Delta Ohm production is entirely carried out at our site in Italy where operate also our metrological laboratories (Ilac-MRA Accredia) accredited for: Temperature, Acoustics, Photometry-Radiometry, Pressure, Relative Humidity and Air Speed. Delta Ohm designs, manufactures and calibrates portable and bench-top instruments, process and industrial meters, current loop or voltage transmitters, data loggers and sensors since 1978. The range include measurement of the following physical parameters: Temperature, Air speed, Relative Humidity, Dew point, Pressure, Radiometry/Photometry (including UVA, UVB, UVC, PAR, PHOT, BLUE, V-Eff, Lux, W/m2);Instruments for Safety and Industrial Hygiene monitoring as Noise Level meters (I and II class), Building Acoustic Sound Sources, Vibration meters, Microclimate WBGT, Non coherent Optical Radiation monitor, Acoustic and Accelerometer calibrator;Water analysis instruments: pH, ORP, Conductivity, TDS, Dissolved Oxygen, Turbidity; Devices for Building Management (BMS) as Temperature and Humidity Sensor, Light Level Sensor, CO and CO2 controller, Heat Stress Meter, Anemometer, Wireless Dataloggers;Equipments for Green Energy such as Solar Radiation, Pyranometer, Solar panel temperature sensors, Pyrheliometer, Sunshine Duration, Wind Speed;Delta Ohm also produce devices for Weather Station and Agriculture such as: Albedometer (Secondary Standard, I and II class), Aspirated air temperature, Barometric Pressure, Rain Detector, Bucket Rain Gauge (200 and 400), 16 channel Data Logger, Global irradiance in the UVA, Global irradiance in the UVB, Leaf Wetness, Net-radiometer, Photometric probes LUX, Pyranometer (Secondary Standard, I and II class, Silicon), Pyrgeometer, Pyrheliometer, Rain Detector, Soil Moisture, Soil Temperature, Thermo-hygrometer, Ultrasonic Anemometer (2 & 3 axis);
