The Pocket Colorimeter II allows user calibrations, giving you the ability to create your own calibration curve, or to perform a standard adjust. We also manufacture wavelength-specific 'generic' instruments, allowing you to enter your own methods using from two up to ten standards.

Each Pocket Colorimeter II Instrument comes complete as a ready-to-use kit that includes a reagent set (pre-measured unit dose reagents), sturdy custom carrying case, and manual.

• Waterproof, Lightweight, Economical
• The Pocket Colorimeter II Instrument really can be carried in your pocket! Weighing in at only .23 kg (8.1 oz), it even floats if accidentally dropped in water.
• Accurate, Reproducible Measurements
• Despite accuracy comparable to a lab instrument, the low-cost Pocket Colorimeter II is simple enough to use that anyone can obtain reliable results.
• Factory-Programmed
• Each Pocket Colorimeter II Instrument is pre-programmed for one of more than 35 parameters; many are based on EPA-approved methods. No manual calibration is ever required. Simply zero the instrument with a blank, insert the reacted sample, and read the result.
• Improved Optics
• A long-lasting LED light source allows expanded ranges for ammonia, chlorine, chromium, copper, iron, and molybdenum, reducing the need for dilutions.

• All Pocket Colorimeter II Instruments offer benefits for easy handling and testing wherever you are -- field, lab, or plant floor.
• 1. Lanyard
• Added feature keeps cap and colorimeter together. No more worrying about lost caps.
• 2. Rugged Construction
• Tough, impact-resistant shell protects electronics and optics, for years of trouble-free operation.
• 3. Waterproof
• IP67 rating: the Pocket Colorimeter II can remain submerged at 1 meter for 30 minutes and still function properly. And the instrument is designed to float!
• 4. Datalogging/Recall
• Record 10 most recent data points, along with time of measurement. No more manual record keeping, no hassle with carrying paper and pen.
• 5. Range Indicator
• Indicates instrument range, or parameter being tested. Thanks to improved optics, measurement can be made in two ranges for a number of important parameters
• 6. Battery Charge Indicator
• Even with significantly improved battery life, all things come to an end. The battery icon alerts you when you need to replace batteries.
• 7. Menu Key
• Quick, simple menu navigation and selection.
• 8. Zero/Scroll Key
• Zeros instrument during measurements, scrolls menu options during other operations.
• 9. Read/Enter Key
• Press when measuring to read concentration directly. Also used to make menu selections during other instrument operations.
• 10. Power/Backlight Key
• Turn instrument on, turn display backlight on (save batteries by using only when required by low light conditions).
