Digital Stat-Arc 2 IS is a meter designed for hazardous locations. It features a pulsing-beam range finder for always obtaining the correct reading, exclusive Auto-Zero circuit, HOLD button to capture transient readings, recorder output, and 40-hour battery life. It also provides drift-free accuracy even in ionized environments and has a charged plate adapter available. The Model 282IS is intrinsically safe and UL certified for use in Class I Groups A, B, C, D and Class II Groups E, F, G.
The Digital Stat‑Arc 2 (model 2821S) and Digital Stat‑Arc 3 (model 282A-1) are pocket‑sized, non‑contacting static meters that provide accurate, drift‑free readings up to 20 kV at a 1‑inch distance. They feature a pulsing‑beam range finder, auto‑zero circuit, HOLD button, and a 40‑hour battery life.
These meters are intrinsically safe (IS) and UL‑certified for various groups. They include a 9 V NEDA battery, LCD display with polarity readout, analog output (1 V = 10 kV), and a standard 3/32‑inch phone‑plug jack for external connections. Maintenance requires annual battery replacement and keeping the aperture clean.
