Lascar EL-WiFi-TP WiFi Temperature Probe Data Logging Sensor
The EL-WiFi-TP sensor measures the temperature of the environment in which the probe is situated. Data is transmitted wirelessly via a WiFi network to a PC and viewed using a free software package. During configuration the sensor will search for an existing wireless network whilst physically connected to the PC. It can then be placed anywhere within range of the network. If the sensor temporarily loses connectivity with the network, it will log readings until it is able to communicate again with the PC application (max 120 days at 10 second sample interval). The range of the sensor can be increased by using WiFi extenders.
The probe can be used in a wide range of temperature situations e.g. manufacturing processes, cold storage and hot storage.
This EL-WiFi-TP is a low powered battery device. When configured using typical sampling periods (e.g. once every 60 seconds) the sensor will operate for over one year. The battery can then be recharged via a PC or USB +5V wall adapter using the USB lead provided.
The software installed on the PC will allow set-up, data logging and data review. Set-up features will include sensor name, °C/°F, sample rate, and high/low alarms. Once configured, historic data can be viewed via the graphing tool or exported to Excel.
This sensor stands alone by itself on a horizontal surface and comes with a wall bracket that can be screwed onto a wall or flat surface. The sensor clips into the bracket. The sensor is supplied with a thermister probe with an attachment so that the probe can be securely fixed to flat surfaces.
The probe is removable so alternative probes can also be used to meet specific requirements providing they operate within the same temperature range.
All EL-WiFi sensors are thoroughly tested pre-release but the sensor may experience compatibility issues with certain WiFi networks.
The EL-WiFi-TP is suitable for a wide variety of applications, particularly where remote monitoring is important, these include:
- Environmental and weather monitoring
- Agricultural and livestock
- Food & drink
- Building & site monitoring
- HVAC
Lascar’s calibration certificates* are traceable to UKAS or NIST standards depending on your location. Customers in the Americas, or customers ordering through our US sales office will receive NIST traceable certificates generated in our ISO 17025 facility, whilst customers in the UK, EU, Rest-of-world or customers ordering through our UK headquarters will receive UKAS traceable certificates.
Certificates ordered through our online facility will be single-point tested at 25ºC and 50%RH. If you have a requirement for additional points, or require a different temperature or RH point, please contact your nearest Lascar sales office.
* Calibration certificates are not supplied as standard, and must be ordered separately.
