Product Introduction

STGEO-P250 Portable Laser Power Meter

User Interface

Key Features:

  1. POCKET-SIZE - This mid to high power laser probe is so compact it fits in your pocket!
  2. EASY-TO-USE - The touch screen color LCD allows for a friendly user interface. You can make a measurement with just the touch of a button!
  3. USER SETABLE - You can set the wavelength, brightness and screen orientation to adapt to your application.
  4. DATA LOGGING - Save your data to the internal memory and then transfer it to your PC over the USB connection.
  5. FROM LOW TO HIGH POWERS - Thanks to a low noise level and high damage threshold, the Pronto can measure powers from 0.5 W to 250 W.
  6. YAG AND CO2 CALIBRATIONS - The Pronto-250 comes fully calibrated: every wavelength between 248 nm and 2.5 μm (YAG), and a real calibration at 10.6 μm (CO2). The Pronto-250-PLUS has an additional calibration for Single-Shot Energy measurements.
  7. HANDS-FREE OPERATION - Place it on a flat surface or use one of the 2 threaded holes for safe use with optical stands.

Innovative Power Meter Offers Unbeatable Convenience

The measurement of laser power is quick and simple with our power meter. The hand held power meter is a low cost, lightweight alternative to bulky, two-piece thermopile power meters and probes, or traditional “meat thermometer” probes. Ideally suited for industrial, scientific, and medical applications, use it when setting up your systems, and as a service tool to ensure maximum performance of your laser system at any time.

Designed to measure power levels from 1 - 250W, the power meter measures output power from the ultraviolet to the far infrared. This makes it the perfect tool for checking the performance of your excimer, argon, diode, YAG, and CO2 lasers, to name just a few.

Automatic data hold and auto ranging make the power meter easy to use. Simply insert the sensor into the laser beam and hold in place for a few seconds. The easy-to-read LCD screen will then display an accurate measurement of average laser power. To take another reading, simply push the reset button, and the power meter is ready to go.
