WD-17040-10 InnoCal NIST-Traceable Calibration; Pressure/Vacuum Gauge, Accuracy ?1% by Oakton

If your experiment or process relies on pressure and vacuum measurements, make sure these instruments remain precise through regular calibrations. InnoCal® performs NIST-traceable pressure calibrations on absolute, gauge, and vacuum measuring instruments from:

• Gauge, Absolute and Differential Pressure from 0 to 20,000 psig (1.38 mPa)
• Vacuum from 0 to 29.2 in. Hg (986 mBar)
• Barometric pressure from 700 to 1100 mBar

We can calibrate all styles of pressure and vacuum equipment including analog/dial gauges, digital gauges, transducers and transmitters, pressure calibrators, manometers, barometers, deadweight testers, and pressure comparators.

InnoCal services all major brands of pressure equipment including Ashcroft®, WIKA®, Crystal Engineering, Fluke®, Druck, GE Sensing, Cole-Parmer®, Extech®, 3D Instruments™, and many more!

To meet your calibration needs:

• All calibration certificates contain as-found and as-left data, estimated measurement uncertainties (emu's), and test uncertainty ratios (TUR's) at no additional cost!
• This NIST-traceable calibration allows you to confirm that the specific asset you purchase meets the manufacturer's published specification
• EPA, USDA, ISO, and GLP/GMPs standards require regular NIST-Traceable calibration of all test equipment being used in critical applications, FDA compliant
• Receive your product calibrated and ready to use rather than sending it to a third-party or internal calibration lab and incurring additional delays

All measurements reported are traceable to SI units via national standards maintained by NIST and performed in compliance with ANSI Z540, ISO17025, and MIL-STD-45662A.

InnoCal is accredited to ISO/IEC 17025 by the American Association for Laboratory Accreditation (A2LA) under certificate number 1746.01. This accreditation is your assurance that the calibration is performed in a qualified, controlled laboratory.

Calibrations on pressure and vacuum gauges are performed using direct comparison against ultra-precise quartz reference transducers. Pressure measurements can be taken up to 20,000 psi and vacuum measurements down to 29.2 inches of Mercury. The calibration consists of 5 points upscale and 5 points downscale across the range of the instrument.

LabSen 213 Glass Combination pH/Temp. Electrode for General Water Solutions (TRIS compatible) by Apera

Backed by proprietary Swiss sensor technology and materials, the Apera Instruments LabSen® 213 Glass 3-in-1 pH/Temp. Electrode is designed for general water solutions in scientific research and quality control. This electrode is compatible with TRIS buffer solutions.

LabSen® unique blue hemispherical glass membrane - faster response time, better repeatability, and built tough, highly resistant to general impact (totally differentiates from the traditional fragile glass bulb membrane); and can be tested in high-temperature samples (up to 225°F).

Long-Life Reference System - composed of a glass tube, AgCl, and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference electrode and extends the service life of the electrode.

The patented pH/Temperature combination structure - The temperature element is placed in an independent cavity under the pH glass membrane. With the built-in heat-conducting medium, the temperature sensing speed can be increased by 40%, hence the response time and stability of the pH electrode are greatly improved.

Compatible Apera Instruments' meters: PH700, SX823-B, MP511, PH910, PH950, PH850, PH8500, PH820. May NOT work with other brands' meters because the temperature unit might be incompatible.
