to pick it up, she realized the temperature warning alarm on one of the freezers was sounding.  She put the key samples that were at risk into an ice chest and added liquid nitrogen to keep everything frozen—saving the day.  On Monday morning, the principal investigator researched temperature monitoring and alerting systems, received pricing and capability information from the most promising vendors, and then ordered Coris Extreme Temperature Sensors to monitor the freezers.

Medical School








A medical school consolidated most of their ultra low temperature freezers into a “freezer farm” with a large back-up generator to ensure all the freezers will never lose power.  Each freezer temperature alarm was tied into the building’s management system to detect freezer problems.  Small labs in other buildings on campus implemented Coris ETS systems to provide the freezer “alarm” feature, and also have detailed temperature logs, which the central alarm system does not have.


How do I install Coris temp sensors?

Place the sensor in the device to be monitored, plug the other end into a local Coris MSM or ETS, and plug its power adapter into a wall outlet. The MSM or ETS will automatically start sending readings to the Coris servers.

Can I monitor two ultra cold freezers with one ETS?

Yes, each ETS has two independent thermocouple ports. While the standard Coris thermocouple is 72 inches long, custom sizes up to 300 inches are available—so the freezers don't need to be right next to one another.

Can I monitor liquid phase LN2?

Yes, there is a specially-designed thermocouple with a stainless steel shaft that will withstand long-term exposure to liquid nitrogen (-196°C). Most LN2 dewars have an access port for an external temperature probe. Standard Coris Type T thermocouples will monitor temperatures from -250°C to +250°C.

Is there a limit to the number of units I can monitor?

No, you can keep adding Coris ETS modules to an account to monitor any number of units. Each ETS module has two independent thermocouple ports, up to 35 ETS modules can share one Coris Gateway module, and there is no limit to the number of Gateway modules that can be active at any installation site.

What do I need to get started?

You will need an Internet connection, a Coris Extreme Temperature Sensor  (ETS) module, a Coris thermocouple, a Coris Gateway, module, and wall outlets (for the power adapters for the ETS and Gateway). Each ETS can monitor two thermocouple sensors, and each Gateway can support up to 35 ETS modules!
