Soil conductivity is checked before fertilizer application to pinpoint field needs and after fertilization to establish its effectiveness. The EC testing provides all agricultural operation with a method to optimize chemical applications and minimize operational cost.

This instrument has been designed to meet the Grower's need for equipment suited to the aggressive environments found in agricultural and hydroponics applications.

MW402 has a range of 0.0 to 10.0 g/L (ppt) with a 0.1 g/L resolution. The meter is supplied complete with TDS probe with 1 meter cable and calibration solution.

AI3102 LabSen 221 Glass-body pH Electrode for Viscous and Low Ion Concentration Samples by Apera

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 221 Glass-body pH Electrode is designed for titration and low ionic strength solutions as well as general water solutions. The electrode is compatible with TRIS buffer solutions.

LabSen S-type cylindrical glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage.

Movable Sleeve Junction - easy to clean, especially suitable for low ionic strength solutions, emulsions, and suspensions. The infiltration rate of the electrolyte can be adjusted by the tightness of the sleeve.

The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation.

• Built with LabSen S-type glass membrane, featuring fast response and high firmness
• Movable Sleeve Junction - easy to clean, adjustable infiltration rate
• Long-Life Reference System, improving the stability of the reference and extends the electrode's service life
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.

WD-35617-50 Electrode Stand (Use with Electrodes up to 14 mm diameter) by Oakton

Holds up to four standard size electrodes (14-mm dia max) and one ATC probe. Weighted 6" dia base lets you pivot holder 360° for added convenience. Flexible arm lets you move electrode side-to-side or up-and-down while keeping electrode at a constant vertical angle.

• Hands free pH measurement

WD-35608-50 Conductivity/TDS Cell, Ultem Body, Steel Sensor, 3 ft Cable, K=1.0 by Oakton

Feature built-in temperature compensation

• Ultem Cells with K = 1.0 have removable a probe guard for easy cleaning

Choose from three different cell constants:

• K = 1.0 for midrange conductivity measurements.
• K = 10.0 for high conductivity measurements (near or above 20 mS)
• K = 0.1 for low conductivity measurements (near or below 20 µS)

Each conductivity/TDS cell has a temperature range of 0 to 100°C.

874342 Chemcassette Tape, Aliphatic Amines/Ammonia by Honeywell Analytics

Chemcassette® is the unique trademarked name for a calibration free toxic gas detection method that uses an optical scanning system to detect the presence of gas by a colour change on the specially chemically impregnated paper tape. Chemcassette® technology is highly specific and reacts extremely fast to the presence of parts per billion (ppb) levels of many hazardous gases. Over 200,000 points of gas detection are currently maintained by the Chemcassette® sensing technology at any given time around the World in some of the most critical safety applications possible.

Each Chemcassette® is manufactured to traceable ISO 9000 manufacturing standards by a world class team of highly trained chemists and each batch is calibrated with ultra pure gas that is traceable to nationally accepted standards. This means that the end user does not have to provide calibration facilities themselves thereby saving cost and reducing risks to their own staff.

Efficient high volume manufacturing techniques means that there is always available Chemcassette® in stock that can be shipped anywhere in the World so that our customers are never left without adequate safety cover. Application support with expert gas detection chemists is available by phone and e-mail and is supported with many years of technical application notes and help to diagnose common support issues.

Should there be any concern regarding the performance of an individual Chemcassette®, a free of charge evaluation will be performed to trouble shoot the observed scenario using the award winning quality management system "Customer Discrepancy Report" CDR. Every CDR completed by a customer is guaranteed a full response and the outcome is reported directly back to the end user to ensure a complete resolution process.

Each Chemcassette® is backed with a full warranty and we have over 20 years of experience regarding the quality control of our proven sensing technology.

Additional Features and Benefits:

• Visible proof of a gas release event
• Greater sensitivity (detection down to parts per billion levels)
• Superior selectivity (less cross-interference with other gases)
• Fast response time
• Low false alarm occurrence
• Stability (consistent, repeatable operation)
• No calibration required
• Easy to use
• Available in fixed and portable instrumentation

517651BT Orthophosphate LR Reagent Set 0.05-4 mg/L by AquaPhoenix

Lovibond® Combi-Pack of Phosphate Low Range No 1 and No. 2 Tablets, 100 each

Test tablets are manufactured in Germany under tightly controlled conditions on the latest machinery. Maintaining the highest quality standards permits Tintometer GmbH to guarantee our reagent tablets for a minimum of 5 years, and some for as long as 10 years. We can make this promise because each tablet is hermetically sealed within an individual aluminum foil, protecting against challenging environmental conditions. This packaging keeps each tablet in perfect condition, right up until the time it is needed by the user. Test tablets remain the most consistent and reliable reagent format available, consistently outperforming other reagent formats, and delivering maximum accuracy for the user.

Now we have improved even further on this highly successful format. To the tight quality control processes, integral to Lovibond®'s tablet manufacture, and the simple test procedures, we have added new blister packaging. Our new aluminum foil blister packaging brings added convenience to the tradition of protection achieved in Lovibond's long established tablet production technology.

With the new blister strip, the user just pushes the tablet through the protective foil, straight into the sample. Simple, time-saving and practical. This type of packaging, long established in pharmaceutical applications, combines all the advantages of protective foil, with convenience for the user. Each tablet is contained within an individually formed foil cup, lined with the latest aluminum composite material, and guaranteeing product performance.

As a result of improved sealing efficiency, the blister pack has been reduced in size to 91 × 34mm making them even more convenient for storage and shipping. 'BT' is added to the end of the code to identify the new style of packaging. There are no safety risks if the tablets are used in line with the instructions supplied. Safety data sheets are available for all reagents.
