Gloss Meters

At NUNES Instruments you will find highly accurate digital gloss meters. Colour and gloss are two different and important parameters to determine the surface conditions and characteristics of the piece that lies in front of you and has to be measured. To ensure a homogeneous impression of a product that consists out of several components, the knowledge of the gloss value of each part is very relevant. Product examples are found for example in the automotive industry, where the components of the vehicle interior are manufactured in different stages of production and then are joined. In the end-product, with respect to their visual appearance, no difference between the individual components should be visible. To achieve this, the use of gloss meter is indispensable. These gloss meters measure colour and gloss to determine the surface characteristics of materials or components. They are easy to use, compact and are solidly built. Gloss meters are specially designed to take measurements on the spot or by professionals on the job and are highly valued by workers in technical services that must take test measurements offsite. These gloss meters can be used on different surfaces, may they be smooth, treated or untreated such as stone, wood, laminates, floors, etc. Principles of measurement of a gloss meter (IG series): Gloss is determined by measuring the reflection of light on a particular surface. This measurement takes the intensity of light reflected from a specific point onto a specimen surface into consideration. According to this, the surface gloss reading of glass with the previously calculated coefficient of 1,567 must indicate the value relative to 100. A plate of black glass is used as the reference surface for calibration with a value of 90 for a measurement of 60° and 84 for a measurement of 20°. If you can't find the gloss meters you are looking for, please contact us and we will help you find the best solution to suit your needs by calling our offices on: 09020607000.

Product Details:
Resolution0.1 dB
PowerOne standard 9V, NEDA1604 or 6F22 battery
Light measuring levers rangingFrom 0.01 lux to 20,000 lux

The 4 in 1 digital Multifunction Environment Meter has been designed to combine the functions of Sound Level Meter, Light Meter, Humidity Meter, and Temperature Meter. It is an ideal Multifunction Environment Meter Instrument with scores of practical applications for professional and home use. The Sound Level function can be used to measure noise in factories, schools, offices, airports, home, etc., checking acoustics of studios, auditoriums and hi-fi installations. The Light function is used to measure illuminance in the field. It is fully cosine corrected for the angular incidence of light. The light sensitive component used in the meter is a very Stable, long life silicon diode. The Humidity/Temperature is for use a humidity/semiconductor sensor and K type thermocouple.

Features:

    • 3 1/2 large LCD display with units of Lux, ºC,%RH and C & dB, A & dB indication

    Sound level range:
    • A LO (low) – Weighting: 35-100 dB

          Specification:

          VTCM conductivity meters includes measurement of conductivity temperature in liquids

           

          Automatic Calibration

          The meter is capable of calibrating up to 5 points using standard solution. From Setup Menu, choose CAL (Calibration) and press key to set known conductivity value, immerse conductivity electrode into calibration solution, press ENTER key and meter is automatically calibrated.

           

          Conductivity Auto-Ranging

          VTCM Series have auto-range function for measuring conductivity. Upon immersing conductivity sensor into sample solution, the screen immediately displays the value in appropriate measurement range for accuracy.

           

          Automatic Temperature Compensation

          Using the supplied temperature probe, the temperature value is displayed on the screen. The meter automatically compensates for optimum accuracy under variable temperature conditions.
