Stellar V2 Handheld Laser Power Meter
Handheld power and energy meter with interchangeable thermopile heads from 2 mW to 3000 W — 3.5-inch color display, 3600 mAh battery.
A handheld meter with a 3.5-inch color display and a family of interchangeable thermopile heads — built for incoming inspection, pre-dispatch checks, after-sales work and laboratory benches.
Why this series
- Head range covers 2 mW to 3000 W, with apertures of 18, 19, 25 and 50 mm
- Self-stabilising zero circuit — no zero adjustment before every reading
- Adjustable second-order acceleration algorithm for faster settling
- Optional single-pulse energy measurement (E-type heads)
- 3600 mAh battery: 12-hour charge, 24-hour working time
- Stores up to 1667 hours or 10,000 data points; waveform display on screen
- Metal body with shielding for use next to drives and power stages
- Burn-in protection for the probe when power exceeds the range
- Factory calibration with NIST traceability, plus a user self-calibration routine
- USB-B output with PC monitoring software
