Description
The 56-TR72A2-S is the high-precision model of the WiFi T/RH logger 56-TR72A2 — featuring the same autonomous WiFi transmission and cloud integration, but equipped with the included SHA-3151 high-precision sensor, which provides a wider measuring range and ±2.5 %RH accuracy.
Selected for GMP-validated environments and quality control departments where standard accuracy is insufficient: pharmaceutical manufacturing, stability chambers, calibration laboratories, and sensitive conservation activities in museums/archives. Encrypted HTTPS upload to the T&D WebStorage Service cloud, compatible with WPA2-Enterprise corporate networks.
Features
