Industrial Ion Selective Sensors are specifically designed for continuous online service. Solid state manufacturing methods allow for ultra-thick ion sensitive membrane construction for long lifetime, and excellent performance under heavy use. Industrial Ion Selective (ISE) analyzer calibrates, operates & outputs a scaled 4-20 mA signal in convenient ppm units. (read more)

Special Optics, Inc., a Navitar company and manufacturer of high precision ultraviolet (UV) optical systems, has expanded their broad range of UV lenses to include a high N.A. UV microscope objective with a numerical aperture of 0.90. This is a great compliment to Special Optics current high N.A. UV line which includes 0.75 N.A. and 0.50 N.A. objectives. (read more)

The Polymetron 9245 provides low-level sodium measurement in high purity water applications. (read more)

Ball Valves and Sodium Hypochlorite: Sodium hypochlorite is inherently an unstable compound. As it decomposes, the resulting crystalline salts and oxygen gas can cause operational and safety issues with conventional ball valves. (read more)

Quantitative isolation of organically bonded halide as a prerequisite for classical potentiometric determination requires extraction of the halide from an organic medium into a water-soluble ionic form. The GFS Organic Halogen Reagent (Item# 5005) does this effectively and rapidly for samples that can be dissolved in an inert solvent,such as toluene or ether. (read more)

AC/DC Power photo sensors were developed to make use of the available power and are the majority of models are self-switching between AC and DC and self-regulating from 24 VDC to 240 VAC with Advanced circuitry allows for detection distances up to 30 meters... (read more)

• Detection limit of 0.01 ppb (0 to 10,000 ppb)
• 100 days between reagent changes
• Automatic reactivation ensures optimum response time and performance; no acid etching required!

Available in the US and Canada only. (read more)

X-ray fluorescence (XRF) spectrometry is a powerful analytical technique for elemental analysis of a wide variety of materials in a highly precise and generally non-destructive way. XRF can be used for many elemental analysis applications, such as electronics, plastics, rubbers, geology, forensics, and WEEE / RoHS / ELV compliance testing. (read more)
