This digital UVX Radiometer is used with one of the three interchangeable sensors (ordered separately) for measuring 254nm, 365nm and 302nm UV
wavelengths. All sensors are calibrated with traceability to the National Institute of Standards and Technology (NIST) and UVP's published standards. In the UK or other European countries, traceability
to the National Physical Laboratory (NPL) is available. Recalibration of the sensors is recommended every six months at the UVP factory. Unit includes a port for attachment of a chart recorder (user
provided).
The UVX's range switch provides selection from three intensity ranges:
0 to 20 mW/cm2, 0 to 2000 microW/cm2 and 0 to 200 microW/cm2. The chart recorder port, standard on the UVX, allows for continuous
monitoring. The 10:1 attenuator extends the reading range up to 200mW/cm2. The UVX Radiometer is powered by a 9-volt battery for up to 120 hours.

The Multi-PulseTM MP-100
is an advanced optical radiometer designed to accurately measure UV, visible light, temperature and magnetic fields. Direct calculations of incident UV radiation at 302nm and 365nm for readings that are accurate and reliable. The MP-100 is ideal for determining radiation levels in a wide variety of industrial and scientific applications such as NDT, sterilization and semiconductor purposes.
This easy-to-use portable, handheld meter is designed with plug-in sensors for measuring the various options. Results are clearly shown on the LCD
which also indicates when the batteries are low. Battery (9V) life is typically 400 hours.
Optical and magnetic field sensors have accuracy set to +5%; repeatability at +1%. Temperature accuracy is +0.2% OOC from -20OC to +50OC.

These meters are photovoltaic devices for taking accurate and repeatable readings of UV light sources. Model J-225 measures the intensity of shortwave
UV (254nm). Each meter comes with a sensor, attentuation screen and filter. This meter's sensor is sensitive within a range from 220 to 280nm with maximum sensitivity at 254nm. Longwave readings are made
with the J-221 Meter. It's sensor is sensitive from 300 to 400nm with a peak sensitivity at 365nm. J-221 Meter complies with MIL STD 45662-A and can be found in MIL-I-6868D (NSN 6635-488-5451).
Each meter features two scales for low and high intensity readings. For remote readings, a four foot (1.2m) cord connects the sensor to
the meter. Two scales measure a wide range of intensity. An infrared filter assures accurate readings when measuring light sources producing infrared radiation. The 5X attenuation screen can be used for
very high intensity lamp measurements.
