KEY POINTS & INTENDED USE

The SteriPEN Adventurer Opti water purifier is equipped with a new optical

water sensor for reliable performance so you can enjoy clean, purified water on

the go.Features and optical water sensor that detects whether or not the device

is in water and only allows the UV lamp to activate when the SteriPEN is

immersed in water. The optical sensor can also be used as a small light when

trying to locate the water source. The flashlight mode is activated by pressing

and holding the single button for 3 seconds. The lamp cover diffuses the LED

light.

UV water purifier. This is a compact travel oriented model. Steripen uses short

wave UV light to disinfect water. The UV light disrupts the DNA within bacteria

viruses and protozoa, rendering them harmless. Steripen isMORE

intended for use, and is most effective, in CLEAR water. However, Steripen has

been shown to REDUCE microbial contamination in turbid water. Follow detailed

instructions if using in turbid water and choose other water treatment options

if you expect to encounter turbid water.

To use Steripen: remove lamp cover, select treatment dose (.5 or 1L), immerse

lamp in water(UV lamp turns on when sensors on the pen body detect water)

agitate or stir water until UV lamp turns off and indicator lights signal

successful completion of treatment. Agitation is required to ensure that water

is fully exposed to UV radiation. Treatment of .5 litres is completed in approx

45 seconds, 1 L in approx 90 seconds. See instructions for detailedMORE

description of indicator light functions. UV lamp life is approx 8000 treatment

Steripen Adventurer uses two CR123 lithium batteries. Manufacturers tests

indicate that disposable CR123 will treat approx. 50 litres of water and 750mAh

rechargeables will treat approx.25 litres. Colder ambient temperatures will

negatively affect the number of doses per battery charge.In cold conditions

store batteries in pocket or other warm location improve performance.

Turbidity and Steripen - two pages of notes follow

Turbidity is a measure of water clarity as effected by the presence of

suspended solids. It is difficult to communicate a particular level of

turbidity in a written description. Steripen has been successfully tested in

water with a turbidity measurement of 33 ntu. If viewing 33ntu water in a clear

1 liter bottle, Steripen has provided the following descriptions of how one

might characterize the water:

Much closer to clear than opaque, Obviously not clear, Obviously cloudy, Object

viewed through the water are visible but blurry, As cloudy as weak lemonade

more

If clear water is not available, first try to filter the water to clarify it.

If the particulate is not too fine, allowing the water to stand will sometimes

be helpful. If it is necessary to treat turbid, murky or cloudy water in an

emergency situation, use the Steripen as follows:

- to treat 1 liter of turbid water, use two one-liter treatments.

- to treat 0.5 liters of turbid water, use a single 1 liter dose.
