Tobias Associates, Inc. TQ-OP (Opacity Meter) Opacity Sensors and Instruments

Lightweight but accurate. Simple push-button operation facilitates density measurement; cordless convenience allows readings to be transmitted in any location. ","Opacity. Read the plastic material and determine the opacity,or the percentage of light that is not transmitted through the material. ","Density difference reading. Any density measurement can be stored as a reference. Subsequent readings will show the density difference from the stored value. ","Wider density range. TheTQ-OP reads film density values up to 6.00D with rock-like accuracy and stability,and calculates opacity from 0 to 100%. When the sample is placed on the aperture,illumination is instantaneous. Built-in crosshairs pinpoint target areas on the mini light table to ensure accurate positioning. "4 hours of fast charging; switches to trickle charge when battery is charging. Red/green LED shows charging status.","Thousands of readings per charge. Low battery warning when it's time to recharge. Also remove charge from charger if needed Runs 100% duty cycle. Automatically shuts off to extend battery life","RS-232 serial port. Use with printer to print hard copies,or with computer for analysis or data storage.
