The FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors are available in two models. Both are able to measure and log temperatures between -20˚C/-4˚F and +60˚C/140˚F, however, they differ in regards to their accuracies. For further information, please see the following table.
Product Code | Product Name | Sensor Type | Temperature Measurement Resolution | Temperature Accuracy |
EL-WIFI-21CFR-T | FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensor - Standard Accuracy | Standard Accuracy | 0.1°C (0.2°F) | Typical: ±0.3°C/±0.6°F (+5°C to +60°C/ +41°F to +140°F) |
Maximum: ±0.8°C/±1.6°F (-20° to +60°/ -4°F to +140°F) | ||||
EL-WIFI-21CFR-T+ | FilesThruTheAir EL-WIFI-21CFR-T+ Wi-Fi Temperature Data Logging Sensor - High Accuracy | High Accuracy | 0.01°C (0.02°F) | Typical: ±0.1°C/ ±0.2°F (+10°C to +50°C/ +14°F to +122°F) |
Maximum: ±0.15°C/ ±0.3°F (-20°C to +60°C/ -4°F to +140°F) |
In addition to logging temperature measurements, the FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors can be configured to include high and low alarms. When alarm limits are breached the data loggers will alert the user via an alarm indicator. Upper and lower alarms can be programmed when configuring the FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors using FilesThruTheAir’s free 21 CFR Wi-Fi Sensor Software. This software can also be used to connect the data loggers to a specified Wi-Fi network and subsequently the FilesThruTheAir 21 CFR Cloud (monthly subscription required).
Measurements are logged to the FilesThruTheAir 21 CFR Cloud via Wi-Fi. If the connection to the Cloud is interpreted the FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors will continue to log measurements until a connection is re-established (will log measurements for a maximum of thirty days at a sample rate of ten seconds).
Using the FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors with the FilesThruTheAir 21 CFR Cloud, allows the operator to maintain compliance with the standards detailed in the 21 CFR Part 11. As well as allowing the user to configure, monitor and manage multiple FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors, this app can be used to perform the following tasks:
These capabilities, make the FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors suitable for integrating into 21 CFR complaint systems when used with the FilesThruTheAir 21 CFR Cloud. As such these FilesThruTheAir EL-WIFI-21CFR-T Wi-Fi Temperature Data Logging Sensors are ideal for temperature monitoring applications within FDA-regulated industries, such as in the food and drug production sectors.
