The Cropico DO4000 series of high performance, digital milliohmmeters are now available from Seaward. The series offers low-resistance measurement and improved quality control during turbine blade manufacturing.
The portable, rugged instrument includes a number of advanced features to ensure measurement accuracy. This includes forward and reverse current measurement with auto averaging, true-current zero, long-scale length, and a selectable measurement range from 40mW to 4kW with respective resolutions between 10mW and 1W.
Within the range, model 4001 also includes temperature compensation, with preset coefficients for copper and aluminum, plus user settable coefficients for other materials. Temperature measurement over the range –50 to +800ºC is also available.
Protection up to 415V rms is provided at the measurement terminals and push button operation is achieved easily by clearly marked function controls. Direct reading measured values are displayed on a four-digit LCD display.
Over range and low battery indication is also provided and warning LEDs illuminate when an open circuit lead condition is detected. The 4000 series can be supplied with long leads to allow for accurate measurement of large blades and a rechargeable battery option includes a battery pack, docking station, and charger.
The DO4000 forms part of a comprehensive range of precision measurement instruments available from Cropico, part of the Seaward Group.
