SEKO’s range of probe holders offers safety, reliability and convenience when it comes to measuring pH, ORP, dissolved oxygen and conductivity. The product range extends from immersion, in-line and continuous flow supports, up to fully-automated calibration and cleaning systems. For correct operation, the probes must always be installed using supports that ensure correct mechanical protection and the degree of impermeability. The probes can be immersed in tanks, inserted in pipes or placed in sample collection containers.
