Calibrate air sampling pumps to set & verify flow rates with complete confidence – anywhere you work. Lightweight and easy to operate, the Go-Cal Pro is the must-have precision flow meter for OEHS professionals.

Portability

• Small, lightweight, durable design, and no moving parts
• Hand held ergonomic design makes it easier to hold and perform data entry
• Charges with a standard USB-C cable

Easy to Use

• Easy to setup (just connect tubing and start pump)
• Fast stabilisation – gives instantaneous reading
• Large Color Touch Screen Display
• Averages flow over user selected time
• Customisation of local languages and preferred units of measure
• Bluetooth^® Communications Options (coming soon)

Sampling Integrity

• Creates digital traceability which ties sampling chain together
• Flow Verification Event Storage
• Flow Meter report provides event information and information about the flow meter being utilised (i.e. serial number, date of last calibration)

Advanced Calibration Technologies

• Ability to select Sample Periods
• The user may select a specific sample time to be averaged
• Internal sensors standardise flow rates using reference temperatures and pressures (STP)
• STP-corrected flow rates facilitate data comparison across different environmental conditions, eliminating the need for external calculations
• Users can set corrected temperature and pressure values according to various standards
• On board computing can data log the calibration events and perform statistical analysis on the deviations between readings
• Users can define statistical parameters for percent deviation over the sample period
• Improved user interface capabilities with full touch screen keyboards for completing data input, and user defined fields for maintaining sample integrity
• Displayed date of last calibration, serial numbers, and reminders for next calibration due date
• Calibrators can generate printable calibration reports that include sample information, saved instrument settings, and sample flow rate results
