The data logger in this video is by Cryopak, USA marketed under the brand name Escort.
This is Temperature and Humidity recording Data Logger manufactured by Cryopak, USA which can be simply operated by Start and stop buttons. The data logger has a LCD screen which will display current temperature, maximum and minimum temperature reached during the recording and the duration of these readings. The device can be programmed for high and low alert levels, upon reaching which colored L E D’s will indicate the alarms. The data can be simply downloaded as pdf reports.
You can see the various features here. It has an LCD display. It has L E D’s to indicate the alarm levels. These are the alarm indicators. Book marking and continuous recording options are available. There are different models with various memory capacities.
Once the device is connected to the U S B, the device automatically appears on the screen. In the upper portion, you can see the general details of the device such as Serial number, model number, memory capacity etc.
Over here you can set 4 levels of temperature threshold levels. You can enable or disable the alarms, set the value of the alert levels etc.

The Graph screen automatically appears indicating the entire duration of recordings.Now this is the histogram indicating the number of recordings versus temperature and humidity.This is the detailed table of the entire recording. You can see the date, time, temperature and humidity readings
Also you can see the high and low readings in different color pattern
This is the summary screen which will indicate various programming parameters and summary of readings including high and low levels
Now we will generate pdf report by clicking on this button. This is the pdf report. These blue and red circles indicate that one lower and two higher alerts were activated.
