Durham-Geo® Stormwater Samplers

Innovative Sampler Designed for Ease of Use

Monitors rainfall precipitation rates and allows automatic collection of a storm water runoff sample after a predetermined amount of rainfall. Available commands include: set rainfall limit, reset rainfall count, run pump forward, run pump backward, enable/disable water sensor, enable/disable end of month reset, adjust time and date and show captured event.
Specifications: A dedicated microprocessor with two-button operation and a four-line LCD controls the sampler. Function, settings and current data are continuously displayed. The integral, 12V peristaltic pump is programmed to take a sample when the predetermined rainfall event occurs. The polyethylene sample bottle has a high water shut off float which activates when bottle is full. The reversible pump will then purge the sample line after the sample has been collected. The self-emptying rain gauge is connected to the sampler by a cable and plug, allowing the gauge to be located away from any overhead obstructions. The water level sensor is also connected to the sampler by a cable and plug, allowing the sensor to be placed in a pond, stream or other suitable collection area. The Storm Water Sampler is housed in a lockable, water-resistant ABS enclosure that may be inconspicuously located and secured on a construction site. Size: 6.7" x 11.4" x 17.4". Operating temperature: 32°–140°F. Includes: 20'L sample pickup tube with weighted stainless steel strainer, water level sensor with 20'L cable, one liter sample bottle, self-emptying tipping rain gauge with 40'L cable, rechargeable 5.0A gell cell battery and a 110V AC battery charger. Weight 16 lbs. Optional event logger (No. 111146) and software package (No. 113680) provides a continuous record of precipitation against time. Use Black Nylon Cable Ties to secure the pickup tube to a stake or steel rebar.
