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.
