How rugged are the IQ non glass ISFET meter systems?
The handheld field meters are encased in a shock-resistant holster and are engineered to withstand rugged environments. Some meters have a membrane keypad and are water-resistant, i.e. splashes and wet hands. The handheld field meter carries an IP rating of 65. Other water proof handheld meters such as the IQ 170 are completely waterproof with a rating of IP67. The probes are non-glass and manufactured from 316-grade stainless steel which resist corrosion, bending and breaking.
