THE DIGITAL ACCUMEASURE SERIES HAS AN ULTRA-COMPACT DESIGN UNIT WITH CAPACITY FOR UP TO 4 CHANNELS IN A HOUSING VERY SMALL HOUSING WITH ONLY 2″ (53MM) H X 4″ (103MM) W X 4.7″ (120MM) D. ACCORDING TO PUBLISHED SPECS, THE DIGITAL ACCUMEASURE OFFERS 5X BETTER STABILITY THAN MICROEPSILON DIGITAL 6500 PRODUCT. ALTHOUGH THE MICROEPSILON DIGITAL 6500 PRODUCT HAS UP TO 8.5KHZ FREQUENCY RESPONSE IN TOTAL, ITS BANDWIDTH DECREASES WITH THE USE OF EVERY ADDITIONAL CHANNEL. FOR EXAMPLE, A 4 CHANNEL MICROEPSILON DIGITAL 6500 WOULD ONLY PROVIDE ABOUT 2KHZ FREQUENCY RESPONSE WHEN IN SIMULTANEOUS USE. IN CONTRAST, A 4 CHANNEL DIGITAL ACCUMEASURE PRODUCT WOULD PROVIDE 5KHZ FREQUENCY RESPONSE PER CHANNEL WHEN CHANNELS ARE USED SIMULTANEOUSLY. WHILE BOTH UNITS HAVE THE ABILITY FOR USERS TO PERFORM MATH FUNCTIONS, THE DIGITAL ACCUMEASURE HAS AN ADDITIONAL SOFTWARE MODULE AT NO EXTRA COST TO MEASURE NON-CONDUCTIVE TARGET THICKNESS WHICH THE MICROEPSILON DIGITAL 6500 DOES NOT.

The Digital Accumeasure series has an ultra-compact design unit with capacity for up to 4 channels in a housing very small housing with only 2″ (53mm) H x 4″ (103mm) W x 4.7″ (120mm) D. According to published specs, the Digital Accumeasure offers up to 4X better stability than MicroEpsilon Digital 6500 product while providing more than 2.5X resolution. The Digital Accumeasure Series is up to 20X more stable than the MicroEpsilon Digital 6220. The Digital Accumeasure Series has 5kHz frequency response while the MicroEpsilon Digital 6220 can provide only up to 1.5kHz. While both units have the ability for users to perform math functions, the Digital Accumeasure has an additional module to measure non-conductive target thickness which the MicroEpsilon Digital 6500 does not.
