New Product
RoHS compliant

The EL-WiFi-TH sensor measures the temperature and humidity of the environment in which it 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 30 days at 10 second sample interval). The range of the sensor can be increased by using WiFi extenders.

Our sensors require your wireless network to be IEEE 802.11b compliant.

Calibration Certificates

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.

A calibration certificate is not supplied as standard with a data logger.

Please note that a calibration certificate can only be provided with a data logger at the time of original purchase.
The EL-WiFI-TH is not supplied with software, however the control software is downloadable, free-of-charge from our website at the link below. The software is compatible with Windows XP, Vista and 7 (including 64-bit operating systems). Note, the software is not compatible with Mac or Linux.
