Using Data Loggers to Document Temperature
 by: Rick Kaestner


Data Loggers

A temperature or temperature/RH data logger with an LCD display like the ThermaViewer is vital for anyone who needs to monitor and document temperature. The ThermaViewer performs the following functions:

1. Meets accreditation and customer requirements: FDA, ISO 17025, JCAHO

2. 24/7 Alarming provides an early warning for out-of-spec temperature conditions which triggers an auto dialer and local alarm .

3. Bullet proof data storage (you never lose data!): Each data logger stores a complete copy of the records in its battery backed up RAM memory.

4. Immunity to power outages: Each data logger has two batteries to protect your data from power outages. A nine-volt DC battery and a smaller button cell battery.

5. Easy Installation: The ThermaViewer is easy enough for a 12 year old to install and use. It immediately begins to collect data when power is supplied. You can set the date and time and the display parameters in just a few seconds with the help of the Care and Use guide.

The most accurate and least expensive way to document temperature is with a data logger like the ThermaViewer. Data loggers come with or without an LCD display. A display is very useful because you can see the temperature history at any time without having to first download it into a computer. Data loggers without a display must be programmed by wiring them up to a computer.

Data loggers are programmed to sample and document temperature electronically. They collect data constantly and can be downloaded to a computer to generate a printed record to be reviewed or filed away.

The initial cost is not only less than a chart recorder. It last for years has no moving parts, requires no paper, pens or ongoing maintenance.
