Light Meter Calibration Procedure

In order for this meter to be exact you need to perform calibration.

Light meter calibration procedure.

Analysis of power and energy calibration errors4. Our iso iec 17025 accredited national institutes of technology nist traceable light meter calibration services will ensure that your instruments can be trusted for accuracy and repeatability. Incident light measurement reflected light measurement. It features direct reading in lux or fc and also displays the measured light color temperature in degrees kelvin k.

This data is then stored for easy 24 7 access within gagesuite. These service specialists also handle nist certification requests and liason with our in house calibration laboratory to make sure that certification is. Professional light intensity lux meter that measures illumination levels in lux. Light meter calibration light meters are utilized in a variety of industries and applications including photography cinematography osha compliance security quality assurance photosensitive materials regulatory requirements process controls and clean room standards.

Light meter calibration service acs calibration offers laboratory and on site light meter calibration services. As light meter calibration specialists all g r labs light meter calibration services are traceable to the national bureau of standards nist with a 0 5 in house standard for radiometric calibrations and an in house 1 0 traceability for photometric calibrations the 3 sigma accuracy to the calibrated probe is 3 0 maximum but g r labs standard is a 1 0 window from calibration. What actually happens in our 365nm standard for example is that the. Combination of errors and total error3.

Turnaround is quick in order to minimize inconvenience and downtime for the customer. We state our traceability to our in house 0 5 nist standard as 3. A full service team is staffed by experts in extech products. You get information like analog and digital light meter and the types of light meter.

Also light color measurement requires device with an rgb light sensor. Our light meter calibration procedure requires our experienced technicians to take measurements by direct comparison to a calibrated standard meter and reference source. This is to allow for the transfer from the nist standard to our secondary standards and then the transfer to the probe being calibrated. Detailed analysis of power and energy calibration errors.

This article describes all the important information regarding using a light meter. A big advantage of your external exposure meter is the incident light measurement which prevents object related incorrect exposures. This document discusses the interpretation and basis for stated measurement accuracy of ophir laser power energy meters 1. You can get the method to calibrate the digital light meter.

In contrast to the reflected light measurement of the camera internal exposure meters which measure the light reflected by the object the external exposure meter measures the light falling on the object. Acs calibration is committed to providing our customers with high quality light meter. They provide the repairs needed to keep your instruments accurate and at peak operation.
