The FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers are available in two models with different accuracies. For further information, please see the following table.
Product Code | Product Name | Sensor Type | Temperature Accuracy | Temperature Resolution | Humidity Accuracy (@25°C) | Humidty Resolution |
EL-WIFI-21CFR-TH |
FilesThruTheAir EL-WIFI-21CFR-TH Temperature & Humidity Data Logger - Standard Accuracy |
Standard Accuracy | Typical: ±0.3°C /±0.6°F (+5°C to +60°C/ +41°F to +140°F) | 0.1°C (0.2°F) | Typical: ±2% RH (20% RH to 80% RH) | 1.0% RH |
Maximum: ±0.8°C /±1.6°F (-20°C to +60°C/ -4°F to +140°F) | Maximum: ±5.0 % RH (0 % RH to 100% RH) | |||||
EL-WIFI-21CFR-TH+ | FilesThruTheAir EL-WIFI-21CFR-TH+ Temperature & Humidity Data Logger - Standard Accuracy | High Accuracy | Typical: ±0.2°C/ ±0.4°F (+5°C to +60°C/ +41°F to +140°F) | 0.01°C | Typical: ±1.8%RH (10% RH to 90) | 0.1% RH |
Maximum: ±0.8°C/ ±1.6°F (-20°C to +60°C/ -4°F to +140°F) | Maximum: ±4.0% RH (0% RH to 100% RH) |
Both models are able to measure temperature between -20°C and +60°C (-4°F and +140°F), and relative humidity between 0 and 100% RH; they will log measurements to the FilesThruTheAir 21 CFR Cloud (monthly subscription required).
Measurements are streamed to the FilesThruTheAir’s 21 CFR Cloud via Wi-Fi. Connections to the specified Wi-Fi network, and by extension the 21 CFR Cloud, are made during configuration. The user is able to configure the FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers using FilesThruTheAir’s free 21 CFR Wi-Fi Sensor Software. Once connected to the Wi-Fi network the FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers can be placed anywhere within its range. If the connection to the Wi-Fi network or the 21 CFR Cloud is interrupted the FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers will continue to record measurements until a connection is re-established (for a maximum of thirty days at a ten-second sample interval).
Furthermore; using the free FilesThruTheAir 21 CFR Wi-Fi Sensor Software, the user can also program the FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers to include high and low alarms. The loggers will alert the user when an upper or lower alarm limit has been breached via an alarm indicator.
When the FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers are used with the FilesThruTheAir 21 CFR Cloud, they become suitable for integration into 21 CFR compliant systems. The FilesThruTheAir 21 CFR Cloud not only allows the user to monitor, manage and configure multiple data loggers but also facilitates his/her ability to maintain compliance with 21 CFR Part 11 regulations. As such the user is able to perform the following tasks using the FilesThruTheAir 21 CFR Cloud:
The FilesThruTheAir EL-WIFI-21CFR-TH/+ Temperature & Humidity Data Loggers are ideal for temperature and humidity monitoring applications in industries, such as food and drug production, that are regulated by the FDA.
