EJB 9970 Volt / mA CALIBRATOR

    The EJB 9970 Volt/ mA Calibrator for measuring 0 to 24 mA DC current loop (with very high accuracy of 0,015%) or 0 to 20 V DC voltage, it delivers outstanding performance, durability and reliability. 

    With a push button EJB 9970 is easy to use. It is EMI tolerant, dust and splash resistant, and features a removable battery door for quick battery changes. It is compact, lightweight, and easy to carry.
