Hydrogen Peroxide (H2O2) in Air and Water Monitor How to purchase this product...

The Model AL-2021 is a state-of-the-art digital Hydrogen Peroxide (H2O2) Monitor that is sold in several different application-specific configurations. Models are available for air or water H2O2 measurement applications. For applications requiring Hydrogen Peroxide measurements simultaneously at the input and output of an on-line process, two AL-2021s can be networked together.

Formaldehyde (HCHO) in Air and Water Analyzer How to purchase this product...

The ruggedly designed Model AL-4021 Formaldehyde (HCHO) in Air and Water Analyzer provides absolute calibrated concentrations for HCHO. A microprocessor fully automates its operation. The instrument employs built-in automated calibration using either the internal HCHO permeation source or liquid HCHO standards. Like the Model AL2021, it represents the state-of-the-art in low concentration level performance.  For applications requiring Formaldehyde measurements simultaneously at the input and output of an on-line process, two AL-4021s can be networked together.

Carbon Monoxide (CO) in Air Analyzer How to purchase this product...

The Model AL5001 Carbon Monoxide (CO) in Air Analyzer provides precise CO measurements where ultra fast time response and very low detection limits are required. Particularly well suited for aircraft measurements, its state-of-the-art performance puts it in a class by itself.

  • Very low detection limit: < 2 ppd s1/2
  • Ultra fast time response: (10-90%): < 1 sec
  • Sensitivity: >60 c/ppd
  • Linearity range (pulse counting): 0-20.000 ppd
  • Linearity range (analog mode):  0-200.000 ppd
  • Fully automated operation 
  • Automated calibration via external CO standard
  • Low weight for portable or aircraft operation
  • Rugged and simple to use
  • RS232-interface
