Underwater Light Meter

Listing ID #4162625

Direct digital readout displays instantaneous sensor output of 15 second averages. Measures µmol, lux k lux or Wm-2. Meter automatically selects range with best accuracy and resolution for a given input signal so that measurements can be made in a variety of light environments. High quality amplifier provides automatic zeroing capability and long term stability. Calibration multipliers can be entered easily, and two sensor multipliers can be stored in memory.
