Blue Sea Systems 1838-BSS M2 OLED AC Multimeter

Blue Sea Systems M2 OLED AC Multimeter (1838-BSS)

The Blue Sea Systems 1838-BSS is a high-precision, bright M2 OLED AC Multimeter engineered to monitor essential AC power parameters on marine, RV, and commercial power systems. Featuring a high-contrast, sunlight-readable organic LED display, it provides real-time monitoring of AC Volts (80V to 260V AC), AC Amps (0A to 150A AC), Frequency (40Hz to 90Hz), and Power (0 to 45kW).

Designed with an ultra-durable, waterproof IP67 front face, the 1838-BSS includes customizable high/low audio and visual alarms to alert operators to abnormal voltage spikes, line drop, or over-current conditions. The kit comes complete with an external AC Current Transformer (CT) coil for non-invasive, safe current measurement across single-phase or split-phase AC power lines.
