The ProtEX-MAX Series delivers advanced digital metering and control functionality in fully integrated, explosion-proof enclosures designed for hazardous industrial environments. Built on the same proven architecture as Precision Digital’s most capable metering solutions, ProtEX-MAX meters are available in models that support a wide range of input types, including thermocouples, RTDs, 4–20 mA, 0–10 V, strain gauge, pulse, and discrete signals, along with extensive options such as relays, 4–20 mA outputs, serial communications, and 24 V transmitter power supplies. Certified as explosion-proof with CSA, ATEX, and IECEx approvals, ProtEX-MAX meters are offered in rugged aluminum or stainless steel enclosures for harsh operating conditions. Built-in CapTouch through-glass buttons allow the meter to be programmed and operated without opening the enclosure, helping maintain safety and compliance in hazardous locations, while RS-485 serial communication using Modbus protocol enables remote configuration and monitoring. With advanced capability, intuitive configuration, and a fully certified explosion-proof design, the ProtEX-MAX Series delivers reliable, high-performance measurement and control where safety and durability are critical.
