UV-C Light Intensity Meter
UV-C light sanitizers are an effective means of getting rid of pathogens on surfaces, but how do you know if the UV-C dose is working?
Description:
The UV-C Light Intensity Meter provides a digital readout of the UV-C dose delivered to a surface in μW/cm².
It is an ideal tool for commissioning, verifying, and maintaining the operation of 254nm UV-C systems in a wide range of environments, from restaurants and hotels to food and beverage production and processing plants.
This intensity meter verifies that you are delivering a high enough dose of UV-C to inactivate pathogens with the clarity of a digital display that takes the guesswork out of how our UV-C sanitizing systems work.
Measure UVC Light Accurately
The UV-C Light Intensity Meter is a professional device for measuring the intensity of UV-C germicidal lamps, that is, the output of UV radiation energy per unit area.
The UV dosimeter is supplied with a one-meter test hook in line with the one-meter test guidelines set out in "WST 367-2012 Regulation of Disinfection Techniques in Healthcare Facilities" to ensure full compliance with testing standards.
The UV-C Light Intensity Meter has everything you need to start validating the light performance of your UV/germicidal/antimicrobial disinfection system.
The meter is specifically calibrated and configured to cover the region of the UV-C spectrum where most pathogens, including the COVID-19 virus, are inactivated.
No matter what light source your system uses, the UV-C Light Intensity Meter does the following at the touch of a button:
- Check the fluence and fluence rate of the emitted light
- Confirm the amount of light emitted
- Validate the amount of light delivered to a surface
The UV-C Light Intensity Meter is a feature-rich handheld UV meter that enables on-screen verification and data logging of light intensity from many types of UV sources for any disinfection application, including surfaces, water, and air, regardless of the type of UV source.
The detector is connected to a 1-meter cable to reduce the risk of tester exposure. The UV-C Light Intensity Meter can be used with a wide range of sensors to test ultraviolet light from 290 to 390 nm.
Features of the UV-C Intensity Meter
- The UV-C Intensity Meter is based on the 1-meter detection distance requirements set out in the “WST 367-2012 Health Care Facilities Disinfection Techniques Regulation” and a 1-meter test hook is provided.
- UV-C Intensity Meter has an intelligent statistical data function, real-time statistics of real-time power value, maximum value, minimum value, the average value of measurement data, measurement duration, and date of the test. The real-time clock function can be used to track the test date from historical data.
- The UV-C Intensity Meter can be set to turn off automatically after 0-10 minutes. Test data is automatically saved when the device is turned off, allowing for unattended testing. The #1 data displayed on the screen when the device is turned on is the latest test data.
- The UV-C Intensity Meter employs high-precision UV-C filters and professional UV sensors to eradicate the impact of light intensity in the UVA and UVB range on the data.
- The separate UV light sensor allows the user to measure UV light at an optimal position.
- With the Max Hold function, users have 3 ranges to choose from, making it convenient to use.
- The use of LSI circuitry provides high reliability and durability.

What is UV-C Intensity Meter?
The UV-C intensity meter is a UV light meter used to measure the intensity of ultraviolet radiation.
It is widely used for the maintenance and detection of various devices. The measurement principle of the UV-C intensity meter is the photoelectric conversion principle.
A UV intensity meter is an instrument used to test the intensity of ultraviolet radiation. So what is its operating principle?
How Does the UV-C Light Intensity Meter Work?
UV intensity meters usually comprise a silicon photocell or a selenium photocell and a microammeter.
A photovoltaic cell is a photovoltaic element that directly converts light energy into electrical energy.
When light strikes the surface of the sensor, the incident light passes through the metal film to reach the interface between the selenium layer of the semiconductor and the metal film, creating a photoelectric effect at the interface.
The size of the potential difference generated is proportional to the illuminance on the light-receiving surface of the photoelectric cell.
After reading the voltage value, the CPU measures the ultraviolet radiation according to a certain ratio and displays the data on the screen.
How is the Intensity of UV-C Light Measured?
When UV-C lamps or portable devices are used to disinfect objects and surfaces, it may be helpful to determine the UV dose delivered and compare it to the tables of doses required for the inactivation of microorganisms.
Irradiance from UVB or UVA light sources can be measured with our UV-C Light Intensity Meter. The dosimeter will display an intensity value measured in μW/cm² (microwatts per square centimeter).
With the UV-C light intensity meter turned on, the dosimeter should be placed in close proximity to the UV-C lamp at the same distance as when used to disinfect objects or surfaces. The meter displays the UV-C intensity in μW/cm².
Calculating the UV Dose
UV-C dose = UV-C intensity (μW/cm²) x exposure time (seconds)
Exposure time is the time the UV-C light is on and emitting UV onto a surface. Start with 20 or 30 seconds. The result of this calculation is a value that is expressed in µWsec/cm².
