CaNaRy - Hydrogen sulphide meter

CaNaRy is designed for pumping stations and other sewage related applications

Standard 4-20mA signal
CaNaRy converts measurements of hydrogen sulfide to a standard 4-20mA signal
Replaceable measuring cell
CaNaRy is developed with a replaceable measuring cell
Fully calibrated
CaNaRy is delivered fully calibrated and ready for installation

CaNaRy measures h2s in gaseous form

ACOWA CaNaRy is a unique hydrogen sulfide meter that can measure hydrogen sulfide in gaseous form at concentrations from 0-300ppm, and converts this to a standard 4-20mA signal.

CaNaRy is delivered fully calibrated and ready for installation with a 10m cable and does not need to be calibrated for the entire lifetime of the cell. The lifetime is expected to be 2 years minimum.
