BJZ Safe-STAT RM 4000
The BJZ Safe-STAT RM 4000 is a handheld teraohmmeter for measuring surface, leakage, and volume resistance. It is used to check whether materials and components are within the expected resistance levels in an ESD and quality context.
The instrument operates with two selectable test voltages, 10 V and 100 V, and measures in the range from 5 × 103 Ω to 2 × 1012 Ω. This makes it suitable for both low and very high resistance values. The measurement accuracy is stated as ±5%, providing an instrument that can be used for documented checks in practice.
Operation is via touchscreen, and results are stored on an SD card along with date, time, temperature, and humidity. This is a clear advantage when measurements need to be traceable afterwards, or when they are to be included in internal documentation. The built-in barcode scanner, or an optional RFID scanner, makes it easier to link a measurement to the correct item.
There is also an internal temperature and humidity sensor, so that ambient conditions are recorded along with the measurement result itself. This provides a more useful picture of the measurement, especially when working in environments where the climate can affect the result.
The compact size and the built-in lithium-ion battery power supply make the RM 4000 practical for inspection work in the workshop, in production, or during audits. It can also be powered via an external AC adapter.
