Ultra low temperature temperature and humidity recorder

The Ultra low temperature temperature and humidity recorder has an LCD screen that can display temperature and humidity data, device power and current network connection status in real time. Using WIFI wireless transmission, you can easily upload data online with the help of on-site network, and optional built-in battery power supply.

Original high-quality temperature and humidity measurement unit imported from Switzerland, the probe can be extended, and the probe line can be up to 30 meters long.

Upload data through WIFI, support intra-LAN communication, cross-gateway WAN communication, and support secondary development

Support dynamic domain name resolution DNS

Device parameters are configured through 485, which is simple and convenient

The temperature and humidity collection frequency is 2S/time, and the data upload frequency can be set from 1S to 10000S/time.

Built-in alarm function, the upper and lower limits of the alarm and the hysteresis value can be set

It has 2 normally open contacts and can be arbitrarily associated with alarm event output (optional)

Built-in one buzzer and one external audible and visual alarm (optional)

Can be connected to free local monitoring software platform, environmental monitoring cloud platform and YY version cloud platform

The equipment adapts to DC10~30V wide voltage power supply
