Model 308T UV Light Meter

Built for high intensity applications, the OAI Model 308T UV Light Meter is a dependable, direct-reading instrument designed for measuring UV light intensity for UV curing. The Model 308T features detachable probes for use in the UVA, UVB and UVC ranges, plus a high-speed serial port. Accuracy of the meter is within ±3% and measurement repeatability is within ±3 LSB (least significant bit). Like all OAI precision instruments, the Model 308T provides NIST traceable measurements. This easy-to-use meter is auto-ranging from 0.1 to 1999.9mW/cm² full scale when used with the 2000mW/ cm² probe. The linearity of the meter in this range is at least ±.002%-6 LSB.

Power for the Model 308T UV Light Meter is supplied by a 9V alkaline battery and the easy-to-read LCD display consumes very little power for extended battery life. The Model 308T is very easy to use and features a peak hold switch enabling the user to capture the maximum intensity reached during an exposure and retain the reading on the display. OAI maintains a certified Calibration Laboratory to ensure that all products continue to meet specifications.

Detachable probes matched to specific UV curing spectral regions. The OAI Model 308T Meter is available with a family of calibrated detachable probes having spectral responses peaked in the UVA range at 365nm, 380nm, 400nm, 420nm, 436nm, and 540nm, the UVB range at 310nm and UVC range at 220nm, 253.7nm, and 260nm. Each detachable probe employs an ultra-stable silicon detector and special filters that precisely shape the spectral response. For added ease-of-use, probes are calibrated for direct reading without any additional adjustment. In cases where the measurements are to be performed in environments having significant infrared (IR) radiation levels, OAI can supply an optional high-intensity, detachable probe. These probes use special heat-resistant optics and silicon probe housing.
