Digital Pocket Colorimeter™ II Analysis Systems for Chlorine or Ozone (Hach)

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.
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.
•User Calibrations
Giving you the ability to create your own calibration curve, or to perform a standard adjust. Also manufactured are wavelength-specific ‘generic’ instruments, allowing you to enter your own methods using from two up to ten standards.

Pocket Colorimeter II: features and benefits

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.
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!
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).Ordering Information 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.DW : USEPA accepted or approved for drinking water (additional steps may be required)
