General Questions

Log onto our website or mobile app, see what the trend is. If temperature is trending back into range, then relax, check again in 15 minutes. If temperature is still trending outside of range, then take corrective action as soon as you can. That usually involves transferring content inside stressed freezer, identify cause of problem, and contact responsible party. Do not forget to log all actions taken into our web app or via mobile app.

Top shelf on the door if for monitoring purpose, somewhere in the center of middle shelf in the freezer if for quality assurance and regulatory compliance purpose. The top shelf is usually the hottest area in a freezer. If the freezer is somehow compromised, temperature in this area rises the fast and earliest. However, temperature in this area also fluctuates the most and do not represent the typical temperature of whole freezer. If the door is frequently opened, temperatures in this area can be several degrees higher than other areas. So for temperature recording purpose, temperature sensor is recommended to be placed in the center a middle shelf inside the freezer, where temperature is most representative.

-10°C and -25°C for regular freezers, -65°C and -95°C for deep freezers, 8°C and 1°C for 4C cold rooms and coolers. And set up local delay of 5 minutes. These settings will filter out most transient temperature spikes while still catch real alarms in time. If you just start to monitor and record temperature in your freezers, you will be surprised how much temperature fluctuates, particularly if you place sensor somewhere close to the door, and set up tight thresholds, you will constantly get false alarms.

After running our system for a week or two, then you can take a look the plot of temperature log over this period, and decide what thresholds you want to set up. Particularly, you want to adjust the upper threshold according to your need and condition of each freezer. The idea is to not receive false alarms but get real alarms as early as possible.

It might be time to defrost your freezer. Thick frost on freezer walls gives internal temperature measurement circuit a false sense of stable temperature which in return delays action of compressor. A defrost usually fixes the problem. If not, make budget for a new freezer.

Yes or No. The wireless coverage of base station is 20m/66ft in door. If another is not far from base station and there is not concrete walls and big metal object in between, most like you can. However, if you are not sure, you may want consider our onsite planning service or our base stations with high powered wireless radio.

Yes, you do. Assuming you have 5 freezers, we are looking at cost of 1 ~ 2 tubes of antibody. Preventing one accident among 5 of your freezers a year recovers the cost of monitoring service. It is good practice to care, know the temperature where carry out your experiment, store your reagents and samples.
Yes, absolutely. Our system works in the range of -95°C ~ 100°C. As long as the target temperature is inside this range, our system works. It has already been used for water baths, incubators and rooms. We also have scouts that can simultaneously monitor temperature and humidity which are particularly designed for room ambient environment monitoring, such as animal housing facility.
The is mostly due to difference in location of our sensors and location of freezers' builtin sensors. The tempearture can vary a lot in different parts inside a freezer. The other reason is some freezer manufacutre doesn't go as far as monitoring vendors do when it comes to temperature measurement.

Other Questions

Yes. The system is designed to cover every laboratories freezer no matter where it is located. As long as you have an Ethernet port that connects to internet where your freezers are located and a cellphone that can receive SMS, you are good to go.

As a matter of fact, we actually already have users outside United States. We even have a cluster of server in east asia to support our service there.

Yes, we think so too. We actually first built our prototype with a cellular modem. However, when it comes to coverage and operating cost, cellular connectivity is no match to Ethernet.
