Web sensor - compressed air remote thermometer hygrometer with Ethernet interface, cable 1 meter

code: T3511P

Humidity, temperature transmitter. T+RH probe from hard anodized duralumin for compressed air up to 25 bars on the cable.

Humidity, temperature probe on a cable. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.

The device is supplied with T+RH probe with 1 meter cable.

WiFi Router Easy wireless communication using Web Sensor and optional  Wireless TP-LINK router.
