EcoPRO and EcoPRO+ 4-20mA Submersible Pressure Transmitter

Product Description

Applications such as environmental and wastewater sampling involve some uncertainty about what samples may contain. When dealing with unknown or unpredictable sample types, you need a durable pH probe you can trust to deliver accurate measurements regardless of the contaminants you encounter. The pH2000 has a double junction reference design to prevent reference fouling by heavy metals and other sample contaminants. When you travel to remote sites to collect data, it is especially important that obtaining the measurements you need is hassle free. The pH2000 features an Ultem® body and a booted meter connection for durability in the field. The sealed reference design requires no maintenance. Compatible with any meter accepting a BNC connector.

• Durable and low maintenance: Ultem® body construction, reinforced meter connection, and sealed reference design
• Great for testing unknown sample types: Double junction reference protection prevents reference cell contamination
• Accurate measurements across full pH scale (0-14)
• Instantly ready for use: Shipped in storage bottle for long shelf life – guaranteed for one year
• Compatible with any meter accepting a BNC connector
• One year limited warranty: We stand behind all our products with the Sensorex Guarantee

Key Benefits

Many water companies want to measure free chlorine residuals without the need for chemical buffers traditionally associated with such measurements. Acetate and phosphate buffers are expensive and environmentally unfriendly. Buffer delivery systems are maintenance intensive and have fairly costly consumables and there are health and safety considerations in the handling of the acids and high disposal costs if the acid treated water is unable to be fed back into the water supply. Amperometric cells and most polarographic probes only respond to hypochlorous acid, (HOCl). HOCl dissociates into hypochlorite (OCl–) in a pH dependent manner. This is why most chlorine monitors need acid buffers in most applications. The typical pH of water measured on a water treatment works may range from 7 to 9.2. Chemical buffering reduces the pH to between 5 and 6 and ensures that the majority of the residual chlorine is present as HOCl (see graph below).

• Low purchase cost
• Low cost of ownership
• Reduced pH dependency (largely pH independent)
• Stable and reliable
• Bufferless
• Reagentless

Key Benefits

UVA (ultra-violet absorbance) is an excellent surrogate parameter for TOC, DOC, COD and color.

UVT (ultra-violet transmission) allows for the calculation of optimal UV dose for disinfection systems, improving efficiency.

Accurate detection without the cost of reagents.

Few ongoing service or maintenance requirements.

Allows feed forward optimization of coagulation control, resulting in decreases in chemical consumption, reduction in sludge removal costs and minimization of DBP formation potential.

Strong ROI with pay back on the analyzer being seen by many customers within a few months.

UVA measurement ensures performance of various contaminant removal technologies such as membranes (RO, NF, UF), ion exchange (nitrates and TOC removal) and granular activated carbon (GAC).

Real time UVA analyzers can provide a final check of effluent water quality and can alarm an operator in case of non-compliance.

A UVA monitor can monitor the percentage removal of organics across any treatment system.

Can be combined with a CRONOS® or CRIUS® for a multi-parameter UV254 analyzer solution that suits your needs.

Product Description

In laboratory environments such as medical, biological, and materials science research groups, samples and test conditions are constantly changing, but accuracy is always critical. The pH3400 is a highly versatile glass combination pH electrode, specially designed to respond quickly and accurately to rapid temperature changes. The high sensitivity internals allow testing of low ionic samples. Safely measure samples containing heavy metals, TRIS buffer, or proteins thanks to the double junction reference design, which prevents fouling. Even test highly reactive chemicals: with a glass body, the pH3400 is inert to a wide range of chemical reactions.

• Our most sensitive laboratory electrode: accurate to 0.04 pH in tests across full recommended temperature range
• Easily maximize measurement repeatability: Rapid renew reference system for quick refilling
• Safe for use with reactive chemicals: Glass bodies are inert to many chemical reactions
• Ideal for difficult sample types: Double junction reference protection for testing samples containing heavy metals, TRIS buffer, and other contaminants
• Ready for wet or corrosive environments: BNC boot protects meter connection

Recommended for: Low ionic samples, medical and pharmaceutical research, biological samples (including TRIS buffer), samples containing heavy metals
