AL2021W
SINGLE CHANNEL H2O2 IN WATER MONITOR

 

Features:

Provides absolute calibrated concentrations for H2O2in a single measuring channel.

Fully automated operation using internal micro controller.

Automated calibration using liquid H2O2 standards.

Ranges :

0 to 30.0 µg/l

(free programmable)

0 to 0.300 mg/l

0 to 3.0* mg/l

H2O2 liquid phase detection limit of < 70 ng/l**

Rugged and simple to use.

RS232 link for remote access and control.

 


Instrument Specifications

The instrument has multiple, free programmable measuring ranges. The calibration can be defined by user within the ranges given below. Liquid phase measurements provides calibration by liquid peroxide standard for example:         

: 0 to 30.0  µg/l
: 0 to  300.0 mg/l
: 0 to 3.0  mg/l*

* Higher concentrations on request.

Detection limit:

< 0.07 µg/l**

equivalent to:  2 * 10-9 M

** only when calibrated for 30.0 µg/l

Noise (each channel)

< 2% at full scale

Time constant

40 sec (10-90%)

delay time 240 sec
