The RH VC Analyser PRO combined Grading meter and F Stop timer will enhance darkroom productivity by assessing initial exposure and print grade, for BW printing then determining specific exposure times for specific areas of the print- removes need fro test strips 

• Take a reading from the brightest highlight and another from the deepest shadow -  thats all you need to do to get started- indicates exposure and grade - if outside of range of paper grade LED's flash - correct by altering Grade button until LED's stop flashing showing full Grey Scale range- then expose at indicated time and Grade
• Automatic test strip generation - incremental or full exposures
• Spot metering probe with built-in Densitometer function for reading relative negative densities - up to 8 spot readings - tonal value of each is displayed on the 15 step grey scale
• Timer exposure range 1 - 240 secs with steps in intervals of 1/3, 1/4, 1/6 or 1/12 f-stops
• 8 Channels for storage of settings for different papers or light sources
• Calibration kit for accuracy 
• Exposure range 1 - 240 secs - intervals of 1/3, 1/4, 1/6 or 1/12 f-stops
• Programmable burn in feature- 2 channels for split grade printing
• Manual override - see the expected results before committing a piece of paper
• Dry down compensation facility up to +/-20%
• Heavy duty construction and relays with gold plated switch contacts
• Switching capacity of 750 W (500W for 115v versions) suitable for most enlargers, including cold-cathode types
