Gauges & Calibrators
Ralston Instruments' gauges and calibrators are born from decades of experience working with technicians, project managers and facilities teams responsible for maintaining metrology instruments.
Digital Pressure Gauges
Rugged, single pressure sensor digital gauges with optional Bluetooth and data logging capabilities in 0.25% or 0.1% accuracy.
Digital Thermal Probes
Digital probe thermometers designed for field and facility use with all metal probes compatible with a wide range of fluid and gas media. Bluetooth models include onboard data logging with FieldLab Mobile App for remote access and monitoring.
Pressure/Temperature Gauges
Perform hydrostatic tests and monitor multiple process variables on a single unit. Bluetooth models include onboard data logging with FieldLab Mobile App for remote access and monitoring.
Dual Pressure Gauges
Get more done with half the equipment. Dual Pressure Gauges measure pressure on both the high and low sides, providing a more integrated view of the system’s performance with clear, traceable results. Bluetooth models let you log and monitor readings remotely from your phone or tablet using the FieldLab Mobile App.
FieldLab Digital Pressure Calibrator & PSV Test System
The FieldLab Digital Pressure Calibrator is an intrinsically safe pressure calibrator/data logger that is ideal for a wide variety of environments including Zone 0 hazardous locations. The intuitive design makes it easy to create, plan, and run tests, and the FieldLab and FieldLab Desktop Software work together seamlessly to standardize work flows and distribute test requirements to teams. Enhanced PSV Test Mode utilizes high speed data logging capturing 200 readings per second to log exact crack and reseat values.
