Pressure and Flow Calibration Standards
 
 
Automated Mass Handling for Piston GaugesAutomated Mass Handling for Piston Gauges

• Introducing automated mass
  handling for piston gauges!

 

• Eliminate tedious, error prone
  manual mass manipulation from
  high end piston gauge
   operations.

 

• Allows fully automated
  pressure balance operation.

 

• An ultra-high performance
  alternative in pressure
  controller applications.

Hydraulic Pressure Controller Calibration Process Software Gas Pressure Controller Very Low Pressure Standard Reference Pressure Monitor Gas Flow Calibration System

DH Instruments, Inc. is a leading manufacturer of high performance pressure and gas flow standards including calibration process software. We offer a2La accredited pressure and gas flow calibration services, as well as metrology training courses.

For 25 years, DHI has specialized in pressure and flow calibration standards . These include PG7000 automated pressure balances, FPG very low pressure standard, a full range of digital pressure controllers and pressure monitors, and molbloc/molbox gas flow calibration systems.

We have complete calibration services for all types of pressure and flow measuring and controlling instruments. Our calibration laboratory has capabilities accredited to ISO 17025 and ANSI/NCSL Z540 by the American Association for Laboratory Accreditation (A2LA).
Custom Rack System

CUSTOM PRESSURE SYSTEMS
DHI can produce the complete pressure system that you need...from mobile calibration carts to turn-key automated calibration systems.

Mobile Cart System
 
 
A FEW DHI APPLICATIONS:

• Calibration of:
  - pressure transfer standards
  - portable calibrators
  - deadweight testers
  - transducers
  - transmitters
  - gauges
  - air data test sets
