Frequently Asked Questions

CORIS Remote Temperature Monitoring System

CORIS provides a complete system for remotely monitoring lab equipment and sending alerts when conditions are outside of acceptable thresholds.

Remote Monitoring

What components are required for monitoring temperature?

  1. CORIS temperature probe is a very thin wire that is placed inside the device to be monitored (LN2 tank, -80, -20, +4, etc.). It measures the temperature inside the device.
  2. CORIS Extreme Temperature Sensor (ETS) module wirelessly transmits temperature readings from its attached probes. Each ETS can monitor two separate freezers, refrigerators or LN2 tanks.
  3. CORIS Gateway module receives wireless transmissions from the ETS module(s) and forwards the readings to the CORIS cloud-based servers for analysis and storage.
  4. Your phone or computer is necessary to access temperature readings and receive alerts.

What types of cold storage devices can be monitored?

CORIS monitors temperatures in all types of freezers and refrigerators: liquid nitrogen (LN2) tanks and dewars (-196), -86C, -40C and -20C freezers, and +4 refrigerators.

What temperature range can be monitored?

The CORIS Extreme Temperature Sensor (ETS) probes cover a range of -250°C to +250°C. Higher temperature monitoring is available by special order.

What else can be monitored besides temperature?

The CORIS system can monitor humidity, CO2, water/flood detectors, door open/closed, motion/occupancy, and external alarm circuits.

Is there a limit to the number of cold storage devices that can be monitored?

There is no limit to the number of cold storage devices that can be monitored. Hundreds of CORIS ETS modules and temperature probes can share one CORIS Gateway, and there is no limit to the number of CORIS Gateways that can be active for any customer, in any number of locations.

Once we have a system in place, can we expand it?

Additional CORIS Extreme Temperature Sensor (ETS) modules can be added at any time to monitor any number of devices, so you can start with a single device and grow to thousands.

How frequently are temperatures recorded and sent to the cloud?

The ETS module continuously records the temperature in each freezer and sends the temperature readings to the CORIS Gateway every two minutes. The Gateway sends the readings to the CORIS cloud-based servers. These temperature readings are immediately available to view or graph, and are permanently stored in the CORIS servers.

What happens if the Internet or electricity goes down?

The CORIS system will alert you via text, email, or phone call when communication with the temperature sensor is lost, so you will know there is likely a local power or Internet failure.

Is battery back-up available?

Yes, the optional ETS internal battery pack allows the ETS to continue to operate up to one month if its normal power supply is interrupted. The CORIS Gateway and its Internet connection must remain working for ETS temperature readings to be sent to the CORIS servers.

Is there a warranty on CORIS products and services?

Yes, CORIS offers a complete warranty with immediate replacement of all failed hardware components for the term of the license agreement or three years, whichever is longer.

Is the CORIS system compliant with industry regulations (HIPAA, CAP, CLIA, CFR 21 Part 11)?

Yes, the CORIS system is compliant with HIPPA, CAP, CLIA, and CFR 21 Part 11. The CORIS system does not record or transmit patient information, information on samples or specimens, or other identifying data from the lab. Only the temperature sensor readings, on/off states of external alarms, presence of water, CO2 levels, and motion detected are recorded. These readings are permanently recorded in the cloud (not in a local computer), and users cannot modify or delete any sensor readings or alert information stored in the cloud. CORIS reports are automatically generated and permanently stored, and cannot be modified or deleted by users. Authorities can use the reports to verify the integrity of the original readings.

IT and Security

Will my IT department need to put a “hole” in the firewall to allow CORIS equipment to communicate with the Internet?

No modification or configuration of the firewall is required. This is a unique feature of the CORIS system. CORIS has two network security patents that allow CORIS devices to communicate with its cloud servers without any new configuration or permissions in the firewall. If a new computer can connect to the Internet using its Ethernet connection, the CORIS Gateway modules will be able to communicate with our servers.

Do we need a dedicated server or other device for this system?

No, the system is cloud-based, so there is no local computer or server. This means your lab does not have to operate a computer, secure it, maintain it, back it up, or update any application software.

Does CORIS use Wi-Fi for communications?

CORIS does not use WiFi. We use LoRa wireless communications, which has much greater range and security.

Where is my data stored and how long is it available?

All data is permanently stored in our cloud-based servers, which are mirrored in multiple geographic regions, with automatic backup and recovery.

Can an unauthorized user intercept the wireless signal to read or modify the temperature readings?

Temperature readings are encrypted, and LoRa communications include enhanced security to guard against data capture.

Do we need to change passwords on a regular basis?

It is not required, but we do recommend regularly changing your password.


How will staff and researchers be notified when there is a problem?

Alerts are sent to users via email, text message, and/or phone call, based on user preference. Each user can customize how they like to receive alerts based on time of day, day of week, or severity of the alert.

How quickly will we be notified if one of my alerts is triggered?

Alerts are sent immediately once the alert conditions are triggered. Alerts are triggered by both the temperature and the time interval that the temperature exceeded its limit, e.g. the temperature has been warmer than -75 degrees C for more than 15 minutes.

Can alerts be sent to multiple people for the same problem?

Yes, there is no limit to the number of people who can receive alerts.

Can alerts be repeated if no one acknowledges them?

Yes, you can customize how frequently alerts are repeated with no response.

Can alerts be escalated if conditions worsen?

Yes, there are three levels of severity for alert conditions, and different people can receive different severity alerts. This is highly customizable to suit your lab’s personnel, including multiple conditions that trigger each level of severity.

I work in a large lab. Can I receive alerts just for the freezers that store my specimens?

You can define which freezers, LN2 tanks, refrigerators or incubators for which you want to receive alerts, so you will not receive alerts for other freezers in your lab that may have problems.
