P18 transmitter picture
P18 / P18D Humidity and Temperature Transmitter

P18 and P18D transducers are devices designed for the continuous measurement and conversion of relative humidity and ambient temperature into a digital or analog standard signals. The P18D transducer is equipped with an LCD display.

The transducers can be programmed through the RS-485 interface and free eCon software.
Sensor shields enable the application of the P18 and P18D transducers to operate in various ambient conditions.

The transducers are designed to be wall mounted.

Features:
-Calculation of dew-point, temperature and absolute humidity
-Analogue 4-20mA output of temperature and humidity, 0-10V output optional
-Minimum and maximum memory for humidity, temperature and dew point
-Programmable measurement averaging time,
-RS-485 interface with MODBUS RTU protocol.

H@20IoT picture
HT20IoT Humidity and Temperature Monitor

HT20IoT monitor has been designed to measure, monitor and record temperature and humidity. It is the perfect solution for applications where temperature and humidity levels are critical to the operation e.g.: in server rooms, drug and food warehouses, laboratories, museums or glasshouses.

The data captured by HT20IoT is stored in the internal memory and then sent digitally to the user (by the Ethernet MQTT).

In case of an emergency situation, the device immediately sends appropriate warnings via emails or via a website.

An additional advantage of HT20IoT is that it can be powered over the Ethernet in versions that are equipped with the Power over Ethernet system (PoE).
