| Model | Description |

| HD2021T | Transmitter for measuring the ILLUMINANCE |
| HD2021T | Transmitter for measuring the IRRADIANCE |
Measurement of solar irradiance, within 400nm
- 950nm spectral band (HD 2021T.1)
Monitoring tanning lamps irradiance within UVA (HD 2021T.2) and UV (HD2021T.5) spectral regions,
as well as efficiency control in filters for high pressure UV lamps.
Efficiency control in UV lamps used in water purification plants, where UVC (HD2021T.4) band irradiance
needs to be constantly monitored.
The HD2021T Transmitter for illuminance, luminance and irradiance series allows conversion of photometric
and radiometric quantities as illuminance (Lux), luminance (cd/m2) and irradiance
(W/m2) - across UV, UVA,
UVB, UVC spectral regions and 400-950nm band - into a 0 - 10 voltage signal.
The voltage output 0 - 10 V ( 0 - 1 V, 0 - 5V, 4
- 20mA upon request) comes factory set calibrated to the full
scale range specified at the time of order.
HD 2012T transmitters wide range of applications include:
Measurement of illuminance (HD 2021T ) and
luminance (HD 2021T.6) in offices and laboratories, manufacturing plants and production areas, commercial
sites, theatres, museums, sports lighting, roadway lighting, tunnels and nursery-gardening systems.
The HD2021T7 probe allows converting a photometric quantity such as the “equivalent veiling luminance” (cd/m2) into a current (4-20 mA) or a voltage signal
(0-10 V) according to the version that you choose.
If the acquisition station is far from the probe ( >50m), the current output version is required.
The HD2021T7 probe has IP67 protection.
