Functions

GMS 

plus

4.

4.2

General

The gas monitoring system GMS

plus 

 continuously measures the 

concentration of gas and the temperature in rooms. 

It is specifically designed for use in potable water and pool water 
treatment or for industrial use. 

Typical applications:

• Chlorine gas room monitoring in swimming pools
• Ozone gas monitoring in potable water disinfection systems.

The GMS

plus

 processes the signals from two gas sensors and up 

to two temperature sensors (Pt 1000) simultaneously.

Please note

The temperature measurements are not used for gas sensor 
temperature compensation. 

Inputs are integrated for alarm acknowledgement as well as for 
door contact switches to switch off alarms. An internal buzzer 
signals active alarms. 

The GMS

plus

 sends an optical or acoustic warning signal as soon 

as a set limit value has been exceeded.

Attention!

The installed acoustic signal transmitter (beeper) can only be 
heard in the immediate vicinity of the GMS

plus

. 

All alarms are indicated by an LED on the front membrane.

Sensors

The GMS

plus

 is operated with:

• Chloratect sensors
• Passive mA sensors
• Temperature sensors I/II.

Measuring ranges

Chloratect sensors

0 – 5 ppm / 0 – 20 ppm for Cl

2

 and ClO

2

0 – 1 ppm for O

3

Sensor I 
corresponds to

room I

Sensor II 
corresponds to

room II
