Brick Color’s Heat Absorption: Science Experiment
The next science experiment my children did (see previous experiment) was to test the heat absorbing quality of bricks. Paper is thin and doesn’t have a large thermal mass – but bricks are thick and heavy. Would a dark brick be different compared with a light brick. The experiment involved little towers of half a […]
Science experiment 1: Heat absorption depending upon colour
Over the last couple of years my children have been involved with numerous science experiments. Since I sell temperature loggers, they have reaped the benefits of having access to many sample units. So the first son did a simple colour experiment where he placed a Thermocron temperature logger between sheets of coloured paper and hung […]
Temperature Logger Specifications: Part 2
Starting options Temperature loggers often offer a range of techniques to start the logging. Most loggers provide an immediate start capability via the software. A manual start option (normally a push button) is useful for where the loggers are stored for some time before use and a PC is not available. For example a farm […]
Temperature Logger Specifications: Part 1
In this final part on temperature loggers we investigate the other specifications and features that differentiate temperature loggers and thermometers. Software The great benefit of loggers is the ability to view the results and save them for later use. Each logger will typically have its own software. They vary in what the software can do […]
Temperature Logger – Sample rate and memory
This part continues exploring the jargon involved with temperature loggers and focuses on the sample rate and memory size. These are critical because they determine how long a logger can be used for before information is lost. Sample rate This is how often the logger will record the temperature. Most loggers offer a programmable sample […]
Temperature Logger discrepancy – “But why don’t they agree?”
A very common question is “why don’t two monitoring devices show the same temperature?” For example a fridge may have a digital display and a temperature logger but they never show the same temperature. Is the logger discrepancy showing the logger is wrong, because surely it must be impossible for them to both be right? […]
Temperature Measurement: Sources of Errors
It should be noted that the accuracy of temperature measurement is dependent upon a number of factors. They are: The instrument: The device itself will cause errors because of limitations in digital processing and physical issues (eg “cold junction compensation” with thermocouples). Sensor: The sensor is often the greatest source of error in the reading. […]
Temperature Loggers: Accuracy versus Resolution
Resolution The resolution is an indication of how specific the answer is. It is measured in degrees. The smaller the value, the better the device. For example, a resolution of 0.5° means that a reading of 3.5° could be between 3.25° and 3.75°. A resolution of 0.1° means that a reading of 3.5° could be […]
Applications of Temperature Loggers
Temperature loggers have been used to monitor refrigerators and freezers for many years now. They can also be used for display and serving areas. This provides critical information on how your equipment is operating. There is also a rapidly growing demand to monitor individual pallets or boxes. This then allows the user to detect if […]
The Benefits of Temperature Loggers
Find the cause Since the time and date are recorded it is possible to tell when temperatures occurred. From this it may be possible to determine who was in possession of the item, or who was working at the time. This information can then be used to help place the responsibility on the correct party […]
