MILD STEEL 4 COUPON RACK

Posted by craig.f@dtkwater.com

 

MILD-STEEL-4-coupons-DTKCR002_600x600

KEY FEATURES

  • Suitable for higher temperatures and pressures
  • Maximum operating pressure is 10 Bar or 145 psi
  • Can hold up to 4 corrosion coupons
  • Water Inlet & Outlet 1″ BSP, male
  • Corrosion coupon size 3 x 1/2″

DESCRIPTION

All DTK corrosion coupon holders incorporate a built-in flow control which will divert water flow through the rig at the ATSM recommended rate of 0.6 to 1.8 m/s for cooling water systems at presures between 1 and 7 Bar (14.5 to 101 psi).

Our corrosion coupon holders are designed for easy and inexpensive monitoring of corrosion within cooling water systems. Part of the cooling water is diverted from the main flow into the coupon holder where it passes over corrosion coupons before being returned to the cooling system. Corrosion coupons can be inserted and removed for analysis without the need to close down the system.

NOTES

The general layout of the corrosion coupon rack can be seen at the top, however the configuration is adaptable to the situation.

Assembly required. PTFE tape is included for sealing joints. Corrosion coupons not included but are available here.

Photometer and Fluorometer

MD640 800x800

      • PTSA within a high accuracy field photometer
      • Built-in PTSA measurement without adapter.
      • Over 120 methods.
      • PTSA measurement (florescence).
      • Data storage and transfer.
      • Bluetooth® connectivity

EXTENSIVE COVERAGE

The MD 640 has all the features of the MD 610, with added florescence capability for the determination of PTSA in water systems.

PTSA (1,3,6,8 pyrenetetrasulfonic acid, sodium salt) is a fluorescent material that is being increasingly added to specialty water treatment products to enable real time product dose analysis.

PTSA is detectable at ppb levels, is non-toxic and chemically stable, making it an ideal additive to trace throughout complex water systems.

The MD 640 has a built-in UV excitation LED that enables accurate detection and quantification of PTSA from 0 to 1000 ppb. No additional adapters or reagents required, just insert the sample and read the result.

Accurately measuring product dose levels help the water treatment specialist to control water chemistry; prevent corrosion, scale and biological fouling; increase system efficiency and ultimately save energy and costs.

The MD 640 is pre-programmed with over 120 analytical methods to enable quantification of naturally occurring dissolved metals and non-metals such as copper, iron, calcium, magnesium and carbonates, plus a range of water treatment additives such as DEHA, Molybdenum phosphate, poylacrylates, PTSA, organo-phosphate (phosphonates) and more empowering the field engineer to effectively manage many different water systems and treatments with one compact, waterproof and rugged handheld device.
