A-0174 Electrode for I-1000 pH meter by AquaPhoenix

A-0174 is one replacement electrode and cap for the I-1000 pH Meter. When your pH Meter fails to calibrate or is showing fluctuating readings in calibration standards, replacing your electrode may be required.

The electrode and pH Meter are both manufactured by Oakton Instruments, Inc.

WS-220 22" Aluminum Shutter by Schaefer

Schaefer aluminum shutters allow airflow in a single direction and are used as building air inlets to feed Schaefer exhaust fans, or on exhaust fans to prevent air entry when the fan is not operating.

Aluminum shutters are built tough for long life in the most demanding environments, all at an affordable price.

Features and Benefits:

• Constructed of heavy-duty brushed aluminum for corrosion resistance and greater durability
• Interlocking louvers for maximum weather protection and lightweight for high efficiency and easy installation
• Tie bar to eliminate shutter flapping
• Shutter motor kits available for automated opening/closing

Measuring Range: -50 to +150 °C

21004 Calibration Std - 1000μS Conductivity / 100ppbPTSA - 500mL Bottle by AquaPhoenix

PTSA (1,3,6,8-pyrenetetrasulfonic acid tetrasodium salt) is used in cooling tower and reverse osmosis applications as a tracer for inhibitor concentration monitoring, known as fluorescence tracing.

Pyxis PTSA standards are manufactured under strict lab environment and quality control processes to ensure accuracy for calibration. It is ideal for checking and calibrating portable and/or inline PTSA fluorometers.

The innovative PTSA-1010 combines PTSA standard with conductivity standard that will calibrate both parameters with Pyxis SP-400 and SP-700 meters.

Shelf life is 6 months.

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.
