The YSI Model 63 Handheld pH, Conductivity, Salinity and Temperature System is a rugged, micro-processor based, digital meter with an attached pH, conductivity and temperature probe. The pH sensor can be easily replaced in the field.

The Model 63 has a non-detachable cable length of 10 or 50 feet. The probe body has been manufactured with stainless steel to add rugged durability and sinking weight.

A transport chamber, built into the instrument case, provides a convenient place to store the probe when transporting the system. The Model 63 case is waterproof (rated to IP65) allowing operation in the rain without damage to the instrument.
