Reference grade instrument for use in all radiation therapy applications
One of the most widely used electrometers; the MAX 4000 Plus is a versatile, reference-grade tool ideal for a spectrum of radiation therapy applications.
New Look, Same Accurate Measurements
The MAX 4000 Plus overall design and display has been redesigned for easier set-up and a clearer output of measurements and data.
Low Noise, Repeatable Measurements
Exceptional 0.001 pA to 500.00 nA range, 0.01 pC to 999,999 nC range. 0.1% repeatability and exceptionally low leakage of less than 1 fA. Digital filter eliminates nearly all the effects of noise, resulting in stable, exact measurements.
Powerful Data Management
MAX COMM™ software allows for comprehensive control of dose and dose-rate measurements, chamber detectors, remote operations and data logging.
