VisiPro DO Ex 225 H2 (discontinued)

The discontinued VisiPro Optical DO sensor family was designed for industrial environments with standard and Ex versions for use in explosive environments. Hamilton's own substitutes VisiFerm mA and VisiTrace mA meet and exceed the specification and performance requirements and reduce the effects of ageing and temperature with 100% backwards compatibility to existing installation. VisiFerm mA and VisiTrace mA are delivered with Ex approval as standard. Find our equivalent replacement sensor here:
