Apogee Instruments' ultraviolet (UV) sensor provides a cost effective measurement of UV radiation.

 

Wide Range
Sensitive from 250 to 400 nm, spanning the solar UV range and UV output range of electric lamps.

 

Measurement Units
Calibration factors for photon flux density units [µmol m-2 s-1] and energy flux density [W m-2] are provided with each sensor allowing for rapid unit conversions.

 

Output Options
Analog and digital output options are available. Analog version is an un-amplified voltage output. Digital outputs include USB and hand-held meter. Digital "smart" USB sensor uses USB communication and custom software to interface directly to a computer. Hand-held meter has a digital readout and is avialable with a sensor integrated into the top of the meter or attached via cable.

 

Rugged, Self-cleaning Housing
The patented domed shaped sensor head facilitates runoff of dew and rain, helping to keep the detector clean and minimizing errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodized aluminum body and electronics are fully potted.

Typical Application
Applications include: UV radiation measurement in outdoor environments (sensor is not recommended for long-term continuous outdoor deployment), laboratory use with artificial light sources (e.g., germicidal lamps), and monitoring the filtering ability and stability of various materials.

Warranty and Support
All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.

+ Which UV Sensor model do I need?
All UV sensors use the same detector. The model number you need depends on which output is compatible with your datalogger. Model numbers are listed below with their output:
SU-100 0 to 40 mV
SU-420 USB/software
MU-100 Sensor integrated into top of handheld meter with digital readout
MU-200 Sensor attached to a handheld meter via cable with digital readout
+ Does the UV sensor measure UVA, UVB, and UVC? Can I get readings from just UVA or just UVB?
The UV sensor will detect all UVA, UVB and some of UVC, providing an integrated total of UV A, B, and some C radiation as one value. The UV sensor is sensitive to wavelengths from 250 nm to 400 nm. UVA is 315 to 400 nm, UVB is 280 to 315 nm, and UVC is 100 to 280nm. See the spectral response graph below.

UV Spectral Response

+ Is this sensor waterproof?
Unfortunately due to the nature of the way the UV sensor is built it is not waterproof.
+ Can I add additional cable to my sensor?
Yes, if properly spliced, the signal from the sensor is not affected by splicing on additional cable. We have tested splicing up to 100 meters of cable. For information on how to create a proper waterproof splice, please visit our Instructional webpage or watch our video.

We offer custom cable lengths of our high quality cable and splice kits that can be ordered at the time of purchase.

+ Do I need to order a sensor to go with my meter?
No. All Apogee meters (MO, MP, MQ, and MU series) either have sensors built into the meter or attached via two meters of cable. If you order a sensor only (SI, SO, SP, SQ, and SU series) you will need to have your own datalogger (or, depending on the sensor, a voltmeter) to collect information form the sensor.
+ Can I add cable to my meter?
Although it is possible to splice additional cable to the separate sensor, note that the cable wires are soldered directly into the circuit board of the meter. Care should be taken to remove the back panel of the meter in order to access the board and splice on the additional cable, otherwise two splices would need to be made between the meter and sensor head.
