As the times are changing, people are slowly moving away from paper chart recorders and preferring digital data loggers for many purposes including checking temperature and humidity. Chart recorders are being replaced by digital data loggers as they are economical. Data loggers automatically archive and collect data and no weekly maintenance is required.
The economic advantage of using a data logger can become even more visible after using it for the first year. Data loggers can make things go digital, unlike chart recorders. Data loggers make remote monitoring easy. Information like reports and graphs can be retrieved easily in real-time with the help of a desktop computer displayed in different locations at once and automatically gets backed up and archived.
Digital files can be annotated or analyzed automatically for reporting statistical values. A device that has sensitive moving parts can stop working at any time. The maintenance can be time-consuming and laborious in the case of chart recorders. As chart recorders use paper charts the amount of data recorded is limited to seven days.
If the charts are not changed observations are lost and the result might be invalidated. At times, the pens which are used in chart recorders can become leak or clogged, dry out, or run out which can result in loss of data. However, data loggers use digital memory which decreases the cost. Digital memory in data loggers can store data for months.
Digital features like scheduled downloading of data, and digital memory reduce the possibility of mixed readings to zero. Chart recorders draw continuous power and depend on power connection for operation there can be a possibility of a power outage. Data loggers are smart devices that operate on minimal current and can work on a single battery for many years.
Temperature and relative humidity variations and levels can affect the recorded measurement. The temperature and humidity need to be maintained within certain limits. This helps in achieving repeatable results, minimizing the expense of tedious corrections, and meeting the accuracy and regulatory requirements.
Old chart recorders cannot record humidity and temperature accurately to satisfy regulatory and quality requirements. Chart recorders are difficult to maintain. Data loggers use digital technology like solid-state sensors, advanced microprocessors, and full-featured software which increases accuracy. Data loggers give greater accuracy for a long time. They can also be moved to critical areas as they are portable and small-sized.
As we see, there are many advantages to choosing data loggers over paper chart recorders, and at G-Tek you can good quality data loggers at an affordable price and high-reliability rate.
