The Pocket II is a fast way to test chlorine that is compact, easy to use, and accurate.
• Portable/rugged: The Pocket Colorimeter™ II Filter Photometer is a true go-anywhere instrument. It's lightweight and battery operated, suitable for extended field work or quick, on-the-spot process monitoring. Weighing only .23 kg (8.1 oz), the tough, impact-resistant shell protects electronics and optics for years of trouble-free operation. The PCII is waterproof, lightweight and rugged. You can get clear readings even under difficult conditions, thanks to lighting and large figures on the display. Also, it has a IP67 rating so that the Pocket Colorimeter II can remain submerged at 1 meter for 30 minutes and still function properly. And, the instrument is designed to float!
• Easy to Use: The handheld pocket is a single parameter instrument so you can measure what you want to measure. Record 10 most recent data points along with time of measurement. No more manual record keeping hassles with carrying paper and pen.
• Accuracy: The PCII provides you with accurate results. The instrument has two channels in which measurements can be made. Each channel will accept a user-defined calibration curve. Up to 10 standards can be used to determine the calibration. The curve is generated by a point-to-point straight line segment between each standard used. Linear and non-linear positive or negative slope calibrations can be performed. A calibration curve may also be manually entered from the keypad if a previously determined curve has been made on the Colorimeter. At least two data pairs (concentration and absorbance) are required.
