Overview of the InTemp CX402-VFC series Temperature Data Logger

The InTemp CX402-VFC series of data loggers monitor temperatures in refrigerators and freezer where vaccines are stored. Ideal customers would be pediatric practices participating in the CDC Vaccines for Children program, hospitals, clinics, and WHO sites. These loggers communicate wirelessly via Bluetooth Low Energy to mobile devices. The loggers are set up and data is viewed using the InTemp app where you can easily view data, check the logger status, set alarms, and create and share secure PDF reports for maintaining regulatory compliance. The loggers feature an LCD display to view current temperature as well as the daily high/low temperature, advanced audible and visual alarm capabilities, and an internal temperature sensor for reading ambient temperature. The kit is available with external probes in 2- or 4-meter lengths. Additionally, the CX402-VFC series of loggers are unique in that they offer different sized glycol buffer bottles allowing you to use a buffer that best mimics the size of the vaccine vials you are monitoring.

When used with the optional CX Gateway (sold separately), you can receive remote alarm notifications in the event of a temperature excursion via text (SMS) and/or email.

Customer Questions
Can this send temperature information to my mobile device when I am not in the office? Or through the app can it alert if temps are out of range?

The InTemp logger can be set up to send alarm notifications but only through the use of the companion gateway app.  The app is currently only available for Android devices.  The way it works is you must have a mobile device running the app within range of the logger.  As long as the device is powered on and the app is running it will push out the alarm notifications.

 We also offer kits that operate on Wi-Fi that will send notifications without the need of a gateway app but they do require an active Wi-Fi network.

How do you determine what size Glycol Solution bottle is needed?

We generally recommend choosing a vial size that is closest to the vial size of the vaccines you are monitoring.  This will give you the most accurate representation of their actual temperature. 

Model CX402-VFC205 How long is the cord from the display to the probe in glycol? Is there an AC adapter or is it by battery only? What is the coldest temperature this will correctly work in? For example if the freezer gets down to -35 degrees Celsius will measure this with the same +/-0.5C Accuracy? Is there a USB port to allow downloading the data?

The sensor cables are available in either 2 or 4 meter lengths. There isn't an AC adaptor available for this product so it must be powered via batteries. The range of the logger is -30C to 70C. Using it outside this range will damage the logger. The +/-0.5C accuracy is from -22C to 50C. For details on this please see the specifications tab. The logger can only transmit data to the app which runs on a mobile device. There is no USB input on the logger. Once the data is loaded onto your mobile device you can forward it to the cloud service or to a desktop computer.

Does this thermometer have a low-battery indicator and programmable logging interval?


If this were to be used as a back-up, can a 2nd prob bottle be purchased? i.e. One to be kept in the refrig; one to be kept in the freezer? How much would an extra cost? Thanks.

The loggers only have a single input so you would need to purchase individual loggers for your fridge and freezers.

Most government sites do not allow for Wireless or Bluetooth can this device operate via ethernet or can you recommend one that supports Ethernet but can send TXT or email alarms to my device.

We don't offer any prebuilt vaccine monitoring kits that use a wired Ethernet connection however we can create one that does for you.

The T&D TR-71NW is a dual channel temperature logger that sends its data to the free T&D WebStorage Service Cloud and will send email notifications if an alarm condition is met.

We don't offer it on our site with the glycol buffer bottle but we would be happy to provide a quote with it built up that way.  The best way to proceed would be to send us a quote request mentioning that you would like a quote on this model kitted for vaccine monitoring use.  Because this model has two sensors we could build it up with two buffered sensors or just one.  You could use one for a fridge and one for a freezer with two buffered sensors or leave one sensor as is and use it for measuring ambient temps.  Just let us know how you want it configured when you contact us.

calibration due date ? does it come with a certificate

This devices comes with a 3-year calibration certificate that will expire at the end of the month 3 years from the month it was purchased in. Even though the certificate is good for three years, most states will only accept up to a 2 year calibration...
