The Sigma Series DE is designed for applications that require reliable true RMS readings independent of waveform or harmonics. Sifam Tinsely’s patent iron vane movements come with sapphire jewels and hardened steel pivots, providing reliable readings, even in less than favorable environments that are susceptible to vibration or shock. Sifam Tinsley movements also offer outstanding meter performance, providing exceptional accuracy, tracking and repeatability.
Scales are easily interchangeable for maximum scaling flexibility. The scale display area allows for the use of large, easy to read numerals and divisions. The Sigma Series DE comply with DIN EN60051 (IEC51) requirements, with a standard accuracy of ±1.5% of full scale or better. The Sigma Series DE is available as 48, 72, 96 and 144 mm sizes and is manufactured from self-extinguishing polycarbonate.
