Standards for digital ISE sensors

Combination standard 1
Combination standard 2

Combination standards with high or low concentration to test IQ Sensor Net ISE sensors AmmoLyt®, NitraLyt® and VARiON®

  • Checking the electrodes for the highest operational safety
  • With high or low concentration - adapted optimally to your application
  • A standard for all parameters

The combination standards VARiON®/ES-1 and ES-2 are optimally suited to check the WTW ISE sensors AmmoLyt®, NitraLyt® and VARiON®. This quick method is very suitable for the examination of the incline and the potential position of the measuring chain whether they are within their permissible limits. As these are combination standards, all electrodes can be tested at the same time.


Model Description Order no.
VARiON®/ES-1 Combination standard 1 (low concentration) 107050
VARiON®/ES-2 Combination standard 2 (high concentration) 107052
