The EIT PowerMAP II is a Profiling Radiometer that provides the irradiance (W/cm²), energy density (J/cm²), irradiance profile (Watts/cm² as a function of time) and temperature profile (°C as a function of time) in a new instrument from EIT. This compact, one-piece instrument is 60% smaller than the original EIT PowerMAP and measures UV in four (UVA, UVB, UVC, UVV) EIT spectral regions. The product features larger internal memory for more data gathering, and rapid transfer of data to our new UV PowerView Software III graphic data analysis program via USB interface.

Profiling Radiometers such as the UV PowerMAP II provide an extensive “picture” of the UV source(s) and how the UV is delivered to the cure surface. The irradiance (W/cm²), energy density (J/cm²), irradiance profile (Watts/cm² as a function of time) and the temperature profile (°C as a function of time) are available when the data is transferred to the computer. Profiling radiometers quickly and easily identify:

• The number of lamps and bulb type in each position

• Lamp focus/Changes to the focus

• Process speed and/or exposure time variations

• Uniformity of the UV across bulb length

• The performance of individual lamps in multi-lamp systems

• Maintenance needs before they impact product quality

• System changes over time with the comparison to stored files

Features:

• Size: The PowerMAP II is approximately 60% smaller than the original EIT PowerMAP. Its small compact size of 5.5” x 2.1” x 0.55” (13.8 cm x 5.3 cm x 1.27 cm) allows it to measure UV in areas such as molding lines or chill drums that were not previously accessible

• Instrument Responsivity: The PowerMAP II is currently available with EIT UVA, UVB, UVC and UVV in a 10 W/cm² dynamic range

• Sample Rate: Instrument has a user adjustable from 128-2048 (Hz) samples per second

• Temperature Measurement: The unit supports a J-type thermocouple that is included with the system at a sample rate of 32 Hz

• Memory Capacity: The PowerMAP II memory supports 65 minutes of data collection time

• Battery: Typical battery life is 100 minutes. Battery is rechargeable via a provided smart charger. With the smart charger, the battery charges in fast mode (+/- 90 minutes). The time to charge via a computer USB port is dependent on USB port

• Pause Mode: Allows the user to ‘pause’ the PowerMAP II to collect information on up to eight different UV systems before transferring the data to a computer. When using Pause Mode, the collected data will automatically be broken into individual files. Example of the file structure is shown below
