Alat Ukur Kualitas Udara

The Delta OHM wireless data logging system allows the monitoring of many physical quantities in various application fields.

The data loggers are available for the monitoring of: – Temperature – Humidity – Atmospheric pressure and differential pressure – Illuminance (lux) – UVA, UVB and UVC irradiance – Carbon monoxide (CO) – Carbon dioxide (CO2) – Solar radiation – Rainfall quantity – Wind speed and direction – Leaf wetness – Soil volumetric water content – Level – WBGT index. The models that measure relative humidity and temperature calculate derived humidity quantities. The calculated quantities depend on the model and can be: Dew Point, wet bulb temperature, absolute humidity, mixing ratio, partial vapour pressure. Depending on the model, the external measuring probes are connected to the data logger via M12 connector or screw terminal header. Some of the models are equipped with built-in sensors.

Data loggers with terminal header inputs are available for the connection of: – Transmitters with 0÷20 or 4÷20 mA current output and 0÷50 mV, 0÷1 V or 0÷10 V voltage output – Pt100 / Pt1000 and K, J, T, N, E type thermocouple temperature sensors – Sensors with voltage free contact output (counting of switchings) or potentiometric output – Sensors with RS485 MODBUS-RTU output. This allows to extend the monitoring capability of the system to countless other quantities, in addition to those listed above.
