Designed for laboratory and test environments, the PC9 digital milli-ohmmeter from H.Tinsley measures resistance over six selectable ranges from 20mOhms to 2kOhms.
The PC9 digital milli-ohmmeter from precision instrument specialist H.Tinsley measures resistance over six selectable ranges from 20 mOhms to 2 kOhms.
Equally suitable for resistance measurement where inductance is also present the unit's high sensitivity also enables it to be used for low resistance work.
Designed for laboratory and test environments, its use covers resistance measurement in cable joints, earth bonds, switches, motors, transformers, generators and other applications.
The six selectable ranges are 20 mOhms, 200 mOhms, 2 Ohms, 20 Ohms, 200 Ohms and 2 kOhms with accuracy to +/-0.1 percent at currents up to 1A.
Read-out is on a four digit LED.
A four terminal measurement method eliminates errors that would normally occur due to test lead resistance, and the circuitry used achieves measurement much faster than traditional bridge techniques.
Additionally the PC-9 has a range holding facility to further reduce the measurement time for components of similar values.
Internal digital calibration is provided and each unit has a certificate of conformity.
Kelvin type test leads are supplied.
Established in 1904, Tinsley is UKAS accredited and manufactures to ISO9001 quality standards.
The company produces a wide range of high quality precision instrumentation that it supplies to world markets.
