The Extech Heavy Duty Light Meter enhances accuracy by selecting one of four lighting types: tungsten/daylight, fluorescent, sodium, or mercury. The meter utilizes precision diode and color correction filter, and adjusts for cosine and color corrected measurements. The microprocessor assures maximum accuracy through and Fc range of 200.0, 2000, and 5000Fc and a lux range of 2000, 20,000, and 50,000lux. 

 

The built-in RS232 serial interface provides a connection with the optional Windows Data Acquisistion Software that enables users to display and capture readings on a PC, and set time intervals and alarms. The battery operated datalogger module stores over 8000 readings for later transfer to a PC.

  • Circuit: custom one-chip LSI microprocessor circuit
  • Display: 3.5 digit (2000 count) LCD display with contrast adjustment
  • Measurement ranges: LUX: 0 to 50,000 LUX (3 range), Fc: 0 to 5000 Fc (3 range), relative mode: 0 to 1999%
  • Data hold: freezes displayed reading
  • Lighting types: Sodium, daylight/tungsten, fluorescent, & Mercury
  • Sensor structure: cosine/color corrected photo-diode meets CIE
  • Memory store/recall: records/recalls max/min/avg readings
  • Sample rate: 0.4 seconds (approx.) per reading
  • Zero adjust: push-button procedure
  • Auto power off: after approx. 10 minutes
  • Data output: RS-232 PC serial interface
  • Operating conditions: 32 to 122F (0 to 50C),< 80% RH
  • Power supply: 9 V battery
  • Power consumption: approx. 5 mA DC (approx. 200hr battery life)
  • 2,000 LUX range: 0-1,999 LUX display, 1 LUX resolution

Assessing Cumulative Risk From Water Pollutants

New research from scientists at the Environmental Working Group (EWG) shows that an approach that assesses cumulative risk from water contaminants could save lives. EWG senior scientist Tasha Stoiber spoke with EM about how the team developed the innovative new approach . “Our organization has worked extensively on tap water over the years, and an updated version of our tap water database was just released in 2017,” explains Dr. Stoiber. “We've been thinking about new ways to analyze that data.” Right now, the risk from contaminants in water quality is assessed one at a time—but that really doesn't comport with reality.

Custom ROV Helps Protect Rockfish in Puget Sound

Washington Department of Fish and Wildlife (WDFW ) scientists are using a customized underwater robotic vehicle (remotely operated vehicle or ROV) called the Saab Seaeye Falcon on a critical conservation study of threatened and imperiled rockfish. Dr. Dayv Lowry , a Senior Marine Fish Research Scientist, spoke to EM about using the ROV to facilitate rockfish conservation and recovery in the Puget Sound. “In the Pacific Northwest, the Washington and Oregon coast, several species of Rockfish have been fished for decades, with up- and downswings in abundance,” explains Dr. Lowry. “When fishing pressure decreases, and the stocks start to recover, we have gone back to fishing—the pendulum has swung over the years.

Monitoring Wilson Lake All Year Long from Underwater

Since the summer of 2018, Wilson Lake in Maine hosted a data buoy that contains a set of long-term environmental data loggers. The rugged buoy was specially designed for year-round use, monitoring dissolved oxygen and temperature even when it's locked in ice. University of Maine, Farmington biology professor Dr. Rachel Hovel spoke to EM about the Wilson Lake buoy and her team's work with its data. “The ability to generate a long-term data set and collect these data over the entire year is really useful, both in the classroom and for asking questions about what's happening in this lake,” comments Dr. Hovel. Although the Wilson Lake buoy has been deployed for just over a year, these kinds of deployments have the potential to be very long-standing. Dr.
