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
  • 20,000 LUX range: 1,800-19,990 LUX display, 10 LUX resolution
  • 50,000 LUX range: 18,000-50,000 LUX display, 100 LUX resolution
  • 200 FC range: 0-186.0 FC display, 0.1 FC resolution

Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health

It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Lake Superior Algal Blooms Surprise, Highlight Need for More Monitoring

In 2012, for maybe the first time, Lake Superior got scummy. Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.  It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms. But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae. Not the usual suspects The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.

Unprecedented Changes are a New Challenge for Lake Tanganyika

*This is part two of a series on changing ancient lakes. See part one, Lake Baikal, here . Ancient lakes are facing a suite of rapid, unprecedented anthropogenic changes. While ancient lakes are spread around the world and vary widely from lake to lake, their incredible age, which can reach into the tens of millions of years, makes them unique resources to science. They host incredible biodiversity and long sediment records. They are vital sources of food and water for millions of people. In a changing world, ancient lakes’ value as scientific and natural resources and the incredibly diverse life they contain is under threat.
