In response to customer requests, OAI had developed a 254nm waterproof probe for sterilization or purification and is used with OAI’s Model 308 handheld UV Light Meter or Model 656 UV Intensity and Energy Meter. This probe can be used outside a chamber filled with water or used submerged measuring in water, as UV light can pass through water.

OAI has been a recognized leader for over five decades in UV Measurement. UV Meters and probes from OAI are in use worldwide.

]]> Model 308 UV Light Meter https://oainet.com/product/model-308-uv-light-meter/ Thu, 09 Sep 2021 02:53:07 +0000 http://oai.atomicdevbox.com/product/model-308-uv-light-meter/ Dependable and repeatable, the OAI Model 308 UV Light Meter is a precise, direct-reading instrument designed to measure UV light intensity. The Model 308 features detachable probes for use in the UVA, UVB, and UVC ranges, plus a high-speed serial port and is available with an optional software package that facilitates instant data logging of intensity mode, time, wave length, serial number, and calibration due date.

The Model 308 UV Light Meter is used in Photolithography, MEMS, 3D Printing, Packaging, and UV Curing & Sterilization. Accuracy of this UV Light Meter is within ±3% and measurement repeatability is within ±3 LSB (least significant bit). Like all OAI precision instruments, the Model 308 provides NIST traceable measurements. This easy-to-use light meter is auto-ranging from 0.1 to 1999.9mW/cm2 full scale when used with the 2000mW/cm2 probe. The linearity of the UV Light Meter in this range is at least ±.002%-6 LSB.

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

The Model 308 UV Light 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, high-temperature, detachable probe.

APPLICATIONS

Perfect for a wide variety of industries where the precision measurement of UV light is essential, the Model 308 is designed for any application requiring repeatable, reliable UV measurement.
