Monarch PLS Pocket LED Stroboscope

Lightweight pocket LED stroboscope for diagnostic inspection and RPM checks — 30 to 300,000 FPM, cool-running LEDs, Li-ion pack (≈5–6 h typical), universal recharger, and NIST Traceable Certificate included.

Key advantages

30–300,000 FPM — 0.5–5000 Hz internal; 0.005% of setting or ± last digit accuracy class.
Bright, silent LEDs — average ~3300 lux @ 6000 FPM / 12" / 2°; no lamp replacements.
Tach / external modes — external trigger input; tach to 300,000 RPM; optional ROLS-P sensor kit.
NIST included — CE/RoHS; ¼-20 tripod bushing; 5 memory presets.

Typical applications

Visual diagnostic inspection of rotating/reciprocating machinery.
RPM checks and phase reference with external trigger.
Pocket strobe duty where a full-size Phaser/Palm Strobe is unnecessary.

Selection guide

6235-010 — PLS with LBC-U universal recharger; NIST certificate.
6235-011 Kit — Adds foam carry case.
6235-012 Kit Plus — Adds ROLS-P remote optical laser sensor + T-5 tape for tachometer use.
Flash duration — 0.5…1300 µs or 0.1…10° of rotation (auto with rate).
Power — Internal Li-ion 3.7 V / 2.4 Ah; charge 4–5 h; run 5–6 h typ. @ 6000 FPM / 2°.
Environment — 0…40 °C; weight 0.6 lb (0.27 kg) with battery.

Common mistakes

Ordering base PLS when Kit Plus (ROLS tach) is required.
Expecting continuous high-FPM / wide pulse width without checking battery runtime.
Ignoring external-trigger polarity/edge settings for sync work.
