The Crystal Engineering NV-4AA-RTD100-1KPSI-BARO is a multifunction data logger designed for professionals who demand precision and durability in the field. This versatile instrument combines gauge/absolute pressure measurement up to 1000 psi, RTD temperature sensing, and electrical signal logging (voltage, current, switch) into a single rugged unit. With an accuracy of up to 0.025% of reading, it can replace a deadweight tester for many calibration tasks, while its IP67-rated housing withstands immersion in up to 3 feet of water.
Key Features & Highlights
