Apogee UV Sensor & Meter

For measurement of UVA/UVB combined

Meter with internal sensor - MU-100

This meter measures the total UV radiation between 250 and 400 nanometers, and is measured in µmol m-2 s-1 (micromoles of photons per square meter second).

Meter with Seperate Sensor - MU-200

The ultraviolet meter and sensor with two meters of cable.

Sensor only - SU-100 (also known as the UVS)

The ultraviolet sensor only with two meters of cable. For use with datalogging systems


  • Display: (Model UVM and UVM-SS only) 3 1/2 digit LCD, 1.2 cm height.
  • Operating Environment: 0 to 50 °C. Less than 80% relative humidity up to 30 °C; Less than 70% RH from 30 to 50 °C. Sensor head on Model UVM-SS can be submerged underwater.
  • Power: (Meters only) Standard 9V battery. Battery life is typically 100 hours with the carbon-zinc battery (included) and 200 hours with an alkaline battery.
  • Dimensions: Meter - 126 x 70 x 24 mm; Sensor: 24 mm diameter, 25 mm tall
  • Sensor Cable: (SU-100) 2 meters of shielded, twisted-pair wire ending in pigtail leads
  • Range: Meters 0 to 199.9 µmol m-2 s-1, Amount of UV in full sunlight = 170.0 µmol m-2 s-1



Leveling Bases

The AL-100 is required for sensors on cable.

The AL-210 is used for mounting meters with integral sensor.

AL-100 Solar Sensor Leveling Plate
Carry Case The AA-100 carry case is an optional accessory for protecting meters in the field AA-100 Front
Mounting Brackets

The AM-110 fits the AL-100 leveling base and can be mounted directly to a mast or pipe with an outer diameter of 33-53 mm.

The AM-001 is designed to fit to the back of a meter for mounting a sensor on cable.
