The 2051/2052 series instruments consist of class 1.5 respective AC, DC, ammeter, voltameter. These instruments are excellent functional , making them suitable for labs at research centers and schools.
They are also very useful for factory setups and maintenance service.The special structural make them have two terminals position: upper or lower ( 2051 is lower, 2052 is upper)
Optional taut-band suspension system eliminates friction and provides strong resistance to shock impact
Features:
- Useful for both high -sensitivity and large- volume measurements
- DC: 30uA~30A, 0.3V~300V
- AC: 0.5mA~25A, 3V~300V
- Long scale and mirrored for easy accurate read out
- One hand held size and lightweight
