Ultrameter III 9PTK Titration Kit

AHL Titration Kit
Our latest digital handheld, the Ultrameter III 9P, is based on the tried and tested design of the Ultrameter II. The 9P adds the ability to perform in-cell alkalinity and hardness titrations either as stand-alone measurements or as part of an LSI calculation. Alkalinity, hardness, pH and temperature values can be manipulated in the LSI calculator to predict the effect of changes on water balance. Measurements are extremely accurate. And the 9P is simple to operate and maintain.Alkalinity, Hardness & LSI Titration Kit.
A hard foam-lined case organizes and protects all contents: The 9P; 9P cell extender; required reagents for in-cell alkalinity, hardness and LSI titrations; standard calibration solutions for all parameters; storage solution to protect the pH/ ORP sensor; and pipette for precision dispensing with additional tips. Sensors are internal and included. The 9P is also capable of wireless communication with the bluDock™ option installed. The bluDock uses Bluetooth® technology to transfer data wirelessly to your personal computer and comes with user-intuitive software that makes it easy to analyze saved water sample data. 9P Titration Kit
includes 9P; cell extender; 100µL pipette; 12 tips; 3 buffers (pH 4, 7, and 10); pH/ORP Sensor Storage Solution; ORP Conditioner Solution; titration reagents and standards H2SO4-1, HCl-3, NAOH, EDTA-LC, EDTA-HC, Alkalinity Standard 100 and Hardness Standard 200; standard solutions KCI-7000 and 442-3000. All bottles are 2 oz/59 ml. model: 9PTK

9PTK AHL Titration Kit can be ordered with the bluDock Accessory Package, as well. kit with bludock: 9PTK-BDIn-cell titration functions

The Ultrameter III adds the ability to perform in-cell conductometric titrations that provides a convenient way to determine alkalinity, hardness and LSI in the field. This eliminates the need to collect and transport samples to another location for analysis. User intuitive display prompts guide you through titration procedures from start to finish. All required reagents and equipment are included in the 9P titration kit. Hardness unit conversion

The Hardness titration, LSI Titration and LSI Calculator functions allow you to set the hardness unit preference to either grains of hardness or ppm CaCO3. Free chlorine readings

The Ultrameter III features the ability to convert Oxidation Reduction Potential measurements from mV to parts per million (ppm) free chlorine. The mV to ppm free chlorine conversion algorithm is based on a conversion curve developed through extensive testing performed by the Myron L Company. The accuracy of low-range ppm free chlorine readings has been increased by extrapolating from the published data. With this new feature Myron L instruments can measure a dynamic range of sanitizer concentrations that is wider than the range of a colorimetric test kit. Accuracy you can trust

Like the Ultrameter II, the Ultrameter III delivers exceptional accuracy of ±1% of reading (±.1% at calibration point). This high level of accuracy is achieved through advanced four-electrode conductivity cell technology, a powerful microprocessor, proprietary circuit design and conversion algorithms for three of the most common solution types, as well as a unique pH/ORP sensor. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels never before possible in such affordable instruments. For accuracy in diverse applications, Ultrameter III allows you to select from 3 solution modes that model the behavior of the most common solution types: KCl, NaCl and 442™ Natural Water. Additionally, the Ultrameter III features a user adjustable conductivity/ TDS conversion ratio for greater accuracy when measuring solutions not contained in the microprocessor. The Ultrameter III is factory calibrated with NIST traceable solutions. Certification of traceability and NIST traceable standard solutions can be purchased as accessories for definitive calibration. Innovative Engineering

The Ultrameter III is a prime example of how high-tech engineering can greatly simplify and streamline a task. Whether in the lab, industrial plant, or in a remote field location, electrometric measurements are accomplished in 3 easy steps:
1. Fill the cell cup
2. Push a parameter key
3. Take the reading

Temperature compensation and range selection are both rapid and automatic. User adjustable temperature compensation (up to 9.99%/°C) which can also be disabled for applications requiring non-compensated readings. Digital results display instantly. Measurement is continuous, displaying real-time readings rather than a static snapshot of the solution. Easy to calibrate

All calibrations are quickly accomplished by pressing the ▲ or ▼ keys to agree with our NIST traceable Standard Solution. When calibration is necessary, display prompts simplify pH calibration and make sure the correct buffer is being used. Plus, all parameters (excluding factory set temperature) have an internal electronic setting that can be used for field calibration and as a check on pH/ ORP sensor life. Water balance analysis

The Ultrameter III features both an LSI Calculator and an LSI Titration measurement mode. The Calculator allows you to perform what-if scenarios to predict how changes in solution parameters would affect the water balance of a system. The titration measurement function allows you to accurately calculate a saturation index value of a specific solution to determine whether the solution is balanced, scaling or corrosive. Wireless Benefits

The optional bluDock™ accessory package is an integrated data solution for your record keeping requirements, eliminating the need for additional hardware, wires and hassle. Because the user never touches the data, there is little opportunity for data tampering and human error. bluDock software has an easy to use interface with user intuitive functions for storing, sorting and exporting data.
