Multi-parametric monitoring in one universal sensor


Mesa Labs’ VPx Wi-Fi Sensors feature an LCD screen with touch-button user interface which displays current readings and cumulative min/max since last reset, with local audible and visual alert capability. VPx Wi-Fi Sensors transmit wirelessly via Wi-Fi 2.4 GHz (802.11 b/g) radio transmission.  


Designed for use with a variety of exchangeable, external probes, Mesa Labs’ VPx Wi-Fi Sensors provide a single versatile interface for a broad range of inputs.  VPx Wi-Fi Sensors, inputs and alerting can be configured through web-based ViewPoint Software applications.  


The ViewPoint VPx Wi-Fi Sensor meets and exceeds the CDC’s Vaccines for Children (VFC) functional requirements, with an LCD display and local data storage of over 4,000 readings. Interchangeable measurement probes are supplied with an NIST or optional ISO-17025 calibration certification.
